The reduction schedule information is received by the receiving unit 210 from each of the terminal devices 100a to 100c of the houses 20a to 20c (see FIG. 3).

  The information for specifying the reduction amount is information used to specify the reduction amount when the power usage is reduced by the device control in the house based on the content of the device control in the reduction schedule information. FIG. 4 shows an example of the configuration and content of the reduction amount specifying information. In the example of the figure, the reduction amount specifying information indicates that the DR period length is 1 hour, and the amount of power consumption that is reduced compared to the case of not saving power (normal time) for each device and for each content of device control. The amount of reduction is specified. For example, when one TV is turned off for one hour, the power consumption in the house is reduced by 0.3 kWh compared to the normal time, and when one air conditioner is turned off, the power consumption in the house is reduced by 1 kWh than the normal time. Etc. are prescribed. This reduction amount specifying information is determined in advance by experiments using various devices, theoretical considerations, and the like. For convenience of explanation, FIG. 4 shows a simple example of the reduction amount specifying information. However, if the reduction amount specifying information is determined so that the reduction amount can be specified in accordance with the contents of the device control in the reduction schedule information. Any information may be used. For example, as the information for specifying the reduction amount, the reduction amount may be defined in correspondence with each device control for each manufacturer, model identification code (model number), etc. of various devices such as a television and an air conditioner. In this case, information such as manufacturers and model numbers of various devices installed in the houses 20a to 20c may be registered in advance in the server device and used for specifying the reduction amount.

  The DR management information is stored in the storage unit 220 for each DR command corresponding to one DR period. FIG. 5 shows a configuration and example contents of the DR management information. First, a group of consumers (such as houses 20a to 20c in one area) to be a target for which a power company or a DR aggregator makes a DR command (request for reduction of power usage in a DR period) is assumed. Next, the electric power company or DR aggregator determines the target value (the number of target houses) of the number of customers (that is, the number of houses such as houses) to cooperate with the request, and the target of the amount of reduction in power usage that is reduced by cooperating with the request. Determine the value (target reduction amount). And the privilege information which is the information of the privilege (reward) provided with respect to the group (the houses 20a-20c etc. in one area) of the consumer when the target is achieved is defined. The DR management information including the DR period, the target number of eaves, the target reduction amount, and the privilege information shown in FIG. 5 is obtained by associating the target value and privilege determined in this way with the DR period and inputting from the input device. The data can be stored in the storage unit 220. As the number of group reduction eaves in the DR management information, reduction schedule information indicating that there is a reduction amount among a group of customers (a group of facilities such as houses 20a to 20c) is transmitted from the terminal device of the facility (house) The number of facilities completed is recorded. In addition, in the DR management information collective reduction amount, the total value of the reduction amount of power usage at each facility specified based on the content of device control of the reduction schedule information received by the receiving unit 210 is recorded.

  The specifying unit 230 refers to the reduction amount specifying information in the storage unit 220, and based on the reduction schedule information received by the receiving unit 210 from each terminal device 100a or the like, a group of consumers (facility (Group) It has a function of specifying a reduction amount of power use in the DR period in the whole. That is, the identifying unit 230 refers to the information for identifying the amount of reduction, identifies the amount of reduction in power usage of the houses 20a to 20c, etc., according to the content of device control in the received reduction schedule information, and Specify the amount of reduction in power usage during the DR period across the target facility population. The specifying unit 230 is realized by the processor 202 that executes a control program stored in the memory 201. The specifying unit 230 records the specified reduction amount (reduction amount in the group of facilities targeted by the DR command) in the DR management information of the storage unit 220. In addition, the identification unit 230 indicates the number of facilities transmitted from the terminal device of the facility (housing) in the DR management information in the facility group such as the homes 20a to 20c. Record the number of group reduction eaves. Since the reception unit 210 can receive the reduction schedule information at various points before the DR period, the specifying unit 230 receives the reduction amount information every time new reduction schedule information is received and stored in the storage unit 220. Perform identification and update the DR management information group reduction amount and the number of group reduction eaves. The specifying unit 230 specifies the reduction amount and updates the DR management information not at every reception of the reduction schedule information but at a plurality of timings such as every predetermined period or every predetermined time. It is good as well.

