JP 2014-120028 A

  For example, a business operator who has requested DR to a plurality of power consumers estimates how much power consumption can be reduced based on a response from each power consumer whether or not to respond to the request. Then, when it is determined that it is necessary to reduce a larger amount of power, the business operator may make a new DR request to a power consumer who has not yet requested DR.

  By the way, a power consumer may have introduced a dedicated terminal device that automatically performs the above-described response in its own power demand facility. For example, when the dedicated terminal device receives a request for DR from the above-mentioned business operator, the dedicated terminal device can immediately make the above-described response based on the settings registered in advance. Then, the dedicated terminal device that has responded to the request of the DR automatically controls the electrical equipment in its own power demand facility, thereby reducing the power consumption in its own power demand facility.

  On the other hand, since the electric power consumer who has not introduced such a dedicated terminal device performs the response by e-mail or FAX, it takes time until the response is made after the operator requests DR There is.

  As described above, in an environment in which there is a variation in time from when a request for DR is made to a plurality of power consumers until a response is made as to whether or not the request is satisfied, a technology that more reliably satisfies the demand for power consumption. Is required.

  The present invention has been made to solve the above-described problems, and its purpose is to make a response regarding whether or not to respond to the request after making a request for power consumption to a plurality of request destinations.

A program for causing a setting unit to function as a notification unit that notifies the terminal device of the request according to the notification timing set by the setting unit.

  The present invention can be realized not only as a power consumption management apparatus including such a characteristic processing unit, but also as a method using such characteristic processing as a step. Further, it can be realized as a semiconductor integrated circuit that realizes part or all of the power consumption management device, or can be realized as a system including the power consumption management device.

  According to the present invention, it is possible to more reliably request power consumption in an environment in which there is a variation in the time from when a request for power consumption is made to a plurality of request destinations until a response indicating whether to respond to the request is received. Can be satisfied.

FIG. 4 is a diagram showing a sequence of power consumption management processing in the power consumption management system according to the embodiment of the present invention. FIG. 5 is a diagram showing a configuration of the power consumption management apparatus according to the embodiment of the present invention.

  First, the contents of the embodiment of the present invention will be listed and described.

  (1) The power consumption management device according to the embodiment of the present invention is based on a response time from notification of a request regarding power consumption to a corresponding terminal device until acquisition of a response regarding whether to respond to the request. For a plurality of classified load groups, a setting unit that sets different notification timings for each of the load groups as the notification timing of the request, and notifies the terminal device of the request according to the notification timing set by the setting unit A notification unit.

  With this configuration, when making a request for power consumption, it is possible to appropriately determine for each load group at what timing before the target period the request should be made, and to make the request at the determined timing. it can. Therefore, it is possible to more reliably satisfy the power consumption request in an environment where there is a variation in the time from when a request for power consumption is made to a plurality of request destinations until a response indicating whether or not to respond to the request is received. .

(2) Preferably, the power consumption management device further includes:
A request unit that determines the content of the new request to the other load group based on the content estimated by the response from the load group.

  With such a configuration, it is possible to determine the content of the request to the load group to be requested next based on the content of the response from the load group that has previously requested. Can be satisfied more reliably.

  (3) Preferably, the setting unit sets the notification timing earlier for the load group having a large response time than the load group having a small response time.

  With such a configuration, it is possible to make a request to a load group having a slow response early, so that, for example, more responses can be acquired before the start of the request target period.

  (4) Preferably, the said setting part sets the said notification timing late | slow to the said load group with the said small response time compared with the said load group with the said large response time.

  With such a configuration, it is possible to make a request to a load group having a slow response early, so that, for example, more responses can be acquired before the start of the request target period.

  (5) Preferably, the load group is classified based on the response time and a record according to the request.

  With such a configuration, the load group can be classified more appropriately.

  (6) Preferably, the said setting part sets the said notification timing early to the load group with the said low result compared with the said load group with the said high result.

  With such a configuration, for example, after confirming the content of a response from a load group that is unlikely to respond to the request, it is possible to determine the content of the request to the load group that is highly likely to respond to the request. The overall demand for power consumption can be met more reliably.

  (7) Preferably, the said setting part sets the said notification timing late | slow to the load group with the said high track record compared with the said load group with the said low track record.

  With such a configuration, for example, after confirming the content of a response from a load group that is unlikely to respond to the request, it is possible to determine the content of the request to the load group that is highly likely to respond to the request. The overall demand for power consumption can be met more reliably.

  With such a configuration, an appropriate notification timing can be set for each group of power consumers.

  (9) Preferably, the plurality of load groups include an automatic response group that automatically responds to the request and a group that does not automatically respond to the request.

  With such a configuration, for example, each power consumer can be appropriately classified in an environment in which a power consumer having a device that automatically responds to a request and a power consumer not having the device are mixed. .

  (10) More preferably, the setting unit sets the latest notification timing in the automatic response group among the plurality of groups.

