The hybrid optimization model for electric renewable (HOMER) program was used to explore a energy system (HRES) (Version 3.14.0). Two combinations of HRES have been considered the community load in Aruthra Nagar, Puducherry, India: i) Solar photovoltaic (PV)/wind/tidal/fuel-cell (with battery storage (BESS)) and ii) PV/wind/tidal/fuel-cell(without BESS). When compared other existing evolutionary approaches proposed algorithm, Aquila optimizer (AQ), yields best results. In addition,...
