Stand alone renewable energy system

An efficient multi-objective model and algorithm for sizing a stand

Hybrid renewable energy system (HRES) has continuously been demonstrated effective in making use of renewable energies, e.g., solar, wind. This study proposes a novel multi-objective model and algorithm for optimizing the size of a typical stand-alone HRES that is composed of photovoltaic (PV) panels, wind turbines, battery banks and diesels.
