Supply and demand utilization devices, supply and demand utilization systems, supply and demand utilization methods, and recording media.

Abstract

A supply and demand utilization device is provided that can consider the connection status between multiple microgrids and plan the supply and demand utilization of the multiple microgrids. A supply and demand utilization device, through connection lines, plans the supply and demand utilization of a higher-level system and multiple interconnected microgrids, including: a device status acquisition unit that acquires the status of circuit breakers or switches configured on the aforementioned connection lines; an utilization area determination unit that, based on the status of the aforementioned circuit breakers or switches acquired by the aforementioned device status acquisition unit, determines, for the aforementioned multiple microgrids, areas with system connections, areas without system connections but capable of independent operation, and areas without system connections and difficult to operate independently; and a supply and demand utilization planning unit that, within the areas determined by the aforementioned utilization area determination unit, plans the supply and demand utilization of each area determined to be either an area with system connections or an area without system connections but capable of independent operation.
