Título: Neural Network Based Short-Term Electric Load Forecasting with Confidence Intervals
Autores: Moulin, Luciano S.; Silva, Alexandre P. Alves da
Resumo: Through traditional statistical models, like ARMA and Multilinear Regression, confidence intervals can be computed for the short-term electric load forecasting, assuming that the forecast errors follow a normal probability distribution. In this paper, the 1-24 steps ahead load forecasts are obtained through MultiLayer Perceptrons trained by the back-propagation algorithm. Three techniques for the computation of confidence intervals for this neural network based short-term load forecasting are presented: (i) Error Output, (ii) Resampling and (iii) Multilinear Regression adapted to neural networks. A comparison of the three techniques is performed through simulations of on-line forecasting.
