Abstract

In this paper, a modelling and simulation of an hybrid system composed of photovoltaic panels, a lead-acid battery bank and a diesel generator connected in parallel, is studied. A non-linear model that depends on the solar radiation and the ambient temperature is adopted to model the photovoltaic panels. The battery is characterized by the depth of discharge deduced by a non-linear model. The genset model consists in modelling its three parts: the diesel engine, the synchronous generator and the excitation system. The system characterization and simulation demonstrate that the load is supplied during the day even in case of weather disturbs.