  With such a configuration, for example, since it is possible to make a request to another load group having a slow response earlier than an automatic response group having a fast response, more responses can be obtained before the start of the target period of the request. it can.

  (11) More preferably, the notification unit sends a request based on a difference between an overall request regarding the power consumption and a content estimated by the response from the load group other than the automatic response group to the automatic response group. To the terminal device corresponding to.

  With such a configuration, for example, it is difficult to expect the implementation of the requested content and quick response, but a large number of other load groups can satisfy the request to some extent, and the reliable implementation of the requested content and early response can be expected. A certain automatic response group can perform excellent power management to satisfy the shortage. In addition, the request to the automatic response group can be used as an adjustment to satisfy the overall request.

  (12) More preferably, the power consumption management device further includes a price calculation unit that calculates a price for responding to the request, and the price calculation unit compares the automatic response with the other load groups. The consideration of the group is calculated high.

  With such a configuration, for example, it is possible to encourage power consumers belonging to groups other than the automatic response group to introduce a device that automatically responds to a request.

  (13) Preferably, the power consumption management device further includes a classification unit that classifies the device or the power consumer into any of the plurality of load groups, and the classification unit does not obtain the response time. A device or a power consumer is classified into the load group with the earliest notification timing.

  With such a configuration, for example, a response from a device or a power consumer for which no response time has been obtained in the past can be reliably acquired until the start of the request target period.

  (14) A power consumption management program according to an embodiment of the present invention is a power consumption management program used in a power consumption management device, wherein the computer notifies a corresponding terminal device of a request regarding power consumption and A setting unit configured to set a different notification timing for each load group as the notification timing of the request for a plurality of load groups classified based on response time until obtaining a response regarding whether to respond to the request; and the setting unit Is a program for causing the terminal device to function as a notification unit that notifies the terminal device of the request according to the notification timing set by.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated. Moreover, you may combine arbitrarily at least one part of embodiment described below.

  FIG. 1 is a diagram for explaining an outline of a power consumption management system according to an embodiment of the present invention.

  The retailer 1 is, for example, a power retailer. The retailer 1 makes a request for DR, that is, a request for suppressing power consumption, to the aggregator 2 that is a business that manages each customer 4 with respect to DR. When the aggregator 2 receives a request for DR from the retail business apparatus 11, the aggregator 2 makes a request for DR to each customer 4, which is a power demand that has a contractual relationship with itself.

  The retailer 1 makes a DR request to the aggregator 2 by specifying the total amount of power consumption to be reduced by each consumer 4. Hereinafter, the total amount designated by the retailer 1 is also referred to as a reduction designated total amount G.

  The aggregator 2 that has received a DR request from the retailer 1 designates the amount of power to be reduced and makes a DR request to each consumer 4. Hereinafter, the power consumption amount designated by the aggregator 2 is also referred to as a reduction designated amount I.

  For example, the aggregator 2 allocates the reduction designated total amount G to each customer 4 to determine the power consumption amount, that is, the reduction designated amount I that each of the consumers 4 should reduce.

  FIG. 2 is a diagram showing the configuration of the power consumption management system according to the embodiment of the present invention.

  With reference to FIG. 2, the power consumption management system 101 includes a retail business device 11, a power consumption management device 12, a plurality of devices 13, a plurality of general-purpose terminal devices 14, and a plurality of dedicated terminal devices 15. .

  The retail business apparatus 11 is a server operated by the retail business operator 1, for example. The power consumption management device 12 is a server operated by the aggregator 2, for example. The retail business apparatus 11 is connected to the power consumption management apparatus 12 via the network 8.

  The retailer 1 makes a DR request to the aggregator 2 by transmitting an overall DR request from the retail business device 11 to the power consumption management device 12. The overall DR request is, for example, information indicating a DR target period and a reduction designated total amount G.

  The power consumption management device 12 is connected to the general-purpose terminal device 14 and the dedicated terminal device 15 via the network 8.

  For example, the customer 4 includes a customer 4 who has installed the dedicated terminal device 15 in his own power demanding facility 3 and a customer 4 who has not installed the dedicated terminal device 15 in his own power demanding facility 3. Exists. The general-purpose terminal device 14 is a communication terminal device such as a smartphone or a tablet, for example. The dedicated terminal device 15 is, for example, a gateway device in HEMS (Home Energy Management System).

  The aggregator 2 makes a DR request to each consumer 4 by transmitting an individual DR request from the power consumption management device 12 to the general-purpose terminal device 14 or the dedicated terminal device 15 corresponding to each consumer 4. The individual DR request is, for example, information indicating a DR target period and a reduction designated amount I.

