Optimization of power supply for an isolated site from a hybrid renewable energy system, case study: Power supply of the island of El Aouana in Jijel, Algeria

This article aims to design a hybrid renewable energy system for the autonomous power supply of a tourist complex planned on the island of El Aouana (Jijel, Algeria). This original application, based on real climate data from northern Algeria, aims to ensure permanent energy supply in this isolated site. An innovative connection scheme and rarely approached operational flexibility are introduced by combining a conventional connection to supply grid and different renewable hybrid system topologies. An economic multi-criteria comparison carried out with HOMER, between a PV/wind hybrid system, and a system combining photovoltaic sources, wind turbines, battery storage and back-up generator, shows that the PV/wind configuration responds effectively to seasonal variations in demand, sustainably reduces annual operating costs from $74.275 to $6.463, generates $17.704 in savings and avoids 289.283 g/year of CO 2 , thus strengthening the energy and tourist sustainability of the site.
