The present research addresses a new optimum configuration for a Hybrid Renewable Energy System (HRES). The structure includes fuel cell (FC), wind turbine (WT), and photovoltaic (PV) and its auxiliaries including the electrolyzer and the H2 tank as the storage system. The primary mover in this study is the grid, while, the proposed HRES is used during energy deficiency from the grid side. The main target is to provide an optimum number of the HRES components to get the minimum loss of power supply probability (LOPSP) and Total Net Present Cost (TNPC). For achieving better optimal results, a Modified version of African vulture optimizer (IAVO) is proposed, validated, and used in the system. Final results are applied to a building in Ahvaz, Iran and they are put in comparison with different works of the studied works. The achievements indicated the primacy of the proposed system over the other algorithms.
