| Abstract: | Loading forecasting algorithms based on Support Vector Machine(SVM) are discussed in combination with least square method of its merits on reducing unsatisfactory of conventional parameters. Furthermore, Particle Swarm Optimization(PSO) is used to refine the weighted coefficient for the Least Square SVMin order to improve the computational efficiency and precision. The comparative analysis with empirical data of a province proves the intended advantages of the proposed method. |