  The transmission unit 240 refers to the DR management information in the storage unit 220, generates DR information that is information to be communicated to each consumer (each facility such as the houses 20a to 20c) regarding the DR command, and the terminal of each facility It has a function of transmitting DR information to the device 100a or the like via the network 11. The transmission unit 240 is realized by the processor 202 that executes the control program stored in the memory 201 and the communication interface 203. In response to the transmission instruction related to the DR command of the electric power company or DR aggregator, the transmission unit 240 includes the DR information so as to include the DR period, the target number of houses, the target reduction amount, and the privilege information in the DR management information (see FIG. 5). It is generated and transmitted to the terminal devices 100a to 100c and the like. Each time the DR management information is updated thereafter, the transmission unit 240 generates DR information so as to include the DR period, the number of target eaves, the target reduction amount, the number of group reduction eaves, the group reduction amount, and privilege information, and the terminal device It transmits to 100a-100c etc. FIG. 6 shows an example of DR information when the number of group reduction eaves and the group reduction amount are included. As shown in the figure, the DR information includes a DR period, group reduction schedule information, and privilege information. This group reduction schedule information is information relating to the amount of reduction in power usage during the DR period for a group of customers (facility) that is the target of the DR command. For example, the number of target eaves, the target reduction amount, the number of group reduction eaves, the group reduction Consists of quantities, etc. Note that the transmission unit 240 may transmit the DR information at regular intervals or at predetermined times instead of transmitting the DR information every time the DR management information is updated. Transmission of DR information is repeatedly performed before the DR period. Since the DR information transmitted by the transmission unit 240 is received and displayed in the terminal device 100a or the like, the resident of the house 20a can know the status of cooperation plans for DR commands in other houses.

(Operation)
Hereinafter, an operation example of the DR information system 10 having the above-described configuration (information processing method in the DR information system 10) will be described.

  FIG. 7 is a flowchart showing the operation of the server device 200. Hereinafter, the operation of the server apparatus 200 will be described with reference to FIG.

  The server device 200 acquires information (DR period, target number of houses, target reduction amount) related to the DR command from the power company or the DR aggregator via the input device or the communication interface, and acquired as DR management information in the storage unit 220. Information is recorded (step S11). In addition, when there is privilege information related to a privilege when the DR target can be achieved as information related to the DR command, the privilege information is also recorded as DR management information. The privilege is, for example, a discount on an electric charge, a discount on a product, or the like, and may be anything else.

  Next, the server device 200 generates DR information including the contents of the DR management information recorded in the storage unit 220, and transmits the DR information to each terminal device (terminal devices 100a to 100c, etc.) by the transmission unit 240. (Step S12).

  The server device 200 can receive the reduction schedule information from the terminal devices 100a to 100c and the like as needed. When the reception unit 210 receives the reduction schedule information (step S13), the reception unit 210 stores the reduction schedule information in the storage unit 220. The specifying unit 230 refers to the reduction amount specifying information according to one or more reduction schedule information already stored in the storage unit 220, and uses the power during the DR period for the entire group of facilities subject to the DR command. The amount of reduction is specified (step S14). The identifying unit 230 calculates the number of group reduction eaves by calculating the number of terminal devices that have transmitted reduction schedule information indicating that there is a reduction amount (that the reduction amount is not zero) among the reduction schedule information in the storage unit 220.

Then, the DR management information in the storage unit 220 is updated based on the specified number of group reduction houses and the reduction amount (group reduction amount) specified in step S14 (step S15).

  Subsequently, the server device 200 generates DR information including the content of the DR management information by the transmission unit 240 and transmits the DR information to each terminal device (terminal devices 100a to 100c, etc.) (step S16). The server apparatus 200 repeats Steps S13 to S16 until a time point that is a predetermined period T1 (for example, 1 hour) before the DR period (for example, the start time of the DR period) (Step S17).

  The server apparatus 200 outputs the DR management information recorded in the storage unit 220 when the time point T1 before the DR period elapses (step S18). This output is performed, for example, by displaying on the display 205 or transmitting to an external device operated by the power company or DR aggregator. From this output, for example, the power company or the DR aggregator can know the reduction amount of the power usage that is reduced by the cooperation of the customer in response to the request for the reduction of the power usage as the DR command.

  FIG. 8 is a flowchart showing the operation of the terminal device 100a of the house 20a. Hereinafter, the operation (information processing method) in the terminal device 100a will be described with reference to FIG.