  The customer 4 who has installed the dedicated terminal device 15 in his own power demand facility 3 receives the individual DR request from the power consumption management device 12 in the dedicated terminal device 15. The dedicated terminal device 15 is connected to a device 13 such as an air conditioner or a lighting device in the power demand facility 3 by wire or wirelessly. When the dedicated terminal device 15 receives the individual DR request, for example, based on the content set in advance by the customer 4, for example, an individual DR response indicating whether or not to comply with the content of the individual DR request is immediately managed for power consumption. Automatically transmitted to the device 12. Hereinafter, following the DR request is also referred to as “participating in DR”.

  When the dedicated terminal device 15 transmits the individual DR response to participate in the DR, the dedicated terminal device 15 controls each device 13 based on the content of the individual DR request, so that the amount of power consumed in the power demanding facility 3, that is, the customer 4 Reduce power consumption.

  The customer 4 who does not install the dedicated terminal device 15 in his / her power demand facility 3 receives the individual DR request from the power consumption management device 12 in the general-purpose terminal device 14 such as a smartphone or a tablet. For example, when the content of the individual DR request displayed on the display of the general-purpose terminal device 14 is confirmed, the customer 4 determines whether to comply with the content of the individual DR request, that is, whether to participate in the DR, and the determination result Is input to the general-purpose terminal device 14.

  When the general-purpose terminal device 14 receives an input operation from the customer 4, the general-purpose terminal device 14 transmits an individual DR response indicating whether or not to participate in DR to the power consumption management device 12. For example, the consumer 4 that has transmitted the individual DR response to participate in the DR from the general-purpose terminal device 14 to the power consumption management device 12 manually sets each device 13 in its own power demanding facility 3 in the DR target period. By operating, the power consumption in the own power demand facility 3 is reduced.

  Accordingly, the customer 4 who has transmitted the individual DR response indicating that he / she wants to participate in the DR from the dedicated terminal device 15 or the general-purpose terminal device 14 has the same amount of power consumption as the reduction specified amount I indicated by the individual DR request. Is estimated to be reduced.

  For example, the power consumption management device 12 transmits a dedicated DR request and then receives a dedicated DR response from the transmission destination of the dedicated DR request (hereinafter also referred to as response time), and the dedicated terminal device 15. The customer 4 corresponding to the transmission destination of the individual DR request is classified into one of a plurality of load groups based on the presence / absence of installation.

  FIG. 3 is a diagram for explaining a load group in the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 3, power consumption management device 12 classifies each consumer 4 into one of load group A, load group B, and load group C (automatic response group).

  The load group A is a group of consumers 4 having a long response time among the consumers 4 that do not include the dedicated terminal device 15 in the power demand facility 3.

  The load group B is a group of consumers 4 having a short response time among the consumers 4 that do not include the dedicated terminal device 15 in the power demand facility 3.

  The load group C is a group of consumers 4 including the dedicated terminal device 15 in the power demand facility 3. When receiving the individual DR request, the dedicated terminal device 15 immediately transmits an individual DR response to the power consumption management device 12, for example. For this reason, the response time is large in the order of the load groups A, B, and C.

  Note that the power consumption management device 12 is configured to classify the customers 4 that do not have the dedicated terminal device 15 in the power demand facility 3 into one of two groups, load group A and load group B, according to response time. Although there is, it is not limited to this. The power consumption management device 12 is configured to classify the customer 4 that does not include the dedicated terminal device 15 in the power demand facility 3 into one of three or more load groups set according to response time. Also good.

  Further, the power consumption management device 12 may be configured to classify each customer 4 into one of a plurality of load groups based on response time, regardless of whether or not the dedicated terminal device 15 is installed. Good.

  Hereinafter, the customer 4 belonging to the load group A is also referred to as a customer 4A, the consumer 4 belonging to the load group B is also referred to as a customer 4B, and the consumer 4 belonging to the load group C is also referred to as a customer 4C.

  As described above, the power consumption management device 12 transmits the individual DR request to the general-purpose terminal device 14 or the dedicated terminal device 15 of each consumer 4 when receiving the overall DR request from the retail business device 11. At this time, the power consumption management device 12 transmits individual DR requests at different timings for each group to which the customer 4 belongs.

  For example, the power consumption management device 12 transmits individual DR requests to the load groups in order of increasing response time. Specifically, the power consumption management device 12 transmits an individual DR request to the general-purpose terminal device 14 of each consumer 4A, and then transmits an individual DR request to the general-purpose terminal device 14 of each customer 4B. The individual DR request is transmitted to the dedicated terminal device 15 of each customer 4C.

  FIG. 4 is a diagram showing a sequence of power consumption management processing in the power consumption management system according to the embodiment of the present invention.

  Each device in the power consumption management system 101 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step of the following sequence from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  With reference to FIG. 4, first, the retail business apparatus 11 operated by the retailer 1 transmits an overall DR request to the power consumption management apparatus 12 operated by the aggregator 2 (step S11). The overall DR request indicates the DR target period and the reduction designated total amount G as described above.

