英文摘要

      In view of the disadvantages of current methods for load forecasting in power system, a new algorithm named fuzzy support vector kernel regression method (F-SVKR) is proposed to deal with the problem. Comparison with some conventional methods, such as the artificial neural network, Kalman filtering algorithm, the method of minimizing absolute parameter estimation, the support vector machine and so on, have been performed. Expertmental results show their performance differences and provide some reference information for the further research in this domain.
