Abstract :
The application of the wavelet neural networks (WNNs) to short-term load forecasting is reported in this work. The wavelet neural network has much higher ability of generalization and fast convergence for learning than a multilayer feedforward neural network. The Morlet wavelet has been chosen in this study as the activation function. The 3-layer backpropagation algorithm is used to train the network by learning the nonlinear relationship between input and output of the network. The input data consists of historical load and weather information, which are collected over a period of 2-years (1994-1995) to train the network and data of one year (1996) is used to test the network. The results of the network have been compared with an artificial neural network and show an improved forecast with fast convergence
