Abstract Machine learning methods such as Support Vector Machine (SVM) and Neural Network (NN) as soft computing methods are widely used to solve nonlinear problems. Wavelet analysis and artificial intelligence machine learning will be combined to improve the self learning ability and prediction accuracy. Actual historical load data is decomposed into high and low frequency load sequence by using wavelet analysis. Utilizing SVM and NN machine learning methods, choosing the appropriate parameters such as network structures, penalty parameter and kernel function width by optimization program, the single branch predictions for each sequence are separately made, and each branch prediction results are reconstructed to achieve ultimate load forecasting. Application result shows that wavelet SVM has higher prediction accuracy.