  When receiving the DR information from the server device 200 by the receiving unit 110 (step S21), the terminal device 100a operating in cooperation with the server device 200 described above displays a screen on the touch panel 104 or the like based on the DR information by the display unit 120. (Step S22).

  Based on the DR information transmitted in step S12 (FIG. 7) in the server device 200, in step S22, the DR period, the target number of houses, the target reduction amount, and the like are displayed on the screen. The display of the DR period, the target number of houses, and the like may be performed by dividing the display into a plurality of screens that are changed by the operation of the user (resident of the house 20a). Although omitted in FIG. 8, the display unit 120 can perform display control related to screen transition. This step S22 is repeated every time DR information is received from the server device 200 before the DR period starts. Then, the display on the screen is updated based on the DR information including the number of group reduction eaves and the group reduction amount shown in FIG. The display of the screen based on the group reduction schedule information (the number of group reduction houses, etc.) in the DR information is realized, for example, by displaying a character string, a symbol, a figure, a graph or the like for representing the group reduction schedule information on a display or the like. . FIG. 9 shows a screen example displayed on the touch panel 104 in step S22. In the figure, a plurality of screens (screens 31 to 35) that are targets of screen transitions according to user operations are illustrated. Here, the description of the operation of the terminal device 100a according to FIG. 8 is interrupted, and the screens 31 to 35 in FIG. 9 will be described. Each screen includes GUI components such as character strings, buttons, and check boxes that constitute a graphical user interface (GUI).

  The display unit 120 performs a display on the screen 31 indicating that an answer is requested as to whether or not to reduce power use in the facility (house) during the DR period. The screen 31 is a DR screen as a main screen for displaying DR information, and includes a message indicating a DR period and requesting cooperation for reducing power usage. Further, the screen 31 has a button 31b drawn as “cooperate” to be pressed when the user cooperates to reduce power consumption, and a button 31c drawn as “do not cooperate” to press when the user does not cooperate. , And a button 31a for screen transition. When the button 31a is pressed, the cooperation status of other customers (for example, a group of several hundreds of houses in one area) targeted for the DR command (ie, the status of planned cooperation for power saving in the DR period) is known. Operation. When the user presses the button 31a on the screen 31 (touch operation on the touch panel 104), the screen 32 is displayed.

  The screen 32 is a screen that displays the cooperation status of the consumer group (a group of houses in one area) to the DR command. The screen 32 includes a button 32 a for transitioning to the screen 31. On the screen 32, the target number and target reduction amount of DR information are displayed as "target number of houses" and "target reduction amount", respectively, and the number of group reduction houses of DR information is displayed as "number of cooperation houses", and the group information reduction of DR information The amount is displayed as “expected reduction amount”, the ratio (ratio) of the DR information group reduction number to the target number of houses is displayed as “cooperation status”, and the privilege information of DR information is displayed as “target achievement privilege” . The display unit 120 may calculate the ratio (ratio) of the number of group reduction eaves of DR information to the target number of eaves, or the server device 200 may transmit the calculation result of the ratio included in the group reduction plan information in advance. . This screen 32 is useful as a material for determining whether or not to cooperate in reducing power consumption. By viewing the screen 32, the user can appropriately determine whether or not to cooperate in reducing power usage. For example, in a situation where the cooperation status displayed on the screen 32 is 99%, and the number of cooperation houses is less than the target number of houses, the user (resident of the house 20a) cooperates to obtain a privilege. May be determined to be good. Further, in a situation where the cooperation status displayed on the screen 32 is 110%, the user does not need to cooperate in particular, and thus, for example, the user does not cooperate with the current DR command (request for reduction of power usage). Can be determined. The display unit 120 of the terminal device 100a performs control so that the screen displayed before the display of the screen 32 can be returned to when the user presses the button 32a after confirming the screen 32.

  When the user presses the button 31 b on the screen 31, the display unit 120 displays a screen 33 representing a cooperative state. The screen 33 includes a button 33a for screen transition to the screen 32, a button 33c for screen transition to the screen 35 for inputting device control content (power saving content) for reducing power consumption, A screen transition button 33b for returning to the screen 31 to change the determination result is included.

