Multi-objective optimization and feasibility analysis of integrated biogas-solar energy systems for rural electrification

Popis výsledku v původním jazyce

The growing demand for sustainable electricity in emerging economies necessitates hybrid systems that leverage local renewable resources while remaining economically viable. This study optimizes and evaluates photovoltaic-biogas (PV-BG) hybrid systems for Rosso, Mauritania, through a techno-economic and environmental framework. HOMER Pro was used for baseline modeling, while Grey Wolf Optimizer (GWO) and Whale Optimization Algorithm (WOA) refined both on-grid and off-grid designs. The optimal on-grid configuration-801 kW PV, 100 kW BG generator, and 408 kW converter-achieved a Levelized Cost of Energy (LCOE) of $0.041/kWh, Net Present Cost (NPC) of $1.89 M, Payback Period (PP) of 6.6 years, Internal Rate of Return (IRR) of 14%, and Return on Investment (ROI) of 11%. GWO and WOA further reduced LCOE to $0.038/kWh and $0.036/kWh and NPC to $1.81 M and $1.77 M, shortening PP to 6.4 and 6.1 years. Environmental analysis showed an annual offset of 1,220 tCO(2) and a 100% renewable fraction. The results provide a scalable framework for hybrid energy planning, supporting policy development and investment strategies toward low-carbon power systems.
