Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and the description thereof will not be repeated. In addition, at least a part of the embodiments described below may be arbitrarily combined.

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, an electric power retailer. The retailer 1 makes a request for DR, that is, a request for suppressing power consumption, to the aggregator 2, which is a business operator that manages each consumer 4 with respect to DR. When the aggregator 2 receives a request for DR from the retail business apparatus 11, the aggregator 2 requests DR for each consumer 4 who has a contractual relationship with the aggregator 2.

The retailer 1 requests the aggregator 2 for DR by designating 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 receives the request for DR from the retailer 1 specifies the amount of power consumption to be reduced and requests each consumer 4 for DR. 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 determines the power consumption amount to be reduced, that is, the reduction designated amount I, by each of the consumers 4 by allocating the reduction designated total amount G to each consumer 4.

FIG. 2 is a diagram showing a configuration of a power consumption management system according to an 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, for example, a server operated by the retail business 1. The power consumption management device 12 is, for example, a server operated by the aggregator 2. The retail business device 11 is connected to the power consumption management device 12 via the network 8.

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

The consumer 4 includes, for example, a consumer 4 who has a dedicated terminal device 15 installed in his / her own power demand facility 3 and a customer 4 who does not have a dedicated terminal device 15 installed in his / her own power demand facility 3. Exists. The general-purpose terminal device 14 is, for example, a communication terminal device such as a smartphone or a tablet. 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 the target period of DR and the designated reduction amount I.

The consumer 4 who has installed the dedicated terminal device 15 in his / her 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 the device 13 such as an air conditioner or a lighting device in its own 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 preset by the consumer 4, the dedicated terminal device 15 immediately immediately performs power consumption management, for example, an individual DR response indicating whether or not to comply with the content of the individual DR request. It is automatically transmitted to the device 12. Hereinafter, following the request of DR is also referred to as "participating in DR".

When the dedicated terminal device 15 transmits an individual DR response to the effect that it participates in the DR, the dedicated terminal device 15 controls each device 13 based on the content of the individual DR request, so that the power consumption in the power demand facility 3, that is, the consumer 4 Reduce power consumption.

The consumer 4 who has not installed the dedicated terminal device 15 in his / her own 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 tablet. For example, when the consumer 4 confirms the content of the individual DR request displayed on the display of the general-purpose terminal device 14, it determines whether or not to comply with the content of the individual DR request, that is, whether or not to participate in the DR, and the determination result. Is input to the general-purpose terminal device 14.

Upon receiving an input operation from the consumer 4, the general-purpose terminal device 14 transmits an individual DR response indicating whether or not to participate in the DR to the power consumption management device 12. The consumer 4 who 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, for example, manually presses each device 13 in his / her own power demand facility 3 during the target period of the DR. By operating, the amount of power consumption in the own power demand facility 3 is reduced.

Therefore, the consumer 4 who has transmitted the individual DR response to participate in the DR from the dedicated terminal device 15 or the general-purpose terminal device 14 consumes the same power consumption as the reduction specified amount I indicated by the individual DR request, and uses his / her own power demand facility 3. It is estimated that it will be reduced in.

The power consumption management device 12 has, for example, the time from transmitting the individual DR request to receiving the individual DR response from the destination of the individual DR request (hereinafter, also referred to as response time), and the dedicated terminal device 15. The consumer 4 corresponding to the destination of the individual DR request is classified into one of a plurality of load groups based on the presence or absence of the 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.

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

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

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

The load group C is a group of consumers 4 provided with a dedicated terminal device 15 in the power demand facility 3. Upon receiving the individual DR request, the dedicated terminal device 15 immediately transmits, for example, an individual DR response to the power consumption management device 12. Therefore, the response time increases in the order of load groups A, B, and C.

The power consumption management device 12 has a configuration in which the consumer 4 who does not have the dedicated terminal device 15 in the power demand facility 3 is classified into one of two groups, load group A and load group B, according to the response time. Yes, but it is not limited to this. The power consumption management device 12 has a configuration in which the consumer 4 who does not have the dedicated terminal device 15 in the power demand facility 3 is classified into one of three or more load groups set according to the response time. May be good.

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

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

As described above, when the power consumption management device 12 receives the overall DR request from the retail business device 11, 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. At this time, the power consumption management device 12 transmits an individual DR request at different timings for each group to which the consumer 4 belongs.

For example, the power consumption management device 12 transmits individual DR requests to each load group in descending order of 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, then transmits an individual DR request to the general-purpose terminal device 14 of each consumer 4B, and finally. , An individual DR request is transmitted to the dedicated terminal device 15 of each consumer 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 a program including a part or all of each step of the following sequence from a memory (not shown) and executes the program. The programs of these plurality of devices can be installed from the outside. The programs of these plurality of devices are distributed in a state of being stored in a recording medium.

