[Configuration of the private power generation output suppression mitigation device in the first embodiment]
As shown in FIG. 1, the private power generation output suppression mitigation device 1 is connected to a general power transmission and distribution company. A general power transmission / distribution company is a company that stably supplies power by adjusting the demand for power and the supply of power in the jurisdiction. In addition, the self-power generation output suppression mitigation device 1 includes a home energy management system (HEMS) server owned by a consumer A who does not perform private power generation, a HEMS server owned by a customer B who does not perform private power generation, and a demand for performing private power generation. The HEMS server of the house C and the HEMS server of the customer D who does not perform private power generation are connected via a network. Moreover, when not distinguishing the consumer which does not perform private power generation, and the consumer which performs private power generation, it will generically call a consumer. In addition, although the case where the HEMS server and the private power generation output suppression mitigation device 1 are connected is described here, a HEMS controller having a function only of the controller may be connected.

Next, as shown in FIG. 2, for example, the HEMS server that the customer A has is connected to a load α, a load β, a load 1, a load 2, and a network. The HEMS server controls the connected load α, load β, load 1 and load 2, respectively. Hereinafter, when the load α, the load β, the load 1 and the load 2 are not distinguished, they are simply described as the load M. The customer B, the customer C, and the customer D are similarly provided with the load M (not shown). Specifically, the load M is a device that operates by consuming electric power, such as an electric lamp, a washing machine, a dishwasher, an air conditioner, a futon dryer, and a water heater. The load M is preferably a device that does not require advance preparation for operation.
Controlling the load M includes, for example, starting the load M at a specified time, stopping the load M, and operating a specific function of the load M. The HEMS server stores information about the load M such as the power consumption of each connected load M, and transmits information about the connected load M in response to a request.

  Returning to FIG. 1, the private power generation device (not shown) of the customer C is connected to the HEMS server. Moreover, the private power generation device has a power control function that is a function for controlling the maximum power of private power generation. A function to sell the generated power as surplus power as much as possible by connecting the private power generation device and the HEMS server, and a signal that suppresses the power generated by the consumer that performs private power generation (hereinafter referred to as “suppression signal”) When the power is received, the surplus power is stored without being sold, consumed using a load, and the maximum power is suppressed by reducing the power generation efficiency.

  Next, as shown in FIG. 3, the electric power TK is supplied from the general power transmission / distribution company to the customer A, the customer B, the customer C, and the customer D through the distribution line. In addition, surplus power generated by the customer C who performs private power generation is transmitted as a reverse power RC through the distribution line. Consumer A, consumer B, and consumer D consume power TK and reverse power flow RC. In this example, it is described that consumer A, consumer B, consumer C, and consumer D consume power, but the consumer is not limited to the above-mentioned, and a consumer that does not include a HEMS server is also the same. Electric power TK and reverse power RC are consumed. In addition, the consumer who consumes electric power TK and reverse power flow RC does not need to be supplied by the same distribution line. Moreover, you may supply reverse power flow RC across the transformer in a substation.

The suppression signal SUP1 is transmitted when the supply of electric power is excessive with respect to the demand for electric power in an area under the jurisdiction of the general power transmission and distribution company. The suppression signal SUP1 is a signal that suppresses the electric power generated by a consumer who performs private power generation.
The suppression signal SUP1 includes information on a suppression rate that designates what percentage of the power generation facility capacity that the customer can generate as information for suppressing the maximum power generated by the customer who performs private power generation. . For example, when a consumer performing private power generation capable of generating power of “5” (kW) receives a suppression signal SUP1 having a suppression rate of “50” (%), the demand for performing private power generation that has received the suppression signal SUP1 The maximum power generated by the house is “2.5” (kW).
More specifically, the suppression signal SUP1 indicating that the suppression rate is “80” (%), the consumer X that performs “3” (kW) private power generation, and the demand that performs “2” (kW) private power generation. When the house Y receives each signal, the maximum power generated by the consumer X that receives the suppression signal SUP1 and that generates the power is “2.4” (kW), and the consumer that performs the private power generation that receives the suppression signal SUP1. The maximum power generated by Y is “1.6” (kW).
Further, the power consumption calculation unit 101 acquires information about the load M from the storage unit 20. In addition, the power consumption calculation unit 101 uses the power consumption based on the suppression rate indicated by the suppression signal SUP1, the information about the load M acquired from the storage unit 20, and the information on the power generation facility capacity acquired from the storage unit 20.

