Technical Domain [0001] Disclosure realizations relate to an electrical device to change a demand response (DR) control level in order to adjust energy consumption, and an energy management device to control the same. Fundamentals of Technique [0002] With the development of Information Technology (IT), the number of household appliances powered by electricity is increasing rapidly, leading, in turn, to increased energy consumption. In order to satisfy such an increase in energy demand, the number of power plants is increasing rapidly. However, as can be seen from an energy demand pattern, peak capacity is not reached during most days of the year, that is, power plants only operate at full capacity for a few days of the year. [0003] A state, in which a high power demand is needed for a short period of time, is called a peak load. The construction costs for adding a new power plant to the grid are extremely high, and the maintenance costs for plants built to maintain peak load for a short period are considerable. [0004] Recently, several developers are conducting intensive research related to a demand management method to temporarily restrict energy consumption by limiting the peak load without building these additional power plants. For the aforementioned purposes, demand management is a focus of attention, and a great deal of research is focused on an advanced demand management format for demand response (DR). [0005] DR is a system for intelligent management of energy consumption depending on the variation in energy rates. For example, the consumer can temporarily shut down an air conditioner in order to reduce energy consumption when energy rates are high. [0006] Through DR, a power supply can change end-user power consumption to achieve load balancing, and can restrict end-user power consumption to periods when demand is low, reducing thus the total energy expenditure of the user. [0007] Therefore, an electrical device was developed, to which demand response (DR) is applied. The electrical device receives real-time power rate information from the power supply or power provider, and turns on or off in response to the received power rate information. [0008] However, since the conventional energy management system is unable to change or establish a level of DR control acting as an initial level of DR control, energy saving control is only achieved at a price level predetermined, and it is impossible for the conventional energy management system to control energy savings at another price level. In other words, the conventional energy management system can control the DR when the energy price reaches a predetermined energy price level. Disclosure of Invention Technical Problem [0009] Therefore, the conventional energy management system can only provide the information about current energy price level, and does not provide information about a DR control level, at which the energy saving control starts operation. Furthermore, although each fixture is designed to perform DR control at different predetermined price levels appropriate for individual fixtures, the conventional energy management system is unable to change a predetermined DR control level when the product is manufactured. As a result, although a user wishes to operate the fixture normally, the user is unable to operate the fixture normally, resulting in inconvenience. Solution to Problem [00010] Therefore, an aspect of the embodiment is to provide an electrical device to change a control level of DR, indicating an initial level of energy saving operation. [00011] One aspect of the embodiment is to provide an electrical device for changing a demand response (DR) control level, including: a memory unit for storing a plurality of DR control levels classified according to rates of energy; a communication unit for receiving a current energy rate and a current energy rate level related to the current energy rate from an energy provider; and a controller for comparing the current energy rating level with a desired DR control level, through the plurality of DR control levels, and determining whether to perform an energy saving operation. [00012] Another aspect is the embodiment to provide an energy management apparatus, which establishes a level of DR control, indicating an initial level of energy saving operation of all electrical devices installed in a residence, and change the level of DR control, resulting in the implementation of global energy management. [00013] Additional aspects of the embodiment will be defined in part below in the description that follows and, in part, will be evident from the description, or may be learned by practicing the invention. [00014] In accordance with an aspect of the embodiment, an electrical device for changing a demand response (DR) control level includes a memory unit for storing a plurality of DR control levels classified according to rates of energy; a communication unit for receiving a current energy rate and a current energy rate level related to the current energy rate, via a real-time energy provider; a user interface which, upon receiving a request to change a user's DR control level, displays a list of pre-stored DR control levels, and receives a DR control level to be changed by the user; and a controller to compare the current energy rating level with the changed DR control level, and determine whether to perform an energy saving operation. [00015] The controller can set a product-recommended DR control level, previously stored in the memory unit, when the product is manufactured, at an initial level of energy saving operation, and set the changed DR control level to an initial level of energy saving operation upon receiving a request to change the DR control level of the user interface. [00016] The controller, if the current energy rating level is equal to or greater than the DR control level, can decide to perform energy saving operation. [00017] The user interface can display the currently established DR control level for a predetermined period of time from when the fixture is turned on. [00018] The user interface can