Model Estimation of Photovoltaic Power Generation Using Partial Information
In this talk, we present a heuristic method for the estimation of a model of a photovoltaic plant, to be used for generation forecasting purposes by a Distribution System Operator (DSO). The problem is addressed in the peculiar scenario where measurements of meteorological variables at the plant site are not available, which is frequent in the case of a DSO dealing with a large number of independently owned and operated plants connected to the low voltage grid. This method efficiently exploits only power generation measurements and theoretical clear-sky irradiance, and is characterized by very low computational effort. The proposed procedure is currently in use at several DSO control centres in Italy.
