Techno-Economic Analysis And Optimization Of Integrated Renewable Energy Systems For Rural Communities

Abstract

The need to lower carbon emissions and meet the growing demand for sustainable energy sources are driving an increase in the adoption/deployment of hybrid renewable energy systems as a practical alternative for clean power generation. This article assesses the economic and environmental performance, along with its optimum configuration, of a hybrid solar PV/wind//battery energy system intended to supply power to a commercial platform in Maiduguri, Nigeria. Using real-measured data for power demand, solar irradiance, wind speed and biomass availability, the model was created using HOMER software. It was discovered that, as compared to using standalone energy system, the PV/wind/biomass/battery hybrid system is very efficient in terms of cost and carbon savings. A 140-kW converter, 240 kW of PV modules, and a 180 kWh Li-Ion battery park are the outcomes of the energy system's ideal design. An LCOE of 2.80 $/kWh is the outcome of the optimization; also, the suggested system will reduce carbon dioxide (CO₂) emissions by nearly 40% when compared to a biomass system alone. The results of a sensitivity test indicated that the suggested hybrid system is susceptible to changes in discount rates and capital subsidies. This study shows how integrating a hybrid PV/wind/biomass/battery system in Nigeria can be economically viable and have positive environmental effects, making it a desirable option for future sustainable development.