  Next, when receiving the overall DR request from the retail business apparatus 11, the power consumption management device 12 distributes the reduction designated total amount G indicated by the overall DR request to the load group A, the load group B, and the load group C. Specifically, in order to achieve the reduction designated total amount G, a target value of the amount of power to be reduced by each of the load group A, the load group B, and the load group C is set (step S12). Hereinafter, the target value of the electric energy is also referred to as a group target amount T.

  For example, when the reduction designated total amount G is 1000 kW, the power consumption management apparatus 12 sets the group target amount T of the load group A to 500 kWh, which is 50% of the reduction designated total amount G. Further, the power consumption management device 12 sets the group target amount T of the load group B to 300 kWh, which is 30% of the reduction designated total amount G. Further, the power consumption management device 12 sets the group target amount T of the load group C to 200 kWh, which is 20% of the specified reduction total amount G.

  Next, the power consumption management device 12 determines the content of the individual DR request to be transmitted to the general-purpose terminal device 14 of each consumer 4A based on the set group target amount T of the load group A. Specifically, the power consumption management device 12 determines the specified reduction amount I for each customer 4A by distributing the group target amount T of the load group A to each customer 4A (step S13).

  Next, the power consumption management device 12 transmits, for example, the individual DR request indicating the determined reduction specified amount I and the target period of the DR to the general-purpose terminal device 14 of each consumer 4A, for example (step S14). The power consumption management device 12 is not limited to the configuration that transmits the individual DR request to the general-purpose terminal devices 14 of all the consumers 4A, but may be configured to transmit the individual DR request to the general-purpose terminal devices 14 of some consumers 4A. Good.

  Next, the general-purpose terminal device 14 of the consumer 4A receives the individual DR request from the power consumption management device 12, and displays the content of the individual DR request on its own display, for example. The consumer 4A confirms the display on the display and transmits an individual DR response from the general-purpose terminal device 14 to the power consumption management device 12 (step S15).

  The transmission of the individual DR response from the general-purpose terminal device 14 to the power consumption management device 12 is performed when the consumer 4 operates the general-purpose terminal device 14. Therefore, there is variation in the timing at which the power consumption management device 12 receives the individual DR response from each general-purpose terminal device 14. For example, the power consumption management device 12 waits for a predetermined time while receiving the individual DR response from each general-purpose terminal device 14.

  The time that the power consumption management device 12 waits while receiving the individual DR response from the general-purpose terminal device 14 of each consumer 4A is, for example, a time determined based on the statistical value of the response time of each customer 4A. .

  Next, the power consumption management device 12 determines the reduction designation amount I for each customer 4B based on the group target amount T of the load group A and the individual DR response received from the general-purpose terminal device 14 up to the present time. (Step S16).

Specifically, the power consumption management device 12 sets a reduction designated total amount Ib for the load group B according to the following equation (1), and for each customer 4B based on the set reduction designated total amount Ib. The specified reduction amount I is determined. However, Ta is the group target amount of the load group A, and Tb is the group target amount of the load group B. Further, F1 is the power consumption estimated at the present time to be reduced by each consumer 4A, obtained based on the individual DR response from each consumer 4A, and F2 is the individual DR response at the present time. This is a predicted value of the amount of power consumed by the non-transmitted customer 4A.
Ib = Ta + Tb− (F1 + F2) (1)

  For example, if Ta = 500 kWh, Tb = 300 kWh, F1 = 400 kWh, and F2 = 50 kWh, then Ib = 350 kWh. The power consumption management device 12 determines the reduction designation amount I for each consumer 4B by allocating the reduction designation total amount Ib to each consumer 4B.

  Next, the power consumption management device 12 transmits, for example, the individual DR request indicating the determined reduction specified amount I and the target period of the DR to the general-purpose terminal device 14 of each consumer 4B, for example (step S17).

  Next, the general-purpose terminal device 14 of the customer 4B receives the individual DR request from the power consumption management device 12, and displays the content of the individual DR request on its own display, for example. The consumer 4B confirms the display on the display, and transmits an individual DR response from the general-purpose terminal device 14 to the power consumption management device 12 (step S18).

  As described above, the timing at which the power consumption management device 12 receives the individual DR response from each general-purpose terminal device 14 varies. While receiving the individual DR responses from the general-purpose terminal devices 14 of the customer 4A and the customer 4B, for example, it waits until a predetermined time before the DR target period.

  Next, the power consumption management device 12 is estimated based on the individual DR responses from each customer 4A and each customer 4B and estimated to be reduced by the customer 4A and the customer 4B at the present time. Based on the amount of electric power, the aggregator 2 determines whether or not to participate in the DR requested by the retailer 1. For example, the aggregator 2 determines to participate in the DR when the difference between the power consumption and the reduction designated total amount G indicated by the overall DR request is within a predetermined value.

  Next, the power consumption management device 12 transmits an overall DR response indicating whether or not to participate in the DR requested by the retailer 1 to the retailer device 11 (step S19). Here, the power consumption management device 12 transmits an overall DR response to participate in DR to the retail business device 11.