  When the user presses the button 31 c on the screen 31, the display unit 120 displays a screen 34 that represents a state in which the user does not cooperate. The screen 34 includes a button 34a for screen transition to the screen 32 and a button 34b for screen transition for returning to the screen 31 in order to change the determination result indicating that the cooperation is not performed.

  When the user presses the button 33c on the screen 33, the display unit 120 displays a screen 35 for inputting device control content as power saving content. The display unit 120 displays a screen 35 indicating that the content of device control for reducing the power usage in the facility (house) is requested during the DR period. The screen 35 includes a screen transition button 35 a for completing the input of power saving content and returning to the screen 33. The screen 35 may also include a button for transitioning to the next screen when there are one or more items (check boxes or the like) for receiving device control content as power saving content, for example. The item for receiving the contents of device control by the check box is to select various kinds of predetermined devices and the control content for each device. This screen 35 is configured such that in response to a check box operation by the user, the receiving unit 130 of the terminal device 100a can receive the operation and generate reduction schedule information (FIG. 3).

  Hereinafter, it returns to description of operation | movement of the terminal device 100a according to FIG. In step S22, after the display unit 120 of the terminal device 100a displays a screen based on the DR information, a user operation is accepted.

  When a user operation is received (step S24) before a certain period T2 (for example, several hours) before the DR period (for example, the start time of the DR period) (step S23), the receiving unit 130 performs the operation. Accordingly, reduction schedule information (see FIG. 3) is generated (step S25). This user operation is, for example, an operation of the input completion button 35a in the screen example of FIG. Subsequent to step S25, the transmission unit 150 of the terminal device 100a transmits the reduction schedule information generated by the reception unit 130 to the server device 200 via the network 11 (step S26). Note that the terminal device 100a generates the reduction schedule information and transmits it to the server device 200 only when the user performs an operation of cooperating with the DR command when the reduction schedule information has not been transmitted yet. May be. In this case, after the reduction schedule information is once transmitted, the reduction schedule information is generated and transmitted to the server device 200 when the content differs from the previous time regarding whether or not to cooperate in accordance with a user operation. To do. Further, when the user performs an operation of not cooperating when the reduction schedule information has not yet been transmitted, the reduction schedule information having contents indicating that there is no reduction amount (zero) is generated and stored in the server apparatus 200. It is good also as transmitting.

  In the terminal device 100a, steps S21 to S26 are repeated until the DR period based on the DR information is started (step S27). Accordingly, the terminal device 100a can transmit the reduction schedule information to the server device 200 in accordance with a user operation until a certain period T2 before the DR period. In addition, before the DR period, the terminal device 100a displays the cooperation status for reducing power usage based on the DR information transmitted from the server device 200 as needed. When the DR period starts (step S27), the output unit 140 of the terminal device 100a outputs a control signal corresponding to the content of device control based on the reduction schedule information already generated by the receiving unit 130 (step S28). The power usage can be suppressed by controlling the device 21 and the like. When the device to be controlled has an operation reservation function, the output unit 140 may reserve the operation in the DR period by transmitting a control signal to the device before the start of the DR period.

  FIG. 10 is a diagram illustrating a specific example of a communication sequence between devices in the DR information system 10. Hereinafter, the cooperative operation of the terminal device 100a to 100c in the server device 200 and each of the houses 20a to 20c will be described with reference to FIG. As a premise of the example of FIG. 5, the terminal devices 100 a to 100 c generate the reduction schedule information only when the user performs an operation to cooperate with the DR command when the reduction schedule information has not yet been transmitted. Then, a method of transmitting to the server device 200 is assumed. That is, the terminal devices 100a to 100c omit the transmission of the reduction schedule information when the user does not cooperate with the request for reduction of the power usage related to the DR command and the reduction schedule information has not been transmitted yet. Here, it is assumed that the reduction schedule information indicating that cooperation is performed includes the contents of device control input on the screen 35.

  First, server device 200 transmits DR information including a DR period, a target number of houses, a target reduction amount, privilege information, and the like to each terminal device 100a to 100c (sequence S1001). The transmission of DR information to each of the terminal devices 100a to 100c does not necessarily have to be performed simultaneously.

