DISTRIBUTED POWER SUPPLY SYSTEM, PHOTOVOLTAIC GENERATING SET, FUEL CELL DEVICE, AND VOLTAGE ADJUSTMENT METHOD OF DISTRIBUTED POWER SUPPLY SYSTEM

摘要

PPROBLEM TO BE SOLVED: To suppress decrease in the power generation amount of the whole system while suppressing a rise of voltage at a linkage point between distributed power supplies and a power distribution system, in a distributed power supply system constituted of a plurality of distributed power supplies which have different inverter capacities. PSOLUTION: The distributed power supply system 10 is constituted of a first distributed power supply 1 and a second distributed power supply 2, which are different in inverter capacity. Then, when a voltage at the linkage point 105 between the distributed power supply system 10 and the power system 102 exceeds a prescribed threshold voltage, reactive power and/or power generation output are controlled and adjusted in voltage preferentially from the first distributed power supply 1 which is larger in inverter capacity.
