Abstract

In this paper we present an application of dynamicsreconstruction techniques to model order estimation. Both theGrassberger–Procaccia and the Takens‘ methodwere applied, yielding similar values for the correlation dimension, hence for the model order. Based on this model order, appropriately structured neural nets for short-term prediction were designed. Satisfactory experimental results were obtained in one-hour-ahead electrical load forecasting ona six-month benchmark from an electric utility in the U.S.A.