display a menu to change the DR control level, display the list of DR control levels, if the user selects a menu to change the DR control level, and receive a level of DR control to be changed from the list of user DR control levels. [00019] Information on recommended DR control level per product can be received through the communication unit. [00020] The user interface can display the current power rating level received from the communication unit and the recommended DR control level by product, and provide the electrical device information to the user. [00021] In accordance with another aspect of the embodiment, an energy management apparatus for changing a demand response (DR) control level includes a communication unit for receiving a current energy rate and an energy rate level current related to the current energy rate of a 'smartmeter' (smart meter) in real time, and receiving information about a plurality of electrical devices installed in a residence; a memory unit for storing the current received energy rate, the received current energy rate level, and information from the electrical devices, and a plurality of DR control levels classified according to individual energy rates; a user interface that, upon receiving a request to change a DR control level of at least one fixture from a user, displays a list of pre-stored DR control levels and receives a DR control level to be changed by the user; and a controller to compare the current energy rating level with the changed DR control level, and determine whether to perform an energy saving operation. [00022] The user interface can receive a request to change the DR control level for each fixture, and receive a request to change a DR control level for each fixture. [00023] The user interface, if the DR control level for each fixture is changed, can display a list of fixtures installed in a home, allow the user to select a fixture having a DR control level to be changed from the displayed list of fixtures, display the list of DR control levels of the selected fixture, and receive information about the DR control level to be changed by the user. [00024] The user interface, if the user selects the fixture, can display the information about the corresponding fixture received through the communication unit. [00025] The fixture information may include not only DR control level information currently established in the corresponding fixture, but also product-recommended DR control level information previously saved when the corresponding fixture is manufactured . [00026] The user interface can receive information about changing the DR control level in association with a plurality of electrical devices installed in the home, and receive a request to change the DR control level in association with at least one group including at least one fixture among the plurality of fixtures. [00027] The controller can determine, if there is an electrical device, whose currently established DR control level is equal to or less than the current power rate level, and control the corresponding electrical device to perform the energy saving operation . [00028] The memory unit can configure the list of electrical devices based on the information received from the plurality of electrical devices, store the list of configured electrical devices, and store information about electrical devices corresponding to the list of electrical devices. [00029] The communication unit can periodically receive information about various electrical devices installed in a home. [00030] The controller can compare the pre-stored electrical device list with the electrical device information received periodically and update the electrical device list according to the result of the comparison. Advantageous Effects of the Invention [00031] The power management unit and a method for its control, according to the embodiments, may allow the user to select a desired DR control level, so that an appropriate DR control level for the variation of the energy rate level can be determined. Therefore, energy can be effectively utilized, according to individual energy rate levels. [00032] As is evident from the above description, the fixture to change a DR control level and an energy management apparatus to control the same, according to the embodiment, can decide whether to increase the use of the electrical device, or consider the energy saving aspect, using current power state information, transmitted in real time, thus adaptively adjusting an initial level of DR control. Therefore, although the user wants to operate the fixture normally without the power-saving control of the fixture, it is impossible for the user to operate the fixture normally. [00033] In addition, the energy management apparatus, according to the present invention, can increase a level of DR control, indicating an initial level of DR control of the fixture, which should be more focused on the utility, when Instead of the energy saving aspect, so limited energy resources can be utilized according to the user's intention. [00034] Embodiments can simultaneously check current power consumption states and DR control level degrees of electrical devices installed in a home. In addition, embodiments can change a DR control level of each device, according to fixtures, or according to individual groups, resulting in more energy efficient control. [00035] Meanwhile, embodiments can be recorded as computer programs, and can be implemented in general purpose digital computers, which run the programs using a computer readable recording medium. Furthermore, the data structure used in the embodiments described above can be recorded on a computer-readable recording medium by various means. Examples of computer readable recording media include magnetic storage media (eg ROM, floppy disks, hard drives etc.), optical recording media (eg CD-ROMs or DVDs) etc. Furthermore, if a plurality of display modules are provided, images are displayed in a multi-screen performance mode, thus potentially improving beauty and effectively catching the customer's attention. [00036] In addition, the brightness or transparency of a transparent display module is adjusted in response to determining whether a human body has been detected, thus potentially reducing energy consumption. [00037] Although some embodiments have been shown and described, it should be understood by those skilled in the art that changes can be made to these embodiments without departing from the principles and spirit of the embodiment, the scope of which is defined in the claims and their equivalents.