  In the example of FIG. 10, when a resident or the like of the house 20 c first operates the terminal device 100 c to indicate that the DR command cooperates in reducing power usage, the reduction schedule information is transmitted from the terminal device 100 c to the server device 200. (Sequence S1002). The server apparatus 200 identifies the number of group reduction eaves and the group reduction amount according to the reduction schedule information, updates the DR management information (see FIG. 5), and updates the DR information based on the DR management information (see FIG. 6). Is transmitted to each of the terminal devices 100a to 100c (sequence S1003). Thereby, the residents of the homes 20a to 20c can know the status of cooperation with the DR command in other homes and the like on the screens displayed on the terminal devices 100a to 100c based on the DR information. Thereby, the resident of each house can appropriately determine whether or not to cooperate in power saving in the DR period.

  Here, the reduction schedule information is transmitted from the terminal device 100b of the house 20b to the server device 200 (sequence S1004). The server device 200 again determines the number of group reduction eaves and the group reduction amount, updates the DR management information, and transmits DR information indicating the latest cooperation status in the group such as a house to each of the terminal devices 100a to 100c (sequence S1005). ).

  After that, similarly, when the reduction schedule information is transmitted from the terminal device 100a of the house 20a to the server device 200 (sequence S1006), the server device 200 again specifies the number of group reduction eaves and the group reduction amount, and sets the DR management information. Update. Then, the server device 200 transmits DR information indicating the latest cooperation status in a group such as a house to each of the terminal devices 100a to 100c (sequence S1007). For example, it is useful to transmit DR information (group reduction schedule information, etc.) reflecting the contents even when the reduction schedule information is received from all the terminal devices of the group of facilities subject to the DR command. . This is because there is room to change whether or not the person (resident, etc.) of each facility cooperates by knowing the DR information.

  In the terminal device 100b of the house 20b, a screen is displayed based on the DR information indicating the latest cooperation status. For example, a resident of the house 20b changes the judgment to not cooperate and operates the terminal device 100b. As a result, the reduction schedule information indicating that the terminal apparatus 100b does not cooperate (that there is no reduction amount) is generated and transmitted to the server apparatus 200 (sequence S1008). Upon receiving this reduction schedule information, the server apparatus 200 again identifies the number of group reduction eaves and the group reduction amount, updates the DR management information, and provides DR information indicating the latest cooperation status in the group such as a house as the terminal apparatuses 100a to 100a. 100c is transmitted (sequence S1009).

  As described above, according to the DR information system 10, the current cooperation status with respect to the DR command is displayed in the group of houses in the same region in the terminal devices 100a to 100c of the houses 20a to 20c (see FIG. 9, screen 32). ). Therefore, there is a high possibility that residents in each house can determine whether or not to cooperate appropriately.

(Other embodiments, etc.)
As mentioned above, although DR information system 10 was explained by Embodiment 1, it cannot be overemphasized that embodiment mentioned above is only an example, and various change, addition, omission, etc. are possible.

  In the above-described embodiment, the example of the reduction schedule information transmitted from the terminal device 100a to the server device 200 includes the content of device control used for specifying the reduction amount of power use. However, the reduction amount information includes a numerical value of the reduction amount. It is good as well. For the numerical value of this reduction, for example, the HEMS controller accumulates the results of measuring the power used by the current sensor for each branch circuit that causes the distribution board to branch the power from the power system to each part in the house by HEMS of the house 20a. Then, it can be calculated by performing statistical processing (average etc.). When the user performs a branch circuit designation operation for reducing power usage during the DR period in order to save power in response to the DR command, the terminal device 100a uses normal power consumption (for all the designated branch circuits ( The total of the average value etc.) can be included in the reduction schedule information as a reduction amount. In addition, the terminal device 100a transmits the reduction schedule information generated by the reception unit 130 in response to the operation on the touch panel 104 to the server device 200, but generates the reduction schedule information without receiving such a direct operation. May be. For example, when the terminal device 100a communicates with the HEMS device, the reception unit 130 receives information indicating a setting state set by the user with respect to the HEMS device such as an air conditioner (for example, reservation is made so as to suppress the set temperature by 1 ° C. during the DR period). The reduction schedule information may be determined from the acquired information. In this case, the user can change the setting for the HEMS device by observing the cooperation status of residents of other houses displayed as the DR information, determining whether to cooperate with the DR command, or not. Note that the reduction schedule information transmitted from the terminal device 100a to the server device 200 may be information related to the amount of reduction in power usage in the facility during the DR period, for example, information that only distinguishes whether the amount of reduction is zero or not zero. (That is, information indicating whether or not to cooperate in power saving).

