A Comparative-Analysis-Based Multi-Criteria Assessment of On/Off-Grid-Connected Renewable Energy Systems: A Case Study

Different configurations of on/off-grid-connected hybrid renewable energy systems (HRESs) are analyzed and compared in the present research study for optimal decision making Sub-Saharan Africa, facing problems electricity deficit. A multi-criteria analysis is performed this purpose using MATLAB software simulation. The obtained results show that levelized cost (LCOE) corresponding to 0% power supply deficit probability (PSDP) 0.0819 USD/kWh, 0.0925 0.3979 0.3251 0.1754 0.1641 0.5385 1.4515 respectively, Grid-PV/Wind/Battery, Grid-PV/Battery, Grid-Wind/Battery, Grid-Wind, PV/Wind/Battery, PV/Battery, Wind/Battery, stand-alone Wind systems. CO2 emissions 14,888.4 kgCO2/year, 16,916.6 13,139.7 6430.4 11,439 14,892.5 10,252.6 1621.5 aforementioned It found Grid-connected PV/Wind/Battery most cost-effective system leading a grid reduction 30.89%. Hybridization different sources (RESs) could significantly improve reduce emissions. However, improvement depend on used RES configuration. On-grid-connected HRESs more than off-grid-connected HRES. least polluting system, which allows by 93.66%. sensitivity has proven long-term investment, decrease battery cost, discount rate lead LCOE.