Modality for the Invention [00039] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, where like reference numbers refer to like elements throughout the document. An electrical device for changing a DR control level and an energy management apparatus for controlling the same will be described below with reference to the accompanying drawings. [00040] Fig. 1 illustrates a power management system, according to an embodiment. [00041] Referring to Fig. 1, an energy management system may include an energy provider 100, a 'smartmeter' 200, an energy management unit 300 and an electrical device 400. [00042] Power provider 100 is an energy supply source, which is operated by an energy supply company (public utility company), which generates and supplies energy. The energy provider 100 generates the energy, through atomic energy, hydroelectric energy, geothermal energy, wind energy etc. and supplies the energy generated for the 400 electrical devices installed in each residence. [00043] In this case, in relation to the energy supplied to the electrical devices installed in homes, a predetermined amount of energy is generated every hour, so that the generated amount of energy is supplied to each residence. In contrast, different amounts of energy are consumed in each household, according to individual periods. For example, each household's energy consumption during a dawn or morning period is less than during another period such as twilight or afternoon. In addition, each household's energy consumption in spring or fall is less than in summer or winter. [00044] Therefore, the power provider 100 determines the power rate of a low power period to be less than that of a high power period, determines the power rate of a low power season of energy, as being less than in a high energy consumption season, and provides the energy of the determined energy rate for each household. [00045] The power provider 100 elastically adjusts the power rates of each household, in response to each household's energy consumption, and provides the adjusted energy to each household so that demand can be balanced. [00046] That is, the energy provider 100 predicts energy consumption based on the amount of electricity generation, historical information on energy consumption for each season and each period, and weather information, and determines rates of energy based on predicted energy consumption. [00047] In addition, the energy provider 100 can establish an energy rate level, where the energy rate can be classified according to a predetermined reference. [00048] Energy provider 100 collects energy consumption amounts from individual households, sorted according to individual energy rates, and stores the collected energy consumption information, according to individual energy rates, for power supply company calculates energy rates (electricity bills or electricity bills) depending on energy consumption for each household's individual energy rate levels per month, and charges each household the calculated electricity bills on a monthly basis. [00049] The energy provider 100 periodically compares the monthly calculated energy rate (monthly bills) with predetermined monthly energy rates to decide the energy bills. If the monthly calculated energy rates are higher than the predetermined monthly energy rates, information about the excess of the predetermined monthly energy rates is transmitted to the energy management unit 300 installed in the corresponding residence, for an event indicating the excess rates monthly amounts of predetermined energy is generated through the energy management unit 300 installed in each home. [00050] The energy provider 100 stores a threshold energy amount for each household, compares the amount of energy consumption for each household with a threshold energy amount, and therefore decides on an energy threshold. [00051] In this way, the energy provider 100 manages the energy demand of each household, based on the amount of capped energy, or on predetermined monthly energy rates. [00052] In this case, the amount of power limit to limit the power supply of each household may be arbitrarily determined by the power supply company, or may be determined by agreement with the power supply company for each household. In addition, each household's predetermined monthly energy rates are determined by agreement with the utility company. [00053] The energy provider 100 stores and manages information about exceeding a threshold energy amount for each consumer, energy consumption status information about exceeding predetermined monthly energy rates, and the like. [00054] The energy provider 100 is connected to the smartmeter 200 installed inside (or outside) each residence, the energy management unit 300, and each electrical device 400 in a network, so that information about energy demand management can be transmitted and received over the network. This network can be a wired network, a wireless network, a hybrid wired/wireless network, etc. [00055] The smartmeter 200 is installed inside (or outside) each home, and includes a display, such as a liquid crystal display (LCD), so that the energy consumed by the home is displayed in real time. [00056] The smartmeter 200 can be an electronic meter, which communicates bidirectionally with the energy provider 100, and transmits the amount of energy consumed to the energy provider 100 and the energy management unit 300. [00057] The smartmeter 200 receives energy rate information from the energy provider 100, displays the received energy rate information, and transmits the energy rate information to the energy management unit 300. [00058] In