摘 要：針對風電場發(fā)電功率的短期預測，闡述了組合預測的方法原理。分別建立基于相空間重構的RBF 神經網絡模型、時間序列模型、支持向量機模型三種單項預測模型，并在此基礎上確立加權系數(shù)，得到了兩個組合預測模型。預測結果顯示組合預測較單項預測的效果有了很大的改善，具有實際意義和應用價值。
關鍵詞： 神經網絡；時間序列；支持向量機；組合預測

Abstract: Aiming at short-term predication of wind generation power, this paper described the method and principle of combined prediction. This paper constructed three kinds of single predicting models, including radial basis function (RBF) neural network model based on phase space reconstruction, time series model and support vector machine model, and on this basis, weighing coefficients were determined to get two groups of combined prediction models. The predicting result shows that the effect of combined prediction is improved more than that of single prediction, with practical significance and applicable value.
Key words: neural network; time series; support vector machine; combined prediction
