This paper proposes a new approach based on particle swarm optimization (PSO) clustering analysis for short-term load forecasting (STLF). PSO is an intelligent evolutionary computation technique, it is a population-based stochastic search process, used to group historical load and weather data to each cluster which have highest similar characteristic data point. A forecasting model for each day in 24 points is established though selecting the data of learning samples by PSO clustering and using Elman neural network. This method gives sufficient play to the ability of processing non-linear problems by artificial neural network and intelligent evolutionary computation technique. The simulation results of daily and weekly loads forecasting for actual power system show that the proposed forecasting model can effectively improve the accuracy of short-term load forecasting.