Next, for example, immediately before the start of the DR target period, the power consumption management apparatus 12 sets the reduction specified total amount Ic for the load group C based on the following equation (2). However, G is the reduction designated total amount G, and F3 may be reduced by the customer 4A and the customer 4B at the present time obtained based on the individual DR response from each customer 4A and each customer 4B. This is the estimated power consumption.
Ic = G−F3 (2)

  That is, the reduction specified total amount Ic is a difference between the reduction specified total amount G and the reduced power consumption estimated by the individual DR responses from the load groups other than the load group C.

  Next, the power consumption management device 12 determines the reduction designation amount I for each customer 4C by allocating the reduction designation total amount Ic to each consumer 4C (step S20).

  Next, the power consumption management device 12 sends, for example, the individual DR request indicating the determined reduction target amount I and the target period of the DR to the dedicated terminal device 15 of each customer 4C, for example, at the start time of the DR target period. Transmit (step S21).

  Next, when receiving the individual DR request from the power consumption management device 12, the dedicated terminal device 15 of each customer 4 </ b> C transmits, for example, an individual DR response to the power consumption management device 12 immediately (step S <b> 22).

  The dedicated terminal device 15 that has transmitted the individual DR response indicating participation in the DR to the power consumption management device 12 reduces the power consumption in the power demand facility 3 by controlling the device 13 in its own power demand facility 3.

  As described above, the customer 4 who has transmitted the individual DR response indicating that he / she participates in the DR from the general-purpose terminal device 14 to the power consumption management device 12 manually enters each period in his / her own power demand facility 3 during the DR target period. By operating the device 13, the power consumption in the power demand facility 3 is reduced.

  Next, for example, when the DR target period ends, the power consumption management device 12 transmits a report request to the general-purpose terminal device 14 of the customer 4A and the customer 4B and the dedicated terminal device 15 of the customer 4C (step S23). ). The report request is information for requesting a report on the power consumption amount of the power demand facility 3 in the DR target period.

  Next, when receiving the report request from the power consumption management device 12, the general-purpose terminal device 14 of the customer 4A and the customer 4B and the dedicated terminal device 15 of the customer 4C are installed in the own power demand facility 3, for example. Information indicating the power consumption of the power demand facility 3 is acquired from the measurement device.

  Then, the general-purpose terminal device 14 of the customer 4A and the customer 4B and the dedicated terminal device 15 of the customer 4C indicate the power consumption amount of their own power demanding facility 3 during the DR target period based on the acquired information. Report information is created, and the created report information is transmitted to the power consumption management apparatus 12 (step S24).

  Next, the power consumption management device 12 receives report information from the general-purpose terminal device 14 of the customer 4A and the customer 4B and the dedicated terminal device 15 of the customer 4C, and based on each received report information, each demand The house 4 grasps the power consumption reduced in the DR target period.

  Next, the power consumption management device 12 calculates an incentive to each customer 4, that is, a consideration for responding to a DR request, based on the grasped power consumption (step S25). Specifically, for example, the incentive to each customer 4 is calculated so that the higher incentive can be obtained for the customer 4 belonging to the load group whose transmission timing of the individual DR request by the power consumption management device 12 is late. To do.

  Next, the power consumption management device 12 reconfigures the members of the load group A and the load group B based on, for example, the latest response times of the customer 4A and the customer 4B (step S26).

  In this example, the power consumption management device 12 is configured to transmit a report request (step S23) after the end of the target period. However, the present invention is not limited to this. For example, the power consumption management device 12 may be configured to transmit a report request regularly or irregularly regardless of the start timing or end timing of the target period.

  FIG. 5 is a diagram showing a configuration of the power consumption management apparatus according to the embodiment of the present invention.

  Referring to FIG. 5, the power consumption management device 12 includes an acquisition unit 31, a processing unit 32, a notification unit 33, a setting unit 34, a request unit 35, a classification unit 36, a storage unit 37, And a calculation unit 38. The power consumption management device 12 may be configured without the consideration calculation unit 38.

  The storage unit 37 is, for example, whether or not each customer 4 has participated in the past DR, each customer 4's past response time, each customer's 4 normal power consumption, and the load to which each customer 4 belongs. Memorize groups. For example, each unit in the power consumption management device 12 performs various processes with reference to information stored in the storage unit 37.

  The classification unit 36 classifies each customer 4 into one of the load group A, the load group B, and the load group C based on, for example, the response time of the customer 4 when DR has been performed in the past.

  Specifically, the classification unit 36 classifies the consumers 4 having a long response time into the load group A among the consumers 4 that do not include the dedicated terminal device 15 in the power demand facility 3. Further, the classification unit 36 classifies the consumers 4 having a short response time into the load group B among the consumers 4 that do not include the dedicated terminal device 15 in the power demand facility 3. Further, the classification unit 36 classifies the customer 4 having the dedicated terminal device 15 in the power demand facility 3 into the load group C.

