Techno-economic Design and Assessment of Grid-Isolated Hybrid Renewable Energy System for Agriculture Sector

The development and growth in renewable technologies, practically photovoltaic (PV) arrays and wind turbines (WT) have the key role to achieve the worldwide goal towards sustainable energy systems. Hybrid renewable energy system (HRES) can provide safe, eco-friendly and economic solutions for supplying the electrical load demand. This paper developed an autonomous HRES comprising PV, WT, diesel generator, battery, and converter technologies for electrification of an agriculture-isolated area, in Sudan as a real case study. Techno-economic optimization analysis for different hybridization scenarios is performed with a main target to find the most feasible configuration with least cost and harmful emission impact considering technical, economic and environmental perspectives with aid of HOMER Pro software. The results indicate that PV/WT/diesel/battery show the most feasible solution for supplying the investigated area. The system potentially gets the minimum net present cost (NPC) and cost of energy (COE) of 17.6 M$ and 0.283 $/kWh, respectively. In addition, the proposed optimal system achieves around 93.77% reduction in CO2 emissions as well as 94.14% saving in fuel consumption compared to the diesel-based energy system.