(Minutes) and “2” are stored in association with each other as priority information. In this case, the information about the load M is that the customer A includes the load α and the load β, the load α consumes 1500 (W) of power, and can operate for 120 (minutes), and is more than the load β. It indicates that the operation can be performed with priority, and the load β consumes 500 (W) of power, can operate 180 (minutes), and indicates that the operation priority is lower than the load α.
As information about the load M, “B” as customer information, “γ” as load information, “50” (W) as power increase information, and “360” as operating time information. (Minutes) and “1” are stored in association with each other as priority information. Furthermore, “C” as customer information, “Δ” as load information, “200” (W) as power increase information, “300” (minutes) as operating time information, and priority. “3” is stored in association with each other.
The load M memorize | stored in the memory | storage part 20 is what was selected according to the prior contract of an electric power retail company etc. and a consumer, and the consumer selected the load M which may be operated temporarily.

  The storage unit 20 further has information on the power generation facility capacity. Specifically, the information on the power generation facility capacity includes information on a consumer who performs private power generation and information on a power generation facility capacity held by the consumer who performs private power generation. For example, “X” as information on a customer who performs private power generation and “3” (kW) as information on the generated power generation capacity are stored in association with each other as information on the power generation facility capacity. Further, as information on the power generation facility capacity, “Y” is stored as information on a customer who performs private power generation, and “4” (kW) is stored as information on the power generation facility capacity held. Furthermore, “Z” is stored as information on a customer who performs private power generation, and “5” (kW) is stored as information on the capacity of the power generation facility held as information on the power generation facility capacity.

  As shown in FIG. 6, the HEMS server with which a customer is equipped may memorize | store the information about the load M, and you may make it the private electric power generation output suppression mitigation apparatus 1 acquire as needed.

  Returning to FIG. 4, the increase instruction signal transmission unit 102 transmits the power consumption increase instruction signal CMD calculated by the power consumption calculation unit 101 to the consumer HEMS server including the load M. The customer's HEMS server including the load M that has received the power consumption increase instruction signal CMD operates the load M indicated by the power consumption increase instruction signal CMD at the time indicated by the power consumption increase instruction signal CMD.

  The suppression signal calculation unit 103 calculates the second suppression signal SUP2 based on the power consumption increase calculated by the power consumption calculation unit 101, the suppression rate indicated by the suppression signal SUP1, and the information on the power generation facility capacity. . The second suppression signal SUP2 is a suppression signal indicating a suppression rate with a degree of suppression smaller than the suppression rate indicated by the suppression signal SUP1. Specifically, the suppression signal calculation unit 103 performs private power generation with the power consumption increase calculated by the power consumption calculation unit 101 being “60” (kW), the suppression rate “20” (%) indicated by the suppression signal SUP1. When the total power generation capacity of the customer is “100” (kW), the second suppression signal SUP2 indicating the suppression rate of “80” (%) is calculated.

The suppression signal transmission unit 104 transmits the second suppression signal SUP2 calculated by the suppression signal calculation unit 103 to a consumer who performs private power generation.
A consumer who performs private power generation that receives the second suppression signal SUP2 suppresses the power to be generated based on the suppression rate indicated by the second suppression signal SUP2.
Specifically, the suppression signal transmission unit 104 transmits a second suppression signal SUP2 indicating “80” (%) as a suppression rate to the customer C that performs private power generation. The customer C who performs private power generation that has received the second suppression signal SUP2 has the maximum power to be generated based on the suppression rate indicated by the second suppression signal SUP2, and is “80” (%) To suppress. That is, the maximum power generated by the customer C who performs the private power generation that has received the second suppression signal SUP2 is “3.2” (kW).

[Specific example of operation of the self-generated power output suppression mitigation device]
Next, with reference to FIG.8 and FIG.9, an example of operation | movement of the private electric power generation output suppression mitigation apparatus 1 in this embodiment is demonstrated.