  For example, the classification unit 36 also classifies the customer 4 whose response time has not been obtained so far into the load group A, that is, the load group with the earliest notification timing of the individual DR request. Specifically, the classifying unit 36 classifies the customer 4 newly contracted with the aggregator 2 into the load group A, for example.

  The acquisition unit 31 acquires the entire DR request transmitted from the retail business apparatus 11. The processing unit 32 notifies the setting unit 34 and the request unit 35 of the content of the entire DR request acquired by the acquisition unit 31.

  Based on the notification from the processing unit 32, the setting unit 34 sets a notification timing that is a timing for notifying each load group of an individual DR request.

  Specifically, the setting unit 34 sets different notification timings for each of the plurality of load groups. More specifically, for example, the setting unit 34 sets a notification timing later than that of the load group A in the load group B having a small response time compared to the load group A having a large response time.

  That is, the setting unit 34 sets a notification timing earlier than that of the load group B to the load group A having a large response time compared to the load group B having a small response time.

  The request unit 35 sets a group target amount T for each load group based on the notification from the processing unit 32. Then, the request unit 35 determines the content of the individual DR request to be transmitted to the general-purpose terminal device 14 of each consumer 4A, specifically, the reduction designation amount I based on the set group target amount T of the load group A. To do.

  The processing unit 32 creates an individual DR request indicating the specified reduction amount I determined by the request unit 35 and outputs the created individual DR request to the notification unit 33 at the notification timing to the load group A set by the setting unit 34. To do.

  The notification unit 33 notifies the general-purpose terminal device 14 of the individual DR request according to the notification timing set by the setting unit 34. Specifically, the individual DR request received from the processing unit 32 is notified to the general-purpose terminal device 14 of the customer 4A.

  The acquisition unit 31 acquires the individual DR response transmitted from the general-purpose terminal device 14 and the dedicated terminal device 15. The processing unit 32 notifies the request unit 35 of the content of the individual DR response acquired by the acquisition unit 31.

  Based on the content of the individual DR response from the consumer 4A notified from the processing unit 32, the request unit 35 calculates an estimated value of power consumption reduced by the consumer 4A at the current time, and based on the calculated estimated value Thus, the reduction designated total amount Ib is calculated. Specifically, for example, the request unit 35 calculates the reduction designated total amount Ib according to the above formula (1). And the request | requirement part 35 determines the reduction designation | designated quantity I about each consumer 4B by allocating the reduction designation | designated total quantity Ib to each consumer 4B.

  That is, the request unit 35 determines the content of a new individual DR request to another load group based on the content estimated by the individual DR response from the load group that has notified the individual DR request. In addition, the request | requirement part 35 may be the structure which determines the reduction | decrease designation | designated amount I about each consumer 4B by allocating the group target amount T of the load group B to each consumer 4B. In this case, the request unit 35 determines the specified reduction amount I for each customer 4B without using the above formula (1).

  The processing unit 32 creates an individual DR request indicating the specified reduction amount I for each customer 4B determined by the request unit 35, and notifies the created individual DR request to the load group B set by the setting unit 34 To the notification unit 33.

  The request unit 35 uses the content of the individual DR response from the customer 4A notified from the processing unit 32 and the content of the individual DR response from the customer 4B to reduce consumption by the customer 4A and the customer 4B. An estimated value of power at the current time is calculated.

  The processing unit 32 determines whether the aggregator 2 participates in the DR requested by the retailer 1 based on the estimated value calculated by the requesting unit 35. Then, the processing unit 32 creates an overall DR response based on the determination result, and outputs the created overall DR response to the notification unit 33. Here, the processing unit 32 outputs an overall DR response to participate in DR to the notification unit 33. The notification unit 33 notifies the retail business apparatus 11 of the overall DR response received from the processing unit 32.

  The request unit 35 calculates the reduction designated total amount Ic based on the estimated value calculated by itself. Specifically, for example, the request unit 35 calculates the reduction designated total amount Ic according to the above equation (2). And the request | requirement part 35 determines the reduction designation | designated quantity I about each consumer 4C by allocating the reduction designation | designated total quantity Ic to each consumer 4C.

  In addition, the request | requirement part 35 may be the structure which determines the reduction | decrease designation | designated amount I about each consumer 4C by allocating the group target amount T of the load group C to each consumer 4C. In this case, the request unit 35 determines the specified reduction amount I for each customer 4C without using the above equation (2).

  The processing unit 32 creates an individual DR request indicating the specified reduction amount I for each customer 4C determined by the request unit 35, and notifies the created individual DR request to the load group C set by the setting unit 34 To the notification unit 33.

  The notification unit 33 notifies the dedicated terminal device 15 of each customer 4 of the individual DR request received from the processing unit 32. That is, the notification unit 33 notifies the dedicated terminal device 15 corresponding to the load group C of the individual DR request for the customer 4C created based on the specified reduction total amount Ic.

