Graphical interface development of a sizing algorithm of a photovoltaic/wind/hydrogen system

This paper presents a simulation graphical interface of a sizing algorithm of a hybrid renewable energy system. This algorithm has been developed for sizing the components of a stand-alone PV/wind/hydrogen system supplying a desalination unit which feeds the Kerkennah islands (Tunisia) with fresh water. The aim of this approach is to determine, among a list of commercially available system devices, all possible configurations of the hybrid system that would guarantee a reliable energy supply. The simulation and the display of all configurations obtained by this algorithm are performed by the graphical interface. This interface sorts the obtained combinations according to their investment cost in ascending order, selects the optimal solution and presents the various curves describing the behavior of the optimal hybrid system.