addition, the smartmeter 200 can further display an energy rate level corresponding to the energy rate information by receiving the energy rate information from the energy provider 100. [00059] In this case, the number of power rate levels can be 5 (RTP1 to RTP5), and a plurality of levels can have different power rates and different allowed instantaneous energies. Let's assume the number of power rate levels is 5 (RTP1 to RTP5). In more detail, the RTP1 energy rate level is the lowest energy rate level, and the RTP5 energy rate level is the highest energy rate level. The energy rate level is proportional to the energy rate. [00060] In this case, it is possible for the smartmeter 200 to transmit both the energy rate information and the energy rate level information to the energy management unit 300 when receiving the energy rate information and the information about the energy provider's fee level 100. [00061] The power management unit 300 may also be referred to as a Demand Response (DR) controller. [00062] The energy management unit 300 communicates with the smartmeter 200 and thus receives an energy rate and an energy rate level corresponding to the energy rate from the smartmeter 200. In addition, the management unit Power device 300 communicates with fixture 400 to receive information from fixture 400, and controls the operation of fixture 400 based on the rate of power received from smartmeter 200 and information about power received from fixture 400. [00063] If the power provider 100 transmits power rate level information corresponding to the power rate information, the power management unit 300 can also receive power rate level information as required. [00064] In addition, the energy management unit 300 can also establish an energy rate level based on the energy rates, by receiving the energy rates from the energy provider 100. [00065] In this case, the energy management unit 300 receives energy rate information through the smartmeter 200 at intervals of one unit of time, and sets an energy rate level of the received energy rate based on a predetermined reference . [00066] The energy management unit 300 receives information on excess energy limit and information on monthly predetermined energy excess rates from energy provider 100, and reports the information received to the user. [00067] Electric device 400 can be any one of a television, a washing machine, a dryer, a vacuum cleaner, an air conditioner, a stove, an electric oven, a refrigerator, etc. However, he is not limited to them. The fixture 400 communicates with a user interface 430 through which the user can enter commands. If the current time reaches a predetermined reserve time, the fixture 400 transmits information about the reserve time to the energy management unit 300. The fixture 400 is actuated in response to the actuation command from the energy management unit 300 , the energy consumed to drive the electrical device 400 is measured and information about the measured energy is transmitted to the energy management unit 300. [00068] One embodiment provides an electrical device and an energy management unit, which provide current DR control level information to a user, at which energy saving control begins, receives a request to change the information about user DR control level, and perform DR control, and a method to control the fixture and power management unit. [00069] Fig. 2 is a detailed block diagram, illustrating an electrical device, according to an embodiment. [00070] Referring to Fig. 2, the user can change a current level to a desired DR control level for each fixture. Electrical device 400 may include a communication unit 410, a controller, 420, a user interface 430, and a memory unit 440. [00071] The communication unit 410 communicates with the energy management unit 300, receives energy rates and energy rate level information divided for each energy rate, and transmits received energy rates and energy level information. power rate to the 420 controller. [00072] The communication unit 410 can (periodically or based on a user's request) communicate with the power management unit 300, so that the communication unit 410 receives the current power rate and rate level information of energy corresponding to the current energy rate. [00073] In this case, the energy rate level, according to the embodiment, can be divided into 5 levels (RTP1 to RTP5) based on a predetermined reference, according to the energy rate. However, it is not limited to them. The power rate is sequentially increased in the order of RTP1 ^ RTP2 ^ RTP3 ^ RTP4 ^ RTP5. [00074] Such energy rate level can be changed, according to the policy of the energy provider, and the communication unit 410 receives the information about the changed energy rate level and stores the received information in the memory unit 440. [00075] In addition, if a product-recommended DR control level corresponding to a reference provided by the manufacturing company is not previously stored in memory unit 440, communication unit 410 receives the product-recommended DR control level . In more detail, the communication unit 410 accesses the manufacturing company's server, via a wired network, or a wireless network, so that it can receive the aforementioned product-recommended DR control level as an input. [00076] The product recommended DR control level information received is stored in memory unit 440 and is defined as an initial DR control level for triggering the product. [00077] The controller 420 receives the power rate level information from the communication unit 410, configures a plurality of rate levels corresponding to a plurality of power rates in a DR control level list form, where the energy saving operation is initiated, and stores the configured list in memory unit 440. [00078] The controller 420 compares the energy rating level received from the communication unit 410 with a currently set DR control level, and determines whether to perform the energy saving operation according to the result of the comparison. In more detail, the 420 controller decides to perform energy saving operation