Abstract

It is an object to effectively output electrical energy of a storage battery to an electrical power system serving as a whole distributed power supply system by effectively utilizing the electrical energy within a charging ratio range that does not cause overcharging or overdischarging of the storage battery. In a hybrid distributed power supply system, the target supply electrical power is set based on the electrical power generation output of the electrical power generator and the charging state of the storage battery, and the target supply electrical power is restricted within a predetermined permissible supply electrical power range when the target supply electrical power deviates from the predetermined permissible supply electrical power range.
