POWER SUPPLY SYSTEM, POWER SUPPLY CONTROL PROGRAM, AND POWER SUPPLY CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To improve continuity or stability of power supply to an electric power load in a power supply system comprising a distributed power source including power storage means or power generation means during a power failure in a system power source or self-sustaining operation of the distributed power source.SOLUTION: A power supply system (2) for supplying power to a plurality of electric power loads (8) comprises: a first distribution system (4-1) connecting a first electric power load (general electric power load 8-1) selected from among the plurality of electric power loads to a system power source (6); a second distribution system (4-2) connecting a second electric power load (special electric power load 8-2) selected from among the plurality of electric power loads to the system power source; and a distributed power source (10) connected to the first distribution system and including either power storage means (power storage system 12) or power generation means (FC system 14). In power supply from the system power source, the system power source supplies power to the first distribution system and the second distribution system. During a power failure in the system power source or self-sustaining operation of the distributed power source, power supply to the second distribution system is stopped and power is supplied from the distributed power source to the first distribution system.