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

Next, when the power consumption management device 12 receives the total DR request from the retail business device 11, the power consumption management device 12 distributes the reduction designated total amount G indicated by the total 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, each of the load group A, the load group B, and the load group C sets a target value of the electric energy to be reduced (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 device 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 reduction designated 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 group target amount T of the set load group A. Specifically, the power consumption management device 12 determines the reduction designated amount I for each consumer 4A by distributing the group target amount T of the load group A to each consumer 4A (step S13).

Next, the power consumption management device 12 collectively transmits, for example, an individual DR request indicating the determined reduction designated amount I and the target period of the DR to the general-purpose terminal device 14 of each consumer 4A (step S14). The power consumption management device 12 is not limited to a configuration in which individual DR requests are transmitted to the general-purpose terminal devices 14 of all consumers 4A, but may be configured to transmit individual DR requests to 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, for example, the content of the individual DR request on its own display. 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 are variations in the timing at which the power consumption management device 12 receives the individual DR response from each general-purpose terminal device 14. The power consumption management device 12 waits for a predetermined time while receiving, for example, an 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 consumer 4A. ..

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

Specifically, the power consumption management device 12 sets the reduction designated total amount Ib for the load group B according to the following equation (1), and for each consumer 4B based on the set reduction designation total amount Ib. The reduction designation amount I of 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 a power consumption estimated at present to be reduced by each consumer 4A, which is obtained based on an individual DR response from each consumer 4A, and F2 is an individual DR response at present. Is a predicted value of the amount of power consumption to be reduced by the untransmitted consumer 4A.
Ib = Ta + Tb- (F1 + F2) ... (1)

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

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

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

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

Next, the power consumption management device 12 is estimated to be reduced by the consumer 4A and the consumer 4B at present, which is obtained based on the individual DR response from each consumer 4A and each consumer 4B. Based on the amount of electric power, it is determined whether or not the aggregator 2 participates in the DR requested by the retailer 1. For example, the aggregator 2 determines that the aggregator 2 participates in the DR when the difference between the power consumption amount and the reduction designated total amount G indicated by the total 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 retail company 1 to the retail business device 11 (step S19). Here, the power consumption management device 12 transmits an overall DR response to the effect of participating in the DR to the retail business device 11.

Next, the power consumption management device 12 sets, for example, just before the start of the target period of DR, the reduction designated total amount Ic for the load group C based on the following equation (2). However, G is the designated total amount of reduction G, and F3 can be reduced by the consumer 4A and the consumer 4B at present, which is obtained based on the individual DR response from each consumer 4A and each consumer 4B. Estimated power consumption.
Ic = G-F3 ... (2)

That is, the reduction designated total amount Ic is the difference between the reduction designation total amount G and the reduced power consumption estimated by the individual DR response from the load group other than the load group C.

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

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

Next, when the dedicated terminal device 15 of each consumer 4C receives the individual DR request from the power consumption management device 12, the individual DR response is immediately transmitted to the power consumption management device 12, for example (step S22).

The dedicated terminal device 15 that has transmitted the individual DR response to participate 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 consumer 4 who 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 in each of his / her own power demand facilities 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 target period of DR ends, the power consumption management device 12 transmits a report request to the general-purpose terminal device 14 of the consumer 4A and the consumer 4B and the dedicated terminal device 15 of the consumer 4C (step S23). ). The report request is information for requesting a report on the power consumption of the power demand facility 3 during the target period of DR.

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

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

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

Next, the power consumption management device 12 calculates an incentive for each consumer 4, that is, a consideration for responding to a request for DR, based on the grasped power consumption amount (step S25). Specifically, for example, the incentive for each consumer 4 is calculated so that the consumer 4 belonging to the load group whose transmission timing of the individual DR request by the power consumption management device 12 is delayed can obtain a higher incentive. 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 consumer 4A and the consumer 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, but the present invention is not limited to this. For example, the power consumption management device 12 may be configured to transmit a report request periodically or irregularly regardless of the start timing or the end timing of the target period.

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

A calculation unit 38 is provided. The power consumption management device 12 may not be provided with the consideration calculation unit 38.

The storage unit 37 may, for example, indicate whether or not each consumer 4 has participated in the past DR, the past response time of each consumer 4, the normal power consumption of each consumer 4, and the load to which each consumer 4 belongs. I remember the group etc. For example, each unit in the power consumption management device 12 performs various processes with reference to the information stored in the storage unit 37.

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

Specifically, for example, the classification unit 36 calculates the evaluation value E according to the following equation (3). However, L is the response time, P is the 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 customer 4 having a small evaluation value E into the load group A, and classifies the customer 4 having a large evaluation value E into the load group B.

Here, for example, when the weighting coefficient a is sufficiently smaller than the weighting coefficient b, the evaluation value E is predominantly determined by the participation rate P. In such a case, the classification unit 36 classifies the customer 4 having a low participation rate P into the load group A and the customer 4 having a high participation rate P into the load group B, for example.

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