Abstract With the increase of the capacity of photovoltaic generated systems, how to eliminate the problem caused by the randomness of power output for photovoltaic system becomes more significant. A novel neutral network power forecasting model based on weather forecast is proposed to solve the randomness of power output for photovoltaic system. According to historical power and weather data provided by experiment, all factors which influence photovoltaic generated energy are discussed and neutral network forecasting module is trained and evaluated by adopting generated power series of photovoltaic arrays, day-type and temperature. Forecasting results show the high precision and high efficiency of this forecasting model which is applied in stable operation of photovoltaic generation system.
