    Abstract: A server that manages a plurality of power adjustment resources electrically connectable to a power network includes a determination unit and a first permission unit. The determination unit determines, before a vehicle including a power storage starts charging of the power storage by using the power network, whether or not electric power corresponding to charging power can be supplied to the power network by having at least one of the power adjustment resources respond to the charging of the power storage. When the determination unit determines that electric power can be supplied, the first permission unit permits supply of electric power from the power network to the vehicle.

    Abstract: A power management system includes a CEMS server that outputs a DR request to a plurality of power adjustment resources such that balancing is achieved every prescribed time period. The plurality of power adjustment resources include: a power-storage-type DER that stores the supply power in an energy form of at least one of electricity, heat and gas fuel; and a consumption-type DER that consumes the supply power by at least one of air conditioning and lighting. In a case where it is expected in the middle of the prescribed time period that the actual amount of power exceeds the planned amount of power at the end of the prescribed time period, the CEMS server outputs, to the power-storage-type DER more preferentially than to the consumption-type DER, the DR request for decreasing the actual amount of power in comparison with before expectation.

    Abstract: A computer executes resource classification and resource selection. In the resource classification, each of a plurality of resources is classified as a first resource or a second resource having lower rated charging power than the first resource. In the resource selection, resources to act as reserves are selected for a reserve request from among the plurality of resources. In the resource selection for a first reserve request, the computer selects resources corresponding to the first resource with priority over resources corresponding to the second resource, and in the resource selection for a second reserve request, the computer selects resources corresponding to the second resource with priority over resources corresponding to the first resource. An adjustment period of the second reserve request is longer than an adjustment period of the first reserve request.

    Abstract: A first switching unit switches a first power grid from an isolated operation to a grid-connected operation. In switching the first power grid from the isolated operation to the grid-connected operation, the first switching unit determines a master and a slave among a plurality of power adjustment resources and allows the first power grid to be connected to the second power grid after master-slave control by means of the master and the slave such that electric power of the first power grid is in synchronization with electric power of the second power grid. The first switching unit preferentially selects as the master, a power adjustment resource close to a point of connection between the first power grid and the second power grid from among the plurality of power adjustment resources.

    Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid, and a CEMS server that manages the plurality of power adjustment resources. The plurality of power adjustment resources include a plurality of FCEVs that supply electric power to the microgrid. Each of the plurality of FCEVs executes a refresh process that removes an oxide film formed on a catalyst electrode of an FC stack by causing the FC stack to generate electric power exceeding prescribed electric power. The CEMS server adjusts execution timings of the refresh process in the plurality of FCEVs during power supply to the microgrid, so as to respond to a request to adjust power supply and demand in the microgrid.
