With the analysis of factors effecting the generated power of PV arrays,a feedback neural network prediction model was proposed based on the weather forecasting information and similar-day selection method in this paper.In the presented methodology,the similar-day was picked from the historical data using the evaluation function and the weather forecasting information.In addition,the applied Elman neural network prediction model was built based on the power generation data in the similar-day and the weather data of similar-day and the predicted date.The experiments show that the forecasting model has high prediction accuracy.
