Application of Hybrid Model Neural Networks to Short Term Electric Load Forecasting

This paper presents a hybrid model neural network (HMNN) based short term electric load forecasting approach.This approach combines the traditional time series model with the neural network approach.Some load components are forecasted with traditional methods and others with neural network approaches.The base component,which is periodic for the 24 hour forecasting,is modeled with a neural network.The harmonic components of the intrinsic frequency are chosen as input variables of the neural network and the neural network is trained with a rapid convergent learning algorithm.Simulation results indicate that the hybrid model neural network based load forecasting approach produces more accurate load forecasts in comparison to the traditional method and can be applied to the case of no whether material.
