PROBLEM TO BE SOLVED: To provide a significant means for restraining harmonic troubles produced on power distribution system, in a distributed power source system. SOLUTION: For the distributed power source system, noting that the distributed power source is connected to the power distribution system via a power inverter and output current waveform from the power inverter can be freely controlled, detect distortion element in a connection end of the power distribution system, and reduce the harmonic troubles in the power distribution system, by controlling the output waveform of the distributed power source to take off only the detected distortion element.