FIG. 9 is a diagram illustrating an example of the power consumption increase instruction signal CMD transmitted by the increase instruction signal transmission unit 102.

Consumer A who does not perform private power generation consumes “1” (kW) of power. Consumer B who does not perform private power generation consumes “1.5” (kW). The consumer D who does not perform private power generation consumes “2” (kW) of power.
The consumer C who performs private power generation consumes “1” (kW). In addition, the maximum power generated by the customer C who performs private power generation is “4” (kW). Furthermore, the suppression amount of electricity generated by the customer C who performs private power generation is “0” (kW).
The private power generation output suppression mitigation device 1 receives a suppression signal SUP1 from a general power transmission and distribution company. “50” (%) is designated as the suppression rate indicated by the suppression signal SUP1.

The power consumption calculation unit 101 acquires information about the load M from the storage unit 20. The storage unit 20 stores “A” as customer information, “α” as load information, “1500” (W) as power increase information, and “120” (minutes) as operating time information. "1" is stored in association with each other as priority information. In the storage unit 20, as information on the load M, “A” as customer information, “β” as load information, “500” (W) as power increase information, and information on available time “180” (minutes) and “2” as priority information are stored in association with each other.

In the storage unit 20, as information on the load M, “C” as customer information, “Δ” as load information, “200” (W) as power increase information, and information on available time “300” (minutes) and “3” as priority information are stored in association with each other.
In addition, “C” is stored in the storage unit 20 as information on the power generation facility capacity, and “C” is stored as information on a customer who performs private power generation, and “4” (kW) is stored as information on the power generation facility capacity held. Has been.

The power consumption calculation unit 101 calculates “2” (kW) as the suppression amount based on the suppression rate indicated by the suppression signal SUP1 and the information on the power generation facility capacity.
The power consumption calculation unit 101 selects the load α of the consumer A that has high priority and power consumption close to the suppression amount. The power consumption calculation unit 101 calculates “1.5” (kW) as the power consumption of the increasing load. Furthermore, the power consumption calculation unit 101 calculates a power consumption increase instruction signal CMD1 for causing the consumer A to operate the load α from 13:00 to 15:00.
The suppression signal calculation unit 103 calculates “1.5” (kW) of increasing power consumption of the load calculated by the power consumption calculation unit 101 and information on the power generation facility capacity included in the power generation facility capacity information “4”. The second suppression signal SUP2 is calculated based on “(kW)” and the suppression rate “50” (%) indicated by the first suppression signal SUP1. The suppression rate indicated by the second suppression signal SUP2 is a value calculated by dividing the power consumption of the increasing load by the sum of the information on the power generation facility capacity held in the information on the power generation facility capacity, It can be calculated by adding the suppression rate indicated by 1 suppression signal SUP1. That is, the suppression rate indicated by the second suppression signal SUP2 is “87.5” (%).

The suppression signal transmission unit 104 transmits the second suppression signal SUP2 to the customer C that performs private power generation.
The customer C who performs private power generation receives the second suppression signal SUP2, and changes the maximum power to be generated from “4” (kW) to “3.5” (kW).

The increase instruction signal transmission unit 102 transmits a power consumption increase instruction signal CMD1 to the consumer A.
The consumer A who does not perform private power generation receives the power consumption increase instruction signal CMD1 and operates the load α from 13:00 to 15:00. The power consumed by the consumer A who does not perform private power generation is “1” (kW) to “2.5” (kW) from 13:00 to 15:00. The power consumption of the consumer B who does not receive the power generation increase instruction signal CMD and does not perform the private power generation and the consumer D who does not perform the private power generation does not increase.
That is, since the consumer A who does not perform private power generation has created a demand of “1.5” (kW), the degree of suppression is smaller than the suppression rate “50” (%) indicated by the suppression signal SUP1. Output suppression can be mitigated by transmitting the second suppression signal SUP2 having a rate of “87.5” (%) to the customer C that performs private power generation.

