Design and evaluation of an island's hybrid renewable energy system in Tunisia

this paper shows a methodology for optimal sizing of island micro grids in Djerba, Tunisia containing photovoltaic panels, a wind turbine, and a tidal turbine. The battery storage system and a diesel generator are used as compensating energy sources. The process aims to find a configuration within a set of system components that meets the required system reliability requirements. The modeling of PV/wind/tidal micro grids is considered as the first step in the optimization of the selection process. This paper aims to study the sizing and optimization of the hybrid power system to supply the load of the studied location in Djerba Island, Tunisia. The objective functions are selected by minimizing the life cycle cost (LCC) and the embodied energy (EE) for a variable probability of loss of power supply (LPSP 0%). MATLAB software is used in all simulations and programming of the micro grid system. Real weather data and a load profile are used to design and evaluate the sizing and optimization results, during the year 2020 to determine the highest component size of a micro grid system.
