Research Abstract	This research analyzed yearly weather data such like weather reported data of Japan Meteorological Agency. After quantifying solar radiation prediction using approximation/classification technique from weather reported data except for solar radiation data, and then an advanced power output forecasting model for photovoltaic system was constructed. Additionally, this research developed an optimal operation technique of electric power system including photovoltaic system and battery system. Proposed techniques will contribute to reduce power output fluctuation of the photovoltaic system and also achieve an optimal operation with effective usage of the battery capacity, the validity of proposed techniques were confirmed by simulation results.