when the energy rate level is equal to or greater than the currently established DR control level. [00079] Furthermore, upon receiving a request to change the DR control level to a desired DR control level by user interface 430, controller 420 stores the desired DR control level in memory unit 440, and sets the stored DR control level to an initial level of energy saving operation. [00080] The 430 user interface can be implemented as a display, such as a liquid crystal display (LCD), so that a data input part and a data output part can be integrated into one unit (for example , a touch screen), or can also be separated from each other as required. Alternatively, a button is implemented on a part of the screen so that the data input part and the data output part can be separated from each other in the 430 user interface. [00081] User interface 430 receives an indication signal corresponding to the indication of the user, generates various information corresponding to an indication message from the controller, and informs the various information to the user. [00082] Fig. 3 shows, exemplarily, a screen image of a user interface of the fixture shown in Fig. 2. Referring to Fig. 3, user interface 430 can display a control level of DR currently set for a few seconds when the fixture is turned on, or it may continuously display such level of DR control currently set on a part of the fixture. [00083] Referring to Fig. 3, user interface 430 displays the list of DR control levels arranged in ascending numerical order of power rates. That is, RTP1, corresponding to the lowest energy rate level, is located at the bottom, and RTP5, corresponding to the highest energy rate level, is located at the highest part. However, it is not limited to them. [00084] In addition, the 430 user interface displays a currently established DR control level in the list of displayed DR control levels. That is, when the DR control level moves from a lower part to an upper part in the screenshot of Fig. 3, it can be recognized that the energy saving operation is performed in descending numerical order of energy rates. [00085] The current DR control level, according to the embodiment, is displayed in different lights and hues in the list of DR control levels, so that the user can easily recognize the current DR control level. Such current DR control level can be displayed in different colors, or it can be displayed as an animation located in a part of the DR control levels list. [00086] In this way, if the current DR control level is displayed for a predetermined period of time, the user interface may be prompted to change the user's DR control level. [00087] Figs. 4, 5, and 6 show exemplary screen shots, illustrating that the DR control level has been changed by a refrigerator's 430 user interface serving as an electrical device. [00088] Referring to Figs. 4 and 5, the 430 user interface displays the current time, control information such as a current refrigerator control temperature, and an options menu. [00089] If the user selects the option menu, a first menu window to provide the recommended DR control level information by product and the current energy rate level information, and a second menu window to change a DR control level are displayed. [00090] If the user selects the second menu window to change a DR control level, the list of DR control levels is displayed so that a DR control level to be changed can be selected as shown in Fig. 8. [00091] When receiving a DR control level to be changed from among the user's DR control level list, a "Do you want to complete the DR control level change " dialog window is displayed. If "Yes" is selected by the user, the DR control level change is completed. [00092] The changed DR control level is stored in memory unit 440 by controller 420. During the next DR control, the changed DR control level is used. [00093] Fig. 7 illustrates a method for controlling an electrical device, according to another embodiment. [00094] Referring to Fig. 7, if the fixture is powered (Operation 510), information about currently established DR control level is displayed on the user interface for a predetermined period of time (Operation 520). [00095] Current DR control level information can be displayed for a few seconds once the fixture is turned on, or it can be displayed continuously in a part of the user interface, or it can be displayed at user request. [00096] Meanwhile, the currently established DR control level information may be information on the recommended DR control level per product, predetermined by the company manufacturing the product, or it may be a DR control level established by the user, when the electrical device is turned on. [00097] Meanwhile, the recommended DR control level per product can be pre-stored in memory unit 410 when the product is manufactured. If the product-recommended DR control level is not previously stored in the memory unit 440, the electrical device can access the manufacturer company server through the communication unit 410 in order to directly receive the DR control level information recommended by product, and store the received information in memory unit 440. [00098] If the current DR control level is displayed in 520 operation, the 420 controller transmits a control signal to the communication unit so that it receives current power rate information and corresponding power rate level information. at energy rate (Operation 530). [00099] The current power state information can be updated, via the communication unit 410, at predetermined time intervals, and the received current power state information is stored in the memory unit 440. It is also understood that the power state information can be updated when power state information changes. [000100] However, although the energy rate level information, according to the embodiment, can be divided into 5 levels (RTP1 to RTP5), the number of energy rate levels can be changed, according to the policy of the power supply company, and the changed power rate level can be transmitted through the communication unit 410, and updated in the memory