Short-term Load Forecasting System Based on Fuzzy Logic Theory and Neural Network

As the electric power system is always influenced by many factors,this paper applies fuzzy logic theory and artificial neural network,with advantages of each one.It designs an efficient short-term load forecasting system which takes elements like temperature and types of dates into special consideration.In particular,the influence of the special date on load is included.Through test,it is proved that it can promote the predicting accuracy of the system and can be applied in the short-term load forecasting system in the electric power system.
