PROBLEM TO BE SOLVED: To realize the leveling of power by restraining power change and voltage change. SOLUTION: This power storing system is equipped with a battery for storing electric power which is connected with a power system via a converter which system interconnects dispersed power sources containing wind power generation with a commercial power source system, and performs the leveling of power by supplying the power stored in the battery to a load. This inverse power flow method turns generated power of the dispersed power sources and various kinds of information containing weather information and load information into a data base, turns inverse power flow PS to the commercial power source system into a pattern on the basis of the various kinds of information, calculates charge and discharge power PB of the battery from the patterned inverse power flow PS and the generated power PG of the dispersed power sources, charges the battery with the generated power PG of the dispersed power sources in a light load time zone containing night, discharges the stored power of the battery in a heavy load time zone containing daytime, and makes power matched with a load power flow inversely to the commercial power source system. |
