In order to improve forecast precision,a hybrid forecasting method based on Empirical Mode Decomposition(EMD) and Least Square Support Vector Machine(LS-SVM) is presented in this paper.

• 为了进行有效的预测,提高预测精度,提出将经验模式分解EMD(Empirical Mode Decomposition)和最小二乘支持向量机LS-SVM(Least Square Support Vector Machine)相结合对短期负荷进行预测。
