This paper describes an application of a type of neural network, called the
wavelet network, to short-term load forecasting. Based on the wavelet tran
sform theory, the recently developed wavelet network is proposed as an alte
rnative to the feed-forward neural networks for approximating arbitrary non
linear functions and for solving classification problems. Performance resul
ts are given for the daily peak and total load forecasting using data from
a real power system. A comparison among results from the wavelet network, t
he radial-basis feedforward (RBF) neural network and back-propagation (BP)
neural network shows that the wavelet network is encouraging.
