| 摘 要： | 考虑到大规模风电并网电力系统经济调度中,对风电场出力的短期预测在时间尺度和精度尺度方面的要求,以传统的反传播神经网络(back propagation artificial neural network,BP-ANN)作为预测手段的基础,建立了风电场短期出力预预测模型。考虑到历史的预测误差与未来预测误差间的映射关系,利用传统的BP-ANN预测技术对未来的预测误差进行预测。通过算例仿真发现,误差预测变化趋势能跟踪预预测的误差变化,基于此并考虑到经济调度对风电场出力预测精度的要求,建立了对风电场出力短期预预测进行修正的风电场出力短期预测模型,进一步的算例仿真表明了该模型的有效性。

| Abstract: | 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-forecastin... |