  As described above, the private power generation output suppression mitigation device 1 of the present embodiment calculates an increase in power consumption based on the suppression signal SUP1. Furthermore, the private power generation output suppression mitigation device 1 calculates a power consumption increase instruction signal CMD based on the calculated increase in power consumption, and transmits it to the consumer with the load M. The private power generation output suppression mitigation device 1 calculates a second suppression signal SUP2 having a suppression rate that is less than the suppression rate indicated by the suppression signal SUP1, based on the increase in power consumption and the suppression signal SUP1. . The private power generation output suppression mitigation device 1 transmits the second suppression signal SUP2 to the consumer that performs private power generation.

FIG. 15 is a diagram illustrating an example of a signal flow after execution of a correction plan and a change in electric energy that changes in a consumer in the present embodiment.

Consumer A who does not perform private power generation consumes “1” (kW) of power. Consumer B who does not perform private power generation consumes “2” (kW) of power. The consumer D who does not perform private power generation consumes “2” (kW) of power.
The consumer C who performs private power generation consumes “1” (kW). In addition, the maximum power generated by the customer C who performs private power generation is “4” (kW). Furthermore, the suppression amount of the customer C who performs private power generation is “0” (kW).
The private power generation output suppression mitigation device 10 receives the suppression signal SUP1 from the general power transmission and distribution company. “50” (%) is designated as the suppression rate indicated by the suppression signal SUP1.
The power consumption calculation unit 1010 acquires information about the load M from the storage unit 20.
The storage unit 20 stores “A” as customer information, “α” as load information, “1000” (W) as power increase information, and “120” (minutes) as operating time information. "1" is stored in association with each other as priority information. In the storage unit 20, as information on the load M, “A” as customer information, “β” as load information, “500” (W) as power increase information, and information on available time “180” (minutes) and “2” as priority information are stored in association with each other. In the storage unit 20, as information about the load M, “B” as customer information, “γ” as load information, “500” (W) as power increase information, and information on available time “360” (minutes) and “1” as priority information are stored in association with each other. In the storage unit 20, as information on the load M, “D” as customer information, “ε” as load information, “200” (W) as power increase information, and information on available time “300” (minutes) and “3” as priority information are stored in association with each other.
In addition, “C” is stored in the storage unit 20 as information on the power generation facility capacity, and “C” is stored as information on a customer who performs private power generation, and “4” (kW) is stored as information on the power generation facility capacity held. Has been.
The power consumption calculation unit 1010 calculates “2” (kW) as the suppression amount based on the suppression rate indicated by the suppression signal SUP1 and the information on the power generation facility capacity.

As shown in FIG. 12, in the first power consumption increase plan, the load α of the customer A is operated between 13:00 and 15:00, and the load β of the customer A is changed from 12:30 to 15:30. The load γ of the customer B is operated between 10:00 and 16:00.
As illustrated in FIG. 13, the correction plan indicates that the load ε of the customer D is selected.
Further, the power consumption calculation unit 1010 operates the load α included in the customer A from 13:00 to 15:00 based on the first power consumption increase plan, and the load β is changed from 12:30 to 15:30. Power consumption increase instruction signal CMD-F1 is calculated. Further, the power consumption calculation unit 1010 calculates a power consumption increase instruction signal CMD-F2 for operating the load γ included in the customer B from 10:00 to 16:00 based on the first power consumption increase plan. .

The suppression signal calculation unit 1030 calculates “2” (kW) of the power consumption of the increasing load calculated by the power consumption calculation unit 1010 and the information “4” (the power generation facility capacity included in the power generation facility capacity information) ( kW) and the suppression rate “50” (%) indicated by the first suppression signal SUP1 is used to calculate the second suppression signal SUP2. The suppression rate indicated by the second suppression signal SUP2 is a value calculated by dividing the power consumption of the increasing load by the sum of the information on the power generation facility capacity held in the information on the power generation facility capacity, It can be calculated by adding the suppression rate indicated by 1 suppression signal SUP1. That is, the suppression rate indicated by the second suppression signal SUP2 is “100” (%).
The suppression signal transmission unit 1040 transmits the second suppression signal SUP2 to the customer C that performs private power generation. The customer C who performs private power generation receives the second suppression signal SUP2 and keeps the suppression amount at “0” (W).
In other words, the consumer A and the consumer B create a demand of “2” (kW) for the restraining amount “2” (kW), so that the customer C who performs the private power generation generates the amount of power to be generated. There is no need to suppress this.

