Short-term electricity demand and gas price forecasts using wavelet transforms and adaptive models
Nguyen, Hang T.; Nabney, Ian T. - In: Energy 35 (2010) 9, pp. 3674-3685
This paper presents some forecasting techniques for energy demand and price prediction, one day ahead. These techniques combine wavelet transform (WT) with fixed and adaptive machine learning/time series models (multi-layer perceptron (MLP), radial basis functions, linear regression, or GARCH)....
