For example, the request acquisition unit 622 acquires a permission request for requesting permission for power transmission from the trigeneration system 250 to the power grid 12 from the controller 240 of the agricultural facility 122. The permission request may be an example of a first request.

In the present embodiment, the request processing unit 624 may generate various requests for adjusting power supply and demand in the community. For example, the request processing unit 624 acquires information indicating the power supply / demand of the trigeneration system 250 of the agricultural facility 122 and information indicating the power supply / demand of the hydrogen production facility 550 of the energy management facility 124 from the power supply / demand management unit 612. . Further, the request processing unit 624 acquires information indicating the hydrogen supply / demand of the trigeneration system 250 of the agricultural facility 122 and information indicating the hydrogen supply / demand of the hydrogen production facility 550 of the energy management facility 124 from the hydrogen supply / demand management unit 614. .

Based on the information indicating the power supply and demand and the hydrogen supply and demand, the request processing unit 624 (i) the upper limit value of the amount of power that the hydrogen production facility 550 of the energy management facility 124 can receive from the power network in a specific period. (Ii) the target value of the amount of hydrogen generated by the hydrogen production facility 550 of the energy management facility 124 in a specific period; (iii) the trigeneration system 250 of the agricultural facility 122 transmits power to the power system in a specific period.

Next, the request processing unit 624 reads from the trigeneration system 250 based on the information indicating the power supply / demand of the trigeneration system 250 of the agricultural facility 122 and the information indicating the power supply / demand of the hydrogen production facility 550 of the energy management facility 124. Whether to allow power transmission to the power grid 12 is determined.

For example, the request processing unit 624 determines to prohibit power transmission when the excess hydrogen supply in the hydrogen production facility 550 of the energy management facility 124 satisfies a predetermined first condition. The first condition may be a case where the excess amount of hydrogen exceeds a predetermined degree.

Examples of the length of the unit period include one day, one week, and one month.

When the request processing unit 624 determines to permit power transmission in response to the permission request from the agricultural facility 122, the settlement unit 632 determines the amount of power supplied to the power grid 12 by the agricultural facility 122 that transmitted the permission request. The energy management facility 124 may execute a process for replacing the amount of power used to produce hydrogen. In one embodiment, the request processing unit 624 subtracts the amount of power transmitted from the trigeneration system 250 of the agricultural facility 122 according to the permission from the amount of power received from the power network 12 of the hydrogen production facility 550 of the energy management facility 124. To do. In another embodiment, the request processing unit 624 adds the transmission amount from the trigeneration system 250 of the agricultural facility 122 according to the permission to the power grid 12 to the transmission amount from the hydrogen production facility 550 of the energy management facility 124 to the power grid.

FIG. 7 schematically shows an example of information processing in the settlement unit 632. In FIG. 7, the settlement unit 632 subtracts the amount of power sold by the agricultural facility 122 to the power network 12 from the amount of power purchased by the energy management facility 124 from the power network 12. As a result, the amount of power supplied from the agricultural facility 122 to the power grid 12 can be read as the amount of power used by the energy management facility 124 to produce hydrogen.

The usage changing unit 824 may change the usage of the vehicle based on at least one of the power supply / demand situation and the hydrogen supply / demand situation in the community. For example, the usage changing unit 824 determines the number of vehicles to be allocated to each usage based on at least one of the power supply / demand situation and the hydrogen supply / demand situation in the community. The usage changing unit 824 may change the usage of each vehicle based on the determination result.

For example, the usage changing unit 824 increases the number of vehicles allocated to the usage of being rented to the user of the rental car service in the tourist season as compared with other periods. On the other hand, in the harvest season of farm work, the number of vehicles allocated for use as a hydrogen carrying device is increased compared to other periods.

In this embodiment, the vehicle allocation request acquisition unit 832 acquires a vehicle allocation request from each facility of the energy management system 100. For example, the dispatch request acquisition unit 832 acquires a dispatch request from the agricultural facility 122. The dispatch request may be an example of a second request.

In this embodiment, the vehicle allocation unit 834 manages the use of the vehicle managed by the vehicle allocation management unit 134. For example, when the vehicle allocation request acquisition unit 832 acquires a vehicle allocation request from the agricultural facility 122, the vehicle allocation unit 834 determines a vehicle to be moved to the agricultural facility 122 among one or more vehicles managed by the vehicle allocation management unit 134. The dispatching unit 834 is in the state of (i) the state of power supply and demand and hydrogen supply and demand in the agricultural facility 122 or the trigeneration system 250 of the farming facility 122, and (ii) the state of one or more vehicles managed by the dispatching management unit 134. Based on this, the vehicle to be moved to the agricultural facility 122 is determined.

In one embodiment, when the excess hydrogen supply in the trigeneration system 250 of the agricultural facility 122 satisfies the second condition, the dispatch unit 834 sends a vehicle whose remaining hydrogen amount satisfies the third condition to the agricultural facility 122. It is determined as a vehicle to be moved. The second condition may be a condition that an excessive degree of hydrogen supply exceeds a predetermined level. The third condition may be a condition that the remaining amount of hydrogen is smaller than a predetermined value. The third condition may be a condition that the remaining amount of hydrogen is a sufficient amount to reach the agricultural facility 122 and is smaller than a predetermined value.

Thus, a vehicle that can sufficiently receive the hydrogen stored in the hydrogen storage facility 264 of the agricultural facility 122 is dispatched to the agricultural facility 122. As a result, the excess of hydrogen in the agricultural facility 122 is alleviated.

In another embodiment, when the excess hydrogen supply in the trigeneration system 250 of the agricultural facility 122 satisfies the second condition, the vehicle allocation unit 834 determines that the vehicle remaining in the battery satisfies the fourth condition as the agricultural facility 122. The vehicle to be moved to is determined. The second condition may be a condition that an excessive degree of hydrogen supply exceeds a predetermined level. The fourth condition may be a condition that the remaining battery level is smaller than a predetermined value. The fourth condition may be a condition that the remaining battery level is sufficient to reach the agricultural facility 122 and is smaller than a predetermined value.

Thereby, a vehicle that can sufficiently receive the electric power generated by the fuel cell 262 of the agricultural facility 122 is dispatched to the agricultural facility 122. As a result, the excess of hydrogen in the agricultural facility 122 is alleviated.
