That is, when there are a plurality of generators 2, the power control unit 13 calculates the sum G of the amount of power generated by all the generators 2 and the amount of power supplied from the power system 5. Note that when the total power supply amount is preset and stored in the storage unit 14, the control device 10 may acquire information on the total power supply amount.

- the power control unit 13 compares the total power supply amount G and the total power consumption amount L calculated as described above. Specifically, the supply-demand power difference (GL) representing the difference between the total power supply amount G and the total power consumption L is calculated, and the supply-demand power difference (GL) is equal to or less than the allowable power fluctuation amount C. Whether or not there is a difference between supply and demand power (GL) is larger than the power fluctuation allowable amount C (step S4).

- the total power supply amount G is larger than the total power consumption amount L more than the power fluctuation allowable amount C, in other words, the power amount equal to or larger than the power fluctuation allowable amount C is left. For this reason, the power control unit 13 performs control to increase the power consumption or reduce the amount of power to be supplied.
- the power control unit 13 checks whether or not there is power demand in another distribution line (see reference numeral 7 in FIG. 4) that can be connected to the distribution substation 1 (step S5). And when there is no power demand in other distribution lines 7 (No in Step S5), the power generation state is controlled so that the amount of power generated by the generator 2 is reduced (Step S6).

Specifically, a supply and demand power difference (LG) representing a difference between the total power consumption L and the total power supply amount G is calculated, and the supply and demand power difference (LG) is less than or equal to the allowable power fluctuation amount C. Whether or not there is a difference between supply and demand power (LG) is larger than the allowable power fluctuation amount C (step S14).

- the power control unit 13 performs control to adjust the power supply / demand balance.
- the total power consumption L is larger than the total power supply amount G to the power fluctuation allowable amount C, in other words, the amount of power equal to or larger than the power fluctuation allowable amount C is insufficient. For this reason, the power control unit 13 performs control to reduce power consumption.
- the power control unit 13 stops power supply to a part of the distribution lines 3 connected to the distribution substation 1, that is, stops power supply to the load 4 connected to the distribution line 3. Control is performed (step S15). At this time, the power control unit 13 may instruct the distribution line 3 according to the power stop instruction input by the operator, and automatically instruct the distribution line 3 according to a preset criterion. May be performed.
- Step S14 the process returns to the process of calculating the total power consumption L again (step S13), and a process for confirming that the difference between the total power consumption L and the total power supply amount G is less than the power fluctuation allowable amount C is performed.
- Step S14 the information on the load 4 connected to each distribution line 3 is held, and the power is stopped while calculating the total power consumption L based on the information, thereby reducing the time required for control. Is possible. Moreover, if the order of the distribution line 3 which stops electric power is predetermined, the supply stop of electric power will be performed according to this order.
- the “power fluctuation allowable amount C” described above is a parameter determined by the loss of the power system 5 and the load fluctuation capability of the generator 2. For example, when the distribution line 3 has a large loss, and the distribution substation 1 includes a large number of generators 2 that require time to adjust the power generation, the power fluctuation allowable amount C is set large. On the other hand, in the power system 5 including the power distribution line 3 with a small loss and the generator 2 that easily adjusts the output, the power fluctuation allowable amount C can be set small, and the power generation efficiency can be improved. it can. Also, the power fluctuation allowable amount C has different values separately when the total power consumption L exceeds the total power supply amount G and conversely when the total power consumption L falls below the total power supply amount G. It can also be set.

As for the configurations of the other control units 22 and 23, only the power control units 22 a and 23 a are illustrated in FIG. 7, but other configurations are also provided in the same manner as the control unit 21.
- each control part 21,22,23 belongs to the group G1, G2, G3 set beforehand, respectively. Accordingly, the distribution lines 3 to which the generator 2 and the load 4 are connected belong to the groups G1, G2, and G3. Thereby, each control part 21,22,23 is set to manage the generator 2 and the distribution line 3 (load 4) which belong to the same group to which self belongs as a control object. That is, the power control unit 13 in each control unit 21, 22, 23 generates power by the generator 2 belonging to the same group based on the total power supply amount G and the total power consumption L as described above. The supply and demand situation of the electric power and the electric power supplied from the electric power system 15 and the electric power consumed by the load 4 is controlled.
- control units 21, 22, and 23 in the present embodiment are connected to other control units (other devices) belonging to different groups.
- the power control units 13, 22a, 23a of the control units 21, 22, 23 also have a function of controlling the power supply / demand situation in cooperation with each other. An example thereof will be described with reference to the flowchart of FIG.