  The acquisition unit 31 acquires report information transmitted from each general-purpose terminal device 14 and each dedicated terminal device 15. The processing unit 32 notifies the consideration calculation unit 38 of the content of the report information acquired by the acquisition unit 31.

  The consideration calculation unit 38 calculates an incentive to each customer 4 based on the content of the notified report information, that is, the amount of power consumed by the customer 4 during the DR target period. At this time, the consideration calculation unit 38 calculates the incentive to the load group C higher than the incentive to the load group A and the incentive of the load group B, for example.

  In the power consumption management system 101 according to the embodiment of the present invention, the individual DR request is configured to be information indicating the target period of DR and the specified reduction amount I, but is not limited thereto. For example, the individual DR request may be other information created based on the specified reduction amount I instead of the specified reduction amount I, for example, information indicating the operation content of the device 13.

  In this case, the consumer 4 that has transmitted the individual DR response to participate in the DR from the general-purpose terminal device 14 and the dedicated terminal device 15 that has transmitted the individual DR response to that effect have their own power demands in the DR target period. The equipment in the facility 3 is operated according to the operation content.

  In the power consumption management system 101 according to the embodiment of the present invention, the power consumption management apparatus 12 transmits individual DR requests to the load groups in the order of the response time, that is, the load groups A, B, and C. However, the present invention is not limited to this. For example, the power consumption management device 12 may be configured to transmit individual DR requests to each load group in order of increasing response time.

<Modification 1>
In the power consumption management system 101 according to the embodiment of the present invention, the power consumption management device 12 classifies each customer 4 into one of a plurality of load groups based on the response time, but the present invention is limited to this. is not. For example, the power consumption management device 12 is configured to classify each customer 4 into one of a plurality of load groups based on both a track record according to a DR request, that is, a track record of participating in the DR, and a response time. There may be.

Specifically, for example, the classification unit 36 calculates the evaluation value E according to the following formula (3). However, L is a response time, P is a participation rate in DR, and a and b are weighting factors.
E = a / L + b × P (3)

  For example, the classification unit 36 classifies the customers 4 having a small evaluation value E into the load group A, and classifies the consumers 4 having a large evaluation value E into the load group B.

  Here, for example, when the weighting factor a is sufficiently smaller than the weighting factor b, the evaluation value E is dominantly determined by the participation rate P. For example, in such a case, the classification unit 36 classifies the consumers 4 with a low participation rate P into the load group A, and classifies the consumers 4 with a high participation rate P into the load group B.

  The setting unit 34 sets an earlier notification timing of an individual DR request to the load group A, which is a load group with a low participation rate P, as compared with the load group B, which is a load group with a high participation rate P. That is, the setting unit 34 sets a late notification timing for a group with a high DR participation record as compared to a load group with a low DR participation record.

<Modification 2>
In the power consumption management system 101 according to the embodiment of the present invention, the power consumption management device 12 is configured to classify each consumer 4 into one of a plurality of load groups. However, the present invention is not limited to this. Absent. For example, the power consumption management device 12 may be configured to classify each device 13 in the power consumption management system 101 into one of a plurality of load groups.

  Specifically, for example, in the power consumption management device 12, the classification unit 36 classifies the device 13 that is not connected to the dedicated terminal device 15 into either the load group A or the load group B, and The connected devices 13 are classified into the load group C. The classification unit 36 can also classify each of the plurality of devices 13 in one power demand facility 3 into different load groups. The classification unit 36 may be configured to classify the plurality of devices 13 in one power demand facility 3 into the same load group.

  For example, the power consumption management device 12 first transmits an individual DR request to the general-purpose terminal device 14 corresponding to each device 13 belonging to the load group A. The consumer 4 corresponding to the general-purpose terminal device 14 confirms the display of the general-purpose terminal device 14 and transmits an individual DR response from the general-purpose terminal device 14 to the power consumption management device 12.

  Thereafter, the power consumption management device 12 transmits an individual DR request to the general-purpose terminal device 14 corresponding to each device 13 belonging to the load group B. The consumer 4 corresponding to the general-purpose terminal device 14 confirms the display of the general-purpose terminal device 14 and transmits an individual DR response from the general-purpose terminal device 14 to the power consumption management device 12.

  Thereafter, the power consumption management device 12 transmits an individual DR request to the dedicated terminal device 15 corresponding to each device 13 belonging to the load group C. For example, when the dedicated terminal device 15 receives an individual DR request from the power consumption management device 12 to the device 13, based on the settings registered in advance by the consumer 4, the dedicated terminal device 15 immediately sends an individual DR response, for example, immediately. Send to.

  For example, the classification unit 36 classifies the devices 13 for which the response time has not been obtained in the past DR into the load group with the earliest notification timing of the individual DR request, that is, the load group A. Specifically, the classification unit 36 also classifies the device 13 just installed, for example, into the load group A.

