[Operation Flowchart of Power Adjustment Device 1]
7 and 8 are operation flowcharts of the power adjustment device 1. FIG. The information acquisition unit 132 acquires status information from each of the plurality of photovoltaic power generation facilities 2, associates it with the acquired date and time, and stores the acquired status information in the storage unit 12 (S11). The information acquisition unit 132 acquires status information, for example, every second.

The instruction transmission unit 133 determines whether or not the instruction acquired by the instruction acquisition unit 131 indicates that the amount of power supplied to the power system P by the plurality of photovoltaic power generation facilities 2 is increased (S12). When the command transmitting unit 133 determines that the command indicates to increase the amount of electric power supplied to the power system P (YES in S12), the command transmitting unit 133 refers to the power generation equipment DB stored in the storage unit 12. As a result, the photovoltaic power generation facility 2 with a relatively large surplus power generation capacity is preferentially selected as the photovoltaic power generation facility 2 for increasing the amount of power to be supplied to the power system P (S13). The instruction transmission unit 133 selects, for example, the photovoltaic power generation equipment 2 whose remaining power generation capacity is equal to or greater than a predetermined threshold. The instruction transmission unit 133 selects a plurality of photovoltaic power generation facilities 2 such that the total value of the power generation capacity of the selected photovoltaic power generation facilities 2 is greater than the amount of electric power to be increased.

If the number of photovoltaic power generation facilities 2 whose remaining power generation capacity is equal to or greater than the predetermined threshold value is equal to or greater than the predetermined number (YES in S14), the instruction transmission unit 133 refers to the power generation facility DB to determine whether the photovoltaic power generation facility 2 does not have a power storage facility. The power generation facility 2 is selected (S15). If the number of photovoltaic power generation facilities 2 without power storage facilities is equal to or greater than a predetermined number (YES in S16), the instruction sending unit 133 refers to the power generation facility DB to select the photovoltaic power generation facilities 2 to be FIT-targeted. (S17).

The instruction transmission unit 133 transmits supply instruction information for instructing the selected photovoltaic power generation equipment 2 to increase the power supplied to the power system P (S18). In addition, the instruction|indication transmission part 133 transmits supply instruction information to the solar power generation equipment 2 selected in S13, when the number of the solar power generation equipment 2 is less than a predetermined number in S14 and S16.

When the command transmitting unit 133 determines in S12 that the command acquired by the command acquiring unit 131 does not indicate that the power amount is increased (NO in S12), the target power amount is set to the plurality of photovoltaic power generation facilities. 2 indicates that the amount of power to be supplied to the power system P is decreased (S20). When the instruction transmitting unit 133 determines that the target amount of power does not indicate that the amount of power supplied to the power system P by the plurality of photovoltaic power generation facilities 2 is decreased (NO in S20), the instruction transmitting unit 133 changes the amount of power. It determines that it is not necessary and returns to S11. When the instruction transmission unit 133 determines that the target amount of power indicates that the amount of power supplied to the power system P by the plurality of photovoltaic power generation facilities 2 is decreased (YES in S20), the instruction transmission unit 133 proceeds to S21 of FIG. move on.

In FIG. 8, the instruction transmission unit 133 preferentially selects the photovoltaic power generation equipment 2 with a relatively small remaining power generation capacity by referring to the power generation equipment DB stored in the storage unit 12 (S21). The instruction transmission unit 133 preferentially selects, for example, the photovoltaic power generation equipment 2 whose power generation capacity is equal to or greater than a predetermined threshold as the photovoltaic power generation equipment 2 for which the amount of power to be supplied to the power system P is to be decreased. The instruction transmission unit 133 selects, for example, the photovoltaic power generation equipment 2 whose remaining power generation capacity is less than a predetermined threshold. The instruction transmission unit 133 selects a plurality of photovoltaic power generation facilities 2 such that the total amount of power supplied to the power system P by the selected photovoltaic power generation facilities 2 is greater than the amount of power to be reduced. may

If the number of photovoltaic power generation facilities 2 whose remaining power generation capacity is less than the predetermined threshold is equal to or greater than the predetermined number (YES in S22), the instruction transmission unit 133 refers to the power generation facility DB to determine whether the photovoltaic power generation facility 2 has a power storage facility. The power generation facility 2 is selected (S23). If the number of photovoltaic power generation facilities 2 with power storage facilities is equal to or greater than a predetermined number (YES in S24), the instruction sending unit 133 refers to the power generation facility DB to select the photovoltaic power generation facilities 2 that are not subject to FIT. (S25). The instruction transmission unit 133 transmits supply instruction information for instructing the selected photovoltaic power generation equipment 2 to reduce the power supplied to the power system P (S26).

[Another method for identifying the status of the photovoltaic power generation equipment 2]
In the above description, the information acquisition unit 132 acquires the frequency of the power generated by the photovoltaic power generation facility 2 and the amount of solar radiation and temperature of the location where the photovoltaic power generation facility 2 is installed as status information. The acquisition unit 132 may acquire other information as the status information.

