Short-term Wind Power Output Forecasting Model for Economic Dispatch of Power System Incorporating Large-scale Wind Farm

This paper illustrates a wind power forecasting model based on back propagation artificial neural network(BP-ANN),considering the requirement of power output pre-forecasting of wind farm in economic dispatch both in time and accuarcy.Considering the relation of historical prediction error and future prediction error,an error forecasting model is developed based on artificial neural network(ANN).Simulation results show that the prediction error can follow the variation tendency of the error of pre-forecasting model,so considering the requirement of economical dispatch to output power prediction accuracy,a wind farm power prediction model is constructed to modify the short-term wind output power prediction.The further experimental results show that the prediction-modification model is effective.