unit 440. [000101] The user can recognize the current power state information and the product recommended DR control level information, which are stored in the 440 memory unit through the user interface, so that the user can change the power level. DR control, taking into account the utility or energy saving aspect of the fixture 400, based on the recognized information. [000102] In more detail, in order to increase the utility of the fixture, a DR control level is set to be higher than the currently established DR control level, so that energy saving control is performed at from a specific point in time, where the energy rate becomes relatively expensive. In addition, in order to increase the energy saving aspect of the fixture, the DR control level is adjusted to be less than the current DR control level, so that the time, in which the energy saving control energy runs, is relatively larger. [000103] If changing the DR control level is selected by the user (Operation 540), the controller stores the changed DR control level in memory unit 440, and updates the current DR control level information (Operation 550). The controller 420 then determines whether to perform power saving control based on the current DR control level and current power state information (Operations 560, 571, and 572). [000104] More specifically, if the energy rating level corresponding to the current energy rating is equal to or greater than the current DR control level (Operation 560), the controller performs energy saving control (Operation 571). Otherwise, the 420 controller controls the normal drive operation (Operation 572). [000105] As a result, the user determines whether to increase the utility of the electrical device, or consider the energy saving aspect, using the current energy state information transmitted in real time, so that the user can adaptively adjust the initial level of DR control. Therefore, the embodiment can solve the problem that the related art is unable to perform the normal operation desired by the user. [000106] As described above, although a DR control level is set for each fixture installed in each home, a fixture having no separate user interface can be present when needed, or it is necessary to manage a level. of DR control in conjunction with a plurality of electrical devices. [000107] An energy management unit to control the entire DR control level of all electrical devices installed in each household, and a method to control the energy management unit, will be described in detail below. [000108] Referring to Fig. 8, the power management unit 300 includes a communication unit 310, a controller 320, a user interface 330, and a memory unit 340. [000109] The communication unit 310 communicates with the 'smartmeter' 200, receives the energy rate and energy rate level information corresponding to the energy rate from the 'smartmeter' 200, and transmits the received information to the controller 320. The communication unit 310 communicates with the electrical device 400, receives information about the electrical device, transmits the received information to the controller 320, receives the actuation control signal of the electrical device 400 from the controller 320, and transmits the received drive control signal to electrical device 400. [000110] In this case, information about electrical devices may include a device name, energy information, predetermined information about recommended DR control level by product, when the device is manufactured, and the like. Information about electrical devices is stored in memory unit 340. In this case, energy information may include average power consumption, average operating time information, etc. [000111] In addition, the communication unit 310 can periodically receive information about the electrical device installed in a residence, and update the information about electrical devices stored in the memory unit 340. [000112] In more detail, the communication unit 310 receives information about the newly installed electrical device in a household, and stores the received information in the memory unit 340. In addition, the communication unit 310 transmits the information received from the electrical device to the controller 320, so that information about the uninstalled fixture in each household can be deleted from the memory unit 340. [000113] The controller 320 compares the power rate level information received from the communication unit 310 with an established DR control level for each electrical device. If there is an electrical device, the current power rate level, which is equal to or greater than the DR control level, the controller 320 transmits a control signal to the communication unit 310, such that the energy-saving operation. power can be carried out to the corresponding electrical device. [000114] If controller 320 receives a request to change the DR control level to a desired DR control level, through user interface 330, controller 320 stores the desired DR control level in memory unit 340 . [000115] The 320 controller allows each fixture to display the currently established DR control level information. If the currently established level of DR control is maintained, information about the predicted electricity bill can also be displayed on the 330 user interface. [000116] In more detail, the controller 320 can calculate the forecast electricity bill, using information about the average operating time of each electrical device, stored in the memory unit 340, information about the current energy rate level, and the control level of current DR. [000117] In addition, the 320 controller can also display the recommended DR level information in the 330 user interface. In more detail, by receiving the priority information of the fixture installed in homes and the current energy rate level information , the 320 controller can provide information about DR control level suitable for each electrical device. [000118] Priority information of various electrical devices can be pre-set and stored in memory unit 340. Alternatively, priority information of multiple electrical devices