REACTIVE POWER RATIO CONTROLLER, REACTIVE POWER RATIO CONTROL METHOD, AND POWER GENERATION SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve the utilization ratio of an inverter included in a storage battery system.SOLUTION: A power generation system comprises: a power generation unit utilizing renewable energy; a first inverter connected to the power generation unit; a storage battery; a second inverter connected to the storage battery; and a controller, the first inverter and the second inverter being connected at a linkage point, and the controller controlling power supply to a load via the linkage point. The controller varies a ratio between reactive power output from the first inverter and reactive power output from the second inverter, on the basis of active power output from the second inverter.
