Abstract: Use the Radical basis function (RBF) network and Ordinary Least Square (OLS) to determine RBF func- tion centers. The initial load is forecasted by the trained RBF networks, and then, the fuzzy expert systems modify the initial load considering the possibility of load variation due to changes in temperature and the load behavior of holiday. Some of the Day types are divided into five classes in this paper. Test results show that the hybrid model can forecast load with a higher accuracy with a faster speed. Supporting a hybrid model for short-term load forecasting which inte- grates artificial neural networks (ANN) and fuzzy expert system.