  In the above-described embodiment, the houses 20a to 20c in one area are shown as an example of a group of a plurality of facilities (a group of consumers) that are requested to suppress power use (power saving) by the DR command. The facility is not limited to housing. For example, the facilities are public facilities, offices, research laboratories, factories, stadiums, stations, and other various buildings and structures that use electric power. In addition, the range of a group of a plurality of facilities that are subject to a DR command may be determined as a geographical range, for example, because it is related to the range of power supplied by an electric power company. For example, a group of a plurality of facilities (houses, etc.) that are subject to the DR command may be included in a predetermined area range that is somewhat narrow, such as the same municipality, the same school district, or several hundred meters square. In this case, each resident of each house knows, for example, the status of cooperation of inhabitants who are familiar with the DR information system, and determines whether or not to cooperate in power saving based on a sense of solidarity (community consciousness) due to interdependence. Can be judged. However, a group of a plurality of facilities subject to the DR command does not necessarily belong to the same area.

  In addition, the display unit 120 of the terminal device 100a described in the above embodiment displays a screen on the display of the touch panel 104, but the display on the terminal device 100a is not necessarily displayed. For example, the display unit 120 of the terminal device 100a may be controlled to display information on the display device by outputting information to be displayed to an external display device such as a tablet that can communicate with the terminal device 100a. Further, the screen may be displayed by a projector or the like instead of the display.

  Further, although the terminal device 100a described in the above embodiment includes the touch panel 104 that can display and input, a display that performs display and an input device such as a keyboard and a pointing device that perform input are separated. You may do it.

  Further, the terminal devices 100a to 100c and the like shown in the above-described embodiments are devices having a function as a HEMS controller installed in a house 20a or the like of a person who has previously made a contract with a power company or a DR aggregator. However, it may not be a HEMS controller. In addition, the terminal devices 100a to 100c and the like do not necessarily have to be installed in a facility (such as a house). For example, a portable device such as a smartphone (tablet or the like) owned by a person (such as a resident) of the facility. Terminal). That is, a terminal device of a certain facility (such as a house) can transmit reduction schedule information related to the reduction in power usage during the DR period at the facility to the server device by having some relationship with the facility. Any device can be used as long as it can receive the signal.

  In addition, in the terminal device 100a shown in the above-described embodiment, the output unit 140 may not be provided. When the user performs an input operation for cooperating with power saving in the DR period, for example, in the DR period. You may save electricity by operating the device 21 or the like.

  Further, the group reduction schedule information (see FIG. 6) transmitted from the server device 200 to each of the terminal devices 100a to 100c and the like shown in the above-described embodiment includes the target number of houses, the target reduction amount, the number of group reduction houses, and the group reduction. The amount was included. However, the target number of houses and the target reduction amount are merely examples of the target quantities for reducing the power usage during the DR period. In addition, the target quantity may not necessarily be included in the group reduction schedule information. In addition to the group reduction schedule information, the target regarding the DR command may be informed to the residents or the like by transmission, broadcasting, distribution, or other methods. The group reduction schedule information may be information that reflects the reduction schedule information received from the terminal device and represents the status of the cooperation schedule for power saving in the DR period in the group of facilities. The group reduction schedule information is, for example, the entire number of facilities specified based on the reduction target information received from the terminal device and the quantity targeted for the reduction of power usage in the entire facilities targeted by the DR command. It is the information which shows the relationship with the quantity regarding the reduction | decrease of electric power use of. Note that the information indicating the relationship between the quantity and the quantity may be information that can be used to explicitly display both quantities, or by replacing the quantity with length, area, or other information in a graph or the like. It may be information that can be used for display. The ratio of the number of group reduction eaves to the target number of eaves exemplified as “cooperation status” on the screen 32 in FIG. 9 may be displayed as a pie chart or other graphic in addition to a numerical value. The display unit 120 may display the ratio of the group reduction amount to the target reduction amount on the screen as “cooperation status”, for example.

