Abstract: Our paper aims to model supply and demand curves of electricity day-aheadauction in a parsimonious way. Our main task is to build an appropriatealgorithm to present the information about electricity prices and demands withfar less parameters than the original one. We represent each curve usingmesh-free interpolation techniques based on radial basis functionapproximation. We describe results of this method for the day-ahead IPEX spotprice of Italy.