can be entered by the user, so that the entered priority information can be stored or changed. [000119] The 320 controller controls a high priority fixture to have more information about DR control level, at which energy saving operation is initiated, compared to a low priority fixture so that the power resources energy limited to the high priority fixture can be centralized (used). [000120] The controller 320 compares the current electrical device information received from the communication unit 310 with the electrical device information stored in the memory unit 340. Therefore, the controller 320 can erase the electrical device information, which is stored in the memory unit, but not contained in the current electrical device information, of the 340 memory unit, or can update the current electrical device information. [000121] Therefore, the memory unit 340 of the power management unit 300, according to the embodiment, may periodically (or non-periodically, or by a user's request) update information about the currently installed electrical device in every home. [000122] The 330 user interface can be implemented as a monitor, such as a liquid crystal display (LCD), and an input part and an output part of the 330 user interface can be integrated into one unit, such as a touch panel. Alternatively, the user interface 330 can receive user information via 7 segments or a button, or the input part and the output part can be separated from each other in the user interface 330. [000123] The 330 user interface displays power rate level information, DR control level information etc., receives a request to change the DR control level to a user desired DR control level , and displays the information received. [000124] The 330 user interface displays a current power rating and a power rating level corresponding to the current power rating. [000125] Figs. 9 and 10 show exemplary screen images of the power management unit user interface, according to an embodiment. [000126] Referring to Figs. 9 and 10, user interface 330 displays the current power rating and power rating level information corresponding to the current power rating. [000127] In this case, the information on the energy rate level is classified into 5 levels (RTP1 to RTP5), according to the energy prices. As can be seen in Fig. 10, the current energy rate is $5 per watt hour, and this energy rate corresponds to RTP3. [000128] However, although the disclosure embodiment exemplarily divides the energy rate level information into 5 levels, according to the energy rates, the number of energy rate levels can be changed, in accordance with the utility's power supply policy. [000129] In addition, according to the disclosure embodiment, although the energy rate levels are arranged vertically in ascending numerical order, note that the energy rate levels can also be arranged in ascending numerical order, so horizontal or circular. If necessary, energy rating levels can also be displayed in various ways, which represent high and low energy rating levels, without departing from the scope or spirit of the embodiment. [000130] If the energy rate level information displayed on the 330 user interface is confirmed as described above, the user selects a menu of options so that the user can recognize a variety of current states, eg the information on DR control level, historical energy rate information, and instantaneous allowable energy information for each household. [000131] The 330 user interface may allow the user to change the DR control level information. [000132] In more detail, the 330 user interface can provide information about a current DR control level, where DR control for each electrical device is initiated, and information about recommended DR control level by product, previously stored in the device electrical when the product is manufactured so that the DR control level can be changed based on the information received. [000133] In addition, if the current DR control level information and the current DR control level information are kept, the 330 user interface can provide the predicted electricity bill information and the DR control level information recommended. [000134] In addition, the recommended DR control level can be a DR control level, which reflects the priorities of various electrical appliances installed in a home, so that it can implement power control, where only the usefulness of an electrical device having relatively high priority is considered. As a result, limited power sources can be centralized (used) to the highest priority fixture. [000135] The appearance of the 330 user interface, for confirming the power consumption state of individual electrical devices, will be described below with reference to Figs. 11 and 12. [000136] Referring to Figs. 11 and 12, if a refrigerator is chosen from the list of fixtures installed in a household, a menu window is displayed. The menu window allows the user to view not only information about DR control level where the refrigerator's energy saving operation starts, but also information about recommended DR control level by product, indicating a predetermined level of assigned DR control when the refrigerator is manufactured, and can also change the DR control level to a desired DR control level. [000137] When receiving a menu to display the user's current DR control level, a current DR control level, information about the predicted electricity bill, when the current control level is maintained, and level information are displayed. of DR recommended. [000138] In more detail, the user can recognize that the refrigerator's current DR control level has been established, so that the refrigerator's energy saving control can be started, from the time corresponding to the RTP3 energy rate level . Furthermore, since the current energy rate level is RTP3 (see Fig. 3), it can be recognized that the refrigerator is subject to energy saving control. [000139] The 330 user interface can change a DR control level, according to individual fixtures, according to all fixtures, or individual groups. [000140] A method of changing the DR control