摘 要：針對風電場發(fā)電功率的短期預(yù)測，闡述了組合預(yù)測的方法原理。分別建立基于相空間重構(gòu)的RBF 神經(jīng)網(wǎng)絡(luò)模型、時間序列模型、支持向量機模型三種單項預(yù)測模型，并在此基礎(chǔ)上確立加權(quán)系數(shù)，得到了兩個組合預(yù)測模型。預(yù)測結(jié)果顯示組合預(yù)測較單項預(yù)測的效果有了很大的改善，具有實際意義和應(yīng)用價值。

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
