Complex Gaussian wavelet support vector machine (CGW-SVM) is constructed with complex Gaussian wavelet kernel function for short-term load forecasting (STLF). Based on the chaotic characteristics of short-term load time series, the series is reconstructed with phase space reconstruction theory (PSRT). Then the vector of phase space is used as the input of CGW-SVM. Considering the periodical feature of power loads, the fuzzy c-means (FCM) clustering algorithm is introduced to reduce sample data. The experiments conducted in this paper show that, with the proposed method, the accuracy of load forecasting results is improved and the forecasting process is speeded up.