level to a desired DR control level using the user interface will be presented below with reference to Figs. 13 and 14. [000141] Figs. 13 and 14 illustrate a method for changing the DR control level for each fixture, according to the embodiments. [000142] If the user selects a refrigerator and enters a command to change a refrigerator DR control level to a desired DR control level, the user interface displays the list of changeable DR control levels. [000143] In this case, the list of DR control levels can be the same or the same as the above mentioned power rate level information, and can be changed according to the utility power supply policy. [000144] Furthermore, according to the embodiment, the list of DR control levels is vertically arranged in ascending numerical order of power rate levels. Assuming that information about the high energy rate level, or the low energy rate level, can be provided to the user, the list of DR control levels can also be displayed in different ways. For example, the list of DR control levels can also be arranged horizontally or circularly, without departing from the scope or spirit of the embodiment. [000145] If the list of DR control levels is displayed, the user selects RTP4 (a step higher than a currently established DR control level) so that the user can still consider usefulness or usage. In addition, the user can select a DR control level lower than the currently established DR control level, taking into account the energy saving aspect. [000146] If the DR control level is changed as described above, the energy saving control is performed at a specific time where the current energy rate level is equal to or higher than the DR control level. [000147] Figs. 15 and 16 are a conceptual diagram illustrating a method for changing a DR control level for all electrical devices installed in each household. [000148] If the 'Select All' menu is entered via the user interface, information indicating that all electrical devices installed in each household are targets for changing the DR control level is displayed. [000149] If the 'Select All' menu is selected, a desired DR control level from the list of DR control levels is received so that the user can simultaneously change the DR control levels of all electrical devices. [000150] Figs. 17 and 18 illustrate a method for changing a DR control level, by establishing a group among all electrical devices, according to one embodiment. [000151] If the 'Group Definition' menu is entered via the user interface, various fixtures having DR control levels to be changed to a desired DR control level can be selected according to individual groups. [000152] In more detail, the user can define the group by dragging or selecting the list of fixtures one by one if necessary. [000153] In addition, if at least one fixture is selected as a group, several groups can be further established through a 'Set another Group' menu. For example, once the 'Group Definition' menu has been established, 'Fridge' and 'Washing Machine' are selected, messages about complete group name and group definition are entered, the group definition of the first group is completed . The user selects the menu 'Define another Group', so that the user can establish other groups, which are not from the pre-established group. [000154] If multiple groups are established as described above, the DR control levels for individual groups can be changed. As a result, the DR control level for each group is changed so that the user can conveniently change the DR control level without any difficulty. [000155] Fig. 19 illustrates a method for controlling a power management unit, according to another embodiment. [000156] Referring to Fig. 19, the power management unit, according to the embodiment, displays current power rate information received from the communication unit, and the corresponding power rate level information to the power rate information received via the 330 user interface (Operation 610). [000157] In addition, the 330 user interface displays the currently established DR control level for each fixture and the recommended DR control level information by product (Operation 620). [000158] In addition, the 330 user interface can provide the current DR control level information, the predicted electricity bill information found, when the current DR control level information is kept, and the level information DR control options, where the priorities of various fixtures are reflected. [000159] Based on the information provided for each fixture, the user can select a DR control level change menu via the user interface and select a DR control level to be changed in the list window. DR control levels so that the current DR control level can be changed (Operation 630). [000160] The above mentioned DR control level change can be performed for each fixture. In addition, a group is created so that you can perform the above mentioned DR control level change operation for each group. If necessary, all electrical devices can be controlled to have the same level of DR control. [000161] Upon receiving a request to change the DR control level to a user-desired DR control level (Operation 630), the controller 420 stores the desired DR control level and information about an electrical device 400 corresponding to the desired DR control level in memory unit 340 (Operation 640). [000162] If the desired DR control level is stored (Operation 640), the controller 420 compares the current power rate level information periodically received from the communication unit with a DR control level of each electrical device 400, for it to determine the presence or absence of an electrical device, to have its energy savings controlled (Operation 650). [000163] In more detail, the 420 controller determines the presence or absence of an electrical device whose DR control level is equal to or greater than the currently established DR control level (the desired DR control level), transmits a control signal to the corresponding fixture so that it controls fixture 400 with respect to the energy savings to be controlled (Operation 650).
