Thus introduction of an alternative energy source such as solar Photo Voltaic (PV) energy is gaining momentum. Short-term photovoltaic power generation forecasting is an important task in renewable energy power system planning and operation. Based on seasonal weather classification, the Back Propagation (BP) Artificial Neural Network (ANN) approach is utilized to forecast the next 24 h PV power outputs, using weather database which include global irradiance, temperature, wind speed and humidity data of Chennai city (South-East coast of India) using a data acquisition system. The estimated results of the proposed PV power forecasting model coincide well with measurement data for a 10 kW roof top grid connected PV system. The future DC and AC power outputs are predicted for any given day. The proposed approach achieves better prediction accuracy for hot and humid climatic region. ER -