  Further, the execution order of the operation procedures of the terminal device 100a and the server device 200 (see FIGS. 7 and 8) is not necessarily limited to the order described above, and does not depart from the gist of the invention. The execution order can be changed or a part thereof can be omitted. In addition, all or part of the above-described operation procedure may be realized by hardware of the terminal device 100a, the server device 200, or another device, or may be realized by using software. The processing by software is realized by a processor included in the terminal device 100a and the server device 200 executing a control program stored in the memory. Further, the program may be recorded on a recording medium and distributed or distributed. For example, by installing the distributed control program in the apparatus and causing the processor of the apparatus to execute the control program, the apparatus can perform all or part of the operation (information processing) of the terminal device 100a described above. Become.

  In addition, embodiments realized by arbitrarily combining the constituent elements and functions described in the above-described embodiments are also included in the scope of the present invention.

  Note that various general or specific aspects of the present invention include one or a plurality of combinations of an apparatus, a system, a method, an integrated circuit, a computer program, a computer-readable recording medium, and the like.

  Hereinafter, a DR information system according to an aspect of the present invention, and a terminal device, an information processing method, and a configuration of a control program related to the DR information system, modification modes, effects, and the like are described.

  (1) A DR information system 10 according to an aspect of the present invention is a DR information system including a server device 200 and terminal devices 100a to 100c of a plurality of facilities (housings 20a to 20c). And a reduction amount of power usage in the facility in a predetermined future DR period (one DR period defined for requesting reduction of power usage by the DR command) from the terminal devices 100a to 100c of each of the plurality of facilities. The server receiving unit 210 that receives the reduction schedule information, and the power usage in the predetermined DR period in the entire plurality of facilities specified based on the reduction schedule information received from the one or more terminal devices by the server reception unit 210 A group transmission schedule information indicating the quantity related to reduction is transmitted to the terminal devices 100a to 100c of each of the plurality of facilities. The terminal device 100a to 100c includes a transmission unit 240, and the terminal devices 100a to 100c receive the group reduction schedule information, and perform display based on the group reduction schedule information received by the terminal reception unit 110 before a predetermined DR period. It includes a display unit 120 and a terminal transmission unit 150 that transmits the reduction schedule information to the server device 200 before a predetermined DR period. Here, the plurality of facilities are a group of facilities (a group of customers) as a unit that is a target of the DR command.

  With this configuration, the terminal devices 100a to 100c in the homes 20a to 20c provide a display useful for determining whether or not to cooperate with a request for reduction of power usage. Therefore, the resident can appropriately determine by checking the display. .

  (2) For example, the plurality of facilities are located within a predetermined area range, and the server transmission unit 240 sets the target quantity and the reduction schedule information for the reduction of power usage in the predetermined DR period for the plurality of facilities as a whole. The group reduction schedule information indicating the relationship with the quantity related to the reduction of power usage in the predetermined DR period in the plurality of facilities specified based on the base station is transmitted, and the terminal devices 100a to 100c further display at least the display by the display unit 120. Later, it is provided with a reception unit 130 that receives an operation and determines reduction schedule information according to the received operation, and the terminal transmission unit 150 transmits the reduction schedule information determined by the reception unit 130 to the server device 200. Also good.

  Thereby, since the status of power saving cooperation in each facility with respect to the power saving target in the area can be displayed on the terminal devices 100a to 100c, each resident in the houses 20a to 20c is willing to achieve the target together with other residents in the same area. It will be possible to properly determine whether or not to cooperate in saving electricity. In addition, the display on the terminal devices 100a to 100c promotes the cooperation of local residents, for example, and for a power company or a DR aggregator that requests cooperation for power saving with a DR command, the set target may be achieved. The effect of increasing can occur.

  (3) For example, the display unit 120 in the facility terminal device 100a performs a display indicating that an answer to request whether or not to reduce power usage in the facility is requested during a predetermined DR period, and the facility terminal device 100a In response to the operation, the receiving unit 130 determines reduction schedule information so as to distinguish whether the amount of reduction in power usage at the facility is zero or not, and the server transmission unit 240 determines whether or not the plurality of facilities as a whole. The number of facilities that reduce power usage and the number of facilities whose power usage reduction amount is not zero in the predetermined DR period specified based on the planned reduction information are targets for reducing power usage in the predetermined DR period. The group reduction schedule information indicating the relationship may be transmitted.

  Thereby, for example, the resident of each house can confirm with the terminal device whether to cooperate in power saving in the DR period or how many houses, and can appropriately determine whether or not to cooperate in power saving.

