Research on Improve the Prediction of BP Neural Net Photovoltaic Power Generation

The main influence factors of the photovoltaic cell output has been analyzed and the prediction model on improved the photovoltaic power generation of BP neural net was established.Based on the analysis of influence factors, using the light intensity and environment temperature to train improving BP neural network, and the predictive results of the traditional mathematical model, the traditional BP model and the improved BP model were compared.The results show that the model has relatively accurate prediction ability.
