Abstract
The present study proposes a techno-economic study for an off-grid combined green energy system (CGES). The system uses a photovoltaic (PV) system as a primary mover and a backup PEMFC system (Proton Exchange Membrane Fuel Cells). The suggested CGES is conditioned by a new advanced nature-inspired approach, named Fractional-order Pathfinder Optimizer (FOPA), which is used for the factors’ optimal size selection to decrease the value of Total Net Present (TNPV) based on the power supply possibility Loss (PSPL) for the system. To improve the performance of the system, FOPA is used for minimizing the power supply possibility loss (PSPL). For analyzing of the method efficiency, it is performed to a building in Nanping shi Village (Ye Village), Fujian, Sheng, China. Finally, the sensitivity assessment was implemented by levelized cost of energy (LCOE). Final results have been compared with several published approaches to specify the technique with higher efficacy. The outcomes demonstrate that utilizing the offered FOPA, the optimal numbers of FCs, Electrolyzers, PV systems, and hydrogen reservoir tanks are 25, 50, 20, and 30, respectively, that are happened with 4.86% EEP and 1.38% PSPl.