  By the way, there is a need for a technology that more reliably satisfies the demand for power consumption in an environment where there is a variation in the time from when a DR request is made to a plurality of power consumers until a response indicating whether or not to respond to the request is made. It is done.

  On the other hand, in the power consumption management apparatus according to the embodiment of the present invention, the setting unit 34 notifies the corresponding general-purpose terminal device 14 or the dedicated terminal device 15 of a request regarding power consumption and responds to the request. For a plurality of load groups classified based on the response time until obtaining a response regarding whether or not, a different notification timing is set for each load group as the notification timing of the request. The notification unit 33 notifies the general-purpose terminal device 14 or the dedicated terminal device 15 of the request according to the notification timing set by the setting unit 34.

  With this configuration, when making a request for power consumption, it is possible to appropriately determine for each load group at what timing before the target period the request should be made, and to make the request at the determined timing. it can.

  Therefore, in the power consumption management apparatus according to the embodiment of the present invention, there is a variation in time from when a request regarding power consumption is made to a plurality of request destinations until a response indicating whether or not to respond to the request is received. Therefore, it is possible to satisfy the demand for power consumption more reliably.

  In the power consumption management apparatus according to the embodiment of the present invention, the request unit 35 determines the content of a new request to another load group based on the content estimated from the response from the load group.

  With such a configuration, it is possible to determine the content of the request to the load group to be requested next based on the content of the response from the load group that has previously requested. Can be satisfied more reliably.

  In the power consumption management device according to the embodiment of the present invention, the setting unit 34 sets an earlier notification timing for a load group with a large response time compared to a load group with a small response time.

  With such a configuration, it is possible to make a request to a load group having a slow response early, so that, for example, more responses can be acquired before the start of the request target period.

  In the power consumption management apparatus according to the embodiment of the present invention, the setting unit 34 sets a later notification timing for a load group with a small response time compared to a load group with a large response time.

  With such a configuration, it is possible to make a request to a load group having a slow response early, so that, for example, more responses can be acquired before the start of the request target period.

  Further, in the power consumption management system according to the embodiment of the present invention, the load group is classified based on the response time and the results according to the request.

  With such a configuration, the load group can be classified more appropriately.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, the setting unit 34 sets an earlier notification timing for a load group with a lower track record than for a load group with a higher track record.

  With such a configuration, for example, after confirming the content of a response from a load group that is unlikely to respond to the request, it is possible to determine the content of the request to the load group that is highly likely to respond to the request. The overall demand for power consumption can be met more reliably.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, the setting unit 34 sets a later notification timing in a load group with a higher track record than in a load group with a lower track record.

  With such a configuration, for example, after confirming the content of a response from a load group that is unlikely to respond to the request, it is possible to determine the content of the request to the load group that is highly likely to respond to the request. The overall demand for power consumption can be met more reliably.

  In the power consumption management system according to the embodiment of the present invention, the load group member is the customer 4.

  With such a configuration, an appropriate notification timing can be set for each group of customers 4.

  In the power consumption management system according to the embodiment of the present invention, the plurality of load groups include a load group C that automatically responds to a request, and a load group A and a load group B that do not automatically respond to a request. Including.

  With such a configuration, for example, each customer 4 can be appropriately classified in an environment in which a customer 4 including a device that automatically responds to a request and a customer 4 that does not include the device are mixed. .

  In the power consumption management device according to the embodiment of the present invention, the setting unit 34 sets the latest notification timing to the load group C among the plurality of load groups.

  With such a configuration, for example, since it is possible to make a request to another load group having a slow response before the load group C having a fast response, more responses can be obtained before the start of the target period of the request. it can.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, the notification unit 33 requests based on the difference between the overall request regarding power consumption and the content estimated by the response from the load group other than the load group C. To the dedicated terminal device 15 corresponding to the load group C.

  With such a configuration, for example, it is difficult to expect a request to be implemented and a quick response, but a large number of other load groups can satisfy the request to some extent, and a reliable implementation of the request and a quick response can be expected, but a few loads. Group C can perform excellent power management to satisfy the shortage. Moreover, the request | requirement to the load group C can be utilized as an adjustment for satisfying the overall request.

  In the power consumption management apparatus according to the embodiment of the present invention, the consideration calculation unit 38 calculates the consideration for responding to the request. The consideration calculation unit 38 calculates the consideration of the load group C higher than that of other load groups.

  With such a configuration, for example, the customers 4 belonging to groups other than the load group C can be encouraged to introduce a device that automatically responds to a request.

  In the power consumption management apparatus according to the embodiment of the present invention, the classification unit 36 classifies the device 13 or the customer 4 into any one of a plurality of load groups. The classification unit 36 classifies the device 13 or the customer 4 for which no response time is obtained into a load group with the earliest notification timing.

  With such a configuration, for example, a response from the device 13 or the customer 4 whose response time has not been obtained in the past can be more reliably acquired until the start of the request target period.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