The increase instruction signal transmission unit 1020 transmits the power consumption increase instruction signal CMD-F1 calculated by the power consumption calculation unit 1010 to the consumer A. Next, the increase instruction signal transmission unit 1020 transmits the power consumption increase instruction signal CMD-F2 calculated by the power consumption calculation unit 1010 to the customer B.
The customer A receives the power consumption increase instruction signal CMD-F1, operates the load α from 13:00 to 15:00, and operates the load β from 12:30 to 15:30. However, since the load α is not ready and cannot be operated, the power consumed by the customer A is between “1” (kW) and “1.5” (kW) between 12:30 and 15:30. ) To increase.
The customer B receives the power consumption increase instruction signal CMD-F2 and operates the load γ from 10:00 to 16:00. The power consumed by the customer B increases from “2” (kW) to “2.5” (kW) from 10:00 to 16:00.
The power consumption of the customer C who has not received the power consumption increase instruction signal CMD-F and the customer D does not increase.

The collection unit 1050 collects information on the power consumption increased by the power consumption increase instruction signal CMD-F from a consumer with a load.
The power consumption calculation unit 1010 has the power consumption increased by the power consumption increase instruction signal CMD-F collected by the collection unit 1050 smaller than “2” (kW) assumed in the first power consumption increase plan. Since it is 1 ”(kW), the load M is calculated so that the power consumption increased from the correction plan to“ 2 ”(kW) assumed in the first power consumption increase plan. The power consumption calculation unit 1010 calculates a power consumption increase instruction signal CMD-S1 that causes the consumer D to operate the load ε based on the load M calculated from the correction plan.
The increase instruction signal transmission unit 1020 transmits the power consumption increase instruction signal CMD-S1 calculated by the power consumption calculation unit 1010 to the consumer D.
As a result of receiving the power consumption increase instruction signal CMD-S1, the consumer D increases power consumption from “2” (kW) to “2.2” (kW).

The collection unit 1050 collects information on the power consumption increased by the power consumption increase instruction signal CMD-S from a consumer with a load.
The power consumption calculation unit 1010 includes information on power consumption increased by the power consumption increase instruction signal CMD-S, information on power consumption increased by the power consumption increase instruction signal CMD-F, information on power generation equipment capacity, and a suppression signal. Based on SUP1, a suppression rate to be suppressed by the third suppression signal SUP3 is calculated. Specifically, “0.2” (kW) as the power consumption increased by the power consumption increase instruction signal CMD-S and “1” (kW) as the information of the power consumption increased by the power consumption increase instruction signal CMD-F. ), And “4” (kW) as the information on the power generation facility capacity included in the information on the power generation facility capacity, and “50” (%) of the suppression rate indicated by the first suppression signal SUP1. As a suppression rate indicated by the signal SUP3, “80”% is calculated.
The suppression signal calculation unit 1030 calculates a third suppression signal SUP3 that indicates “80” (%) calculated by the power consumption calculation unit 1010 as a suppression rate.
The suppression signal transmission unit 1040 transmits the third suppression signal SUP3 to the customer C that performs private power generation.
As a result of receiving the third suppression signal SUP3, the customer C that performs private power generation has the maximum power that is generated is “3.2” (kW).
In other words, for the restraining amount “2” (kW), when the consumer creates a demand of “1.2” (kW), the power restrained by the consumer C who performs private power generation is “0.8”. "(KW) can be relaxed.

  As described above, the private power generation output suppression and mitigation device 10 according to the present embodiment increases the demand not only to the consumer that performs private power generation but also to the consumer that does not perform private power generation, and the amount of demand created there. Accordingly, output suppression can be relaxed. Furthermore, since the private power generation output suppression mitigation device 10 includes the collection unit 1050, the created demand can be collected. Moreover, it is possible for the private power generation output suppression mitigation apparatus 10 to transmit a more appropriate suppression signal by collecting the generated demand and applying feedback. In addition, although the private power generation output suppression mitigation apparatus 10 is connected to the HEMS server with which a consumer is provided as an example, it should just be an apparatus and equipment which can respond to an increase instruction signal and a suppression signal, and is not restricted to this. .