  (4) For example, the server transmission unit 240 has a target power consumption reduction amount in the predetermined DR period specified based on the reduction schedule information with respect to the number of facilities that reduce power usage in the predetermined DR period is not zero. It is good also as transmitting the group reduction plan information which shows the ratio of the number of facilities.

  As a result, by confirming whether or not the target is achieved by the display of each terminal device, the user of the terminal device (resident of each house, etc.) appropriately determines whether or not to cooperate in power saving. Can be judged.

  (5) For example, the display unit 120 in the facility terminal device 100a performs a display indicating that the content of device control for reducing power usage in the facility is requested during a predetermined DR period, and the facility terminal device 100a. In the case where the reduction plan information is determined so as to indicate that the amount of reduction in power consumption at the facility is not zero, the reception unit 130 determines the reduction plan information including the contents of device control according to the operation, and the server device 200 includes a specifying unit 230 that specifies a reduction amount of power usage in a plurality of facilities in a predetermined DR period according to the content of device control in the reduction schedule information, and the server transmission unit 240 is specified by the specifying unit 230. It is also possible to transmit group reduction schedule information that further indicates the amount of reduction that has been performed.

  Thereby, the user can confirm the reduction amount of the power usage in the predetermined DR period in the group of facilities, and can appropriately respond to the DR command based on the reduction amount. In addition, the server apparatus estimates the amount of reduction in power usage during the DR period, and can be used for planning, for example, a DR aggregator.

  (6) For example, the display unit 120 in the terminal device 100a of the facility performs a display indicating that the content of device control for reducing power usage in the facility is requested during a predetermined DR period. The reduction schedule information including the contents of the device control is determined according to the operation, and the server apparatus 200 reduces the power usage in the predetermined DR period for the entire plurality of facilities according to the contents of the device control in the reduction schedule information. The server transmitting unit 240 includes an identifying unit 230 that identifies the amount, and the server transmitting unit 240 identifies the amount of reduction in power usage, which is a target for reducing power usage in a predetermined DR period across the plurality of facilities, and is identified by the identifying unit 230 The group reduction schedule information indicating the relationship with the reduction amount may be transmitted.

  Thereby, the user can confirm the relationship between the reduction amount of power usage and the target reduction amount in a predetermined DR period in the group of facilities, and can appropriately respond to the DR command based on the relationship. Become.

  (7) For example, the terminal device 100a may further include an output unit 140 that outputs a control signal for device control in a predetermined DR period in response to an operation received by the receiving unit 130.

  Thereby, for example, when the user decides to cooperate in power saving in the predetermined DR period and performs an operation, the apparatus can be controlled and power saving can be executed without performing any special operation in the predetermined DR period.

  (8) For example, the server transmission unit 240 further displays privilege information related to a privilege provided when a reduction target of power use in a predetermined DR period in the plurality of facilities is achieved for each of the plurality of facilities. The terminal receiving unit 110 may further receive privilege information, and the display unit 120 may further display the privilege information when displaying based on the group reduction schedule information.

  Thereby, for example, the user can check the privilege information and the cooperation status of other residents for power saving, and can appropriately determine whether or not to cooperate in power saving.

  (9) For example, the quantity relating to the reduction of power usage in the plurality of facilities as a whole is specified at a plurality of timings, and the server transmission unit 240 is specified every time the specification is performed before a predetermined DR period. It is also possible to transmit the group reduction schedule information indicating the quantity that has been determined.

  As a result, the user can confirm the status of cooperation that sequentially changes in the group of facilities, and therefore can appropriately determine whether or not to cooperate in power saving.

  (10) A terminal device according to an aspect of the present invention is a single terminal device 100a used in the DR information system 10 including the server device 200 and the terminal devices 100a to 100c of a plurality of facilities (housing 20a to 20c). And a target quantity for reducing power usage in a predetermined future DR period across the plurality of facilities and specified based on information received from one or more terminal devices in the DR information system 10 The reception unit 110 that receives the group reduction schedule information that indicates the relationship with the quantity related to the reduction of power usage during the predetermined DR period in the plurality of facilities as a whole, and the group reduction received by the reception unit 110 The display unit 120 that performs display based on the schedule information before the predetermined DR period, and at least after the display by the display unit 120, the operation is performed.
