Abstract
The present invention provides a household electric power system, comprising an electric control device that predicts whether voltage suppression will occur at the system side according to the historical data including voltage fluctuation at the system side, date and time, outdoor air temperature, and meteorological condition, etc. when voltage suppression occurred at the system side previously, and the present data including voltage fluctuation at the system side, date and time, outdoor air temperature, and meteorological condition, etc. The electric control device stores the surplus power generated by a solar electric power generation device as energy into an energy storage device, if voltage suppression is predicted to occur at the system side; thus, the purpose of the surplus power generated by the solar electric power generation device can be switched from selling electricity to the system side, to storing as energy.
