POWER CONTROL SYSTEM AND SOLAR POWER GENERATION SYSTEM

摘要

A solar power generation system includes a solar power generation module (4) a power conversion device for solar power generation (3) which converts DC power generated by the solar power generation module (4) to AC power, a storage battery unit (2) , and a charging and discharging control device (1) which takes the AC power converted by the power conversion device for solar power generation (3) from a self- supporting terminal (3a) and charges the storage battery unit (2) with the AC power. A control unit (16) detects input power which is taken from the self- supporting terminal (3a) and is input to the charging control device (1); acquires power generated by the solar power generation module; and reduces the input power input to the charging control device (1) when the difference between the acquired generated power and the detected input power is equal to or less than a prescribed value.