The information acquisition unit 132 predicts the solar power generation facility 2-1 based on the change in the amount of power generated by at least a part of the plurality of solar power generation facilities 2-1 within the immediately preceding predetermined period. The amount of change in the power generation amount of different photovoltaic power generation equipment 2-2 may be acquired as status information. The photovoltaic power generation facility 2-1 is installed, for example, west of the photovoltaic power generation facility 2-2. When moving toward the installed position, a change equivalent to the change in the solar radiation amount of the solar power generation equipment 2-1 corresponds to the distance between the solar power generation equipment 2-1 and the solar power generation equipment 2-2. It also occurs in the photovoltaic power generation facility 2-2 after a delay of time.

Therefore, the information acquisition unit 132 detects that the power generation amount of the photovoltaic power generation equipment 2-1 has changed, and only the time corresponding to the distance between the photovoltaic power generation equipment 2-1 and the photovoltaic power generation equipment 2-2. It is estimated that the amount of power generated by the photovoltaic power generation facility 2-2 will change by an amount corresponding to the amount of change in the amount of power generated by the photovoltaic power generation facility 2-1 after the time has elapsed. The time corresponding to the distance between the solar power generation equipment 2-1 and the solar power generation equipment 2-2 is, for example, the time corresponding to the distance between the solar power generation equipment 2-1 and the solar power generation equipment 2-2. It is the time obtained by dividing by the moving speed. The information acquisition unit 132 notifies the instruction transmission unit 133 of the estimated power generation amount in association with the date and time. The instruction transmission unit 133 can select the photovoltaic power generation equipment 2 that increases or decreases the amount of power supplied to the power system P based on the notified estimated amount of power generation.

Here, the direction in which the clouds move changes depending on the weather conditions. The information acquisition unit 132 may acquire, as status information, information indicating changes in weather within a predetermined period immediately before the location where the photovoltaic power generation equipment 2 is installed. Then, the instruction transmission unit 133 refers to the amount of change in the amount of power generation in order to estimate the amount of change in the amount of power generation of a certain photovoltaic power generation facility 2 based on the information indicating the weather change acquired by the information acquisition unit 132. Another photovoltaic power generation facility 2 may be selected. The instruction sending unit 133 notifies the photovoltaic power generation facility 2-2 whose amount of change in the power generation amount is to be estimated the amount of change in the power generation amount of another photovoltaic power generation facility 2 on the front side of the cloud movement. may be used to estimate the amount of change in the power generation amount of the photovoltaic power generation equipment 2-2.

FIG. 9 is a diagram for explaining the movement of clouds and changes in the amount of power generation. A shaded area in FIG. 9 indicates an area where clouds exist. FIG. 9(a) shows the cloud position at the first time T1, and FIG. 9(b) shows the cloud position at the second time T2 after the first time T1. . FIG. 9(c) shows cloud positions at a third time T3 after the second time T2. The instruction transmission unit 133 estimates the position of the cloud shown in FIG. 9(c), for example, based on the position of the cloud shown in FIG. 9(a) and the position of the cloud shown in FIG. 9(b).

The photovoltaic power generation facility 2-6 shown in FIG. 9 is at the position of the photovoltaic power generation facility 2-1 at time T1, and the cloud at the position of the photovoltaic power generation facility 2-4 at time T2 rises in the sky at time T3. It is installed where it is estimated to be. In this case, the instruction transmitting unit 133, for example, transmits status information indicating that the power generation amount of the solar power generation facility 2-1 has decreased to 50% of the normal amount at time T1, and the power generation amount of the solar power generation facility 2-4 at time T2. Based on the status information indicating that the amount has decreased to 50% of the normal amount, it is estimated that the power generation amount of the photovoltaic power generation facility 2-6 will decrease to 50% of the normal amount at time T3. By operating the instruction transmitting unit 133 in this manner, the instruction transmitting unit 133 can improve the accuracy of estimation of the amount of change in the amount of power generation of the photovoltaic power generation equipment 2, and therefore adjusts the amount of power supplied to the power system P. Accuracy can be improved.

[Error correction]
The storage unit 12 may store error information indicating the magnitude of the error in the status information in association with each of the plurality of photovoltaic power generation facilities 2 . The error information is information written in the storage unit 12 in advance by the administrator of the power adjusting device 1 . In this case, the instruction transmission unit 133 corrects the status information acquired by the information acquisition unit 132 from the photovoltaic power generation facility 2 based on the error information stored in the storage unit 12 in association with the photovoltaic power generation facility 2. Create supply order information based on By operating the instruction transmitting unit 133 in this manner, the adjustment accuracy of the amount of power supplied to the power system P can be further improved.

[Modification]
In the above description, the power adjusting device 1 supplies power for instructing a change in the amount of power to be supplied to the power system P by the plurality of photovoltaic power generation facilities 2 based on the command acquired from the operator server 3. Although the case of transmitting the instruction information is illustrated, the power adjustment device 1 may transmit the supply instruction information based on other information. For example, the instruction transmission unit 133 further based on the amount of change in the frequency of the power supplied to the electric power system P acquired by the information acquisition unit 132 causes the plurality of photovoltaic power generation facilities 2 to bring the frequency closer to a predetermined frequency. may determine the amount by which the amount of electric power to be supplied to the power system P is changed by at least a part of the power system P, and may transmit supply instruction information based on the determined amount. The predetermined frequency is, for example, 50.0 Hz or 60.0 Hz. By configuring the power adjusting device 1 in this way, even when the supply and demand balance in the electric power system P is lost at a timing other than the timing at which the operator server 3 transmits the command, the supply and demand balance can be quickly restored. can be done.
