ABSTRACT
The notion of hybrid renewable energy system (HRES) has been globally accepted as a means of electrifying remote or electricity-deficient regions based on their geographical locations. The techno-economic viability of photovoltaic (PV), wind turbines (WT), hydro, battery system (BS) and diesel generator (DG) HRES is proposed in this paper for an islanded power system by using HOMER. The sustainability of the HRES has been examined by using significant performance metrics such as net present cost (NPC), emissions, fuel consumption, cost of energy (COE), etc. The performance of the base system and HRES is carried out through technical, economic and environmental analysis; and the optimized solution is carefully chosen using minimum NPC and COE. The results obtained from the simulation demonstrate that scenario 2 has NPC of $77,164 and COE of $0.0925/kWh, which are 91.59% and 91.59% lower than the base system. The HRES is considered to be the most ecologically friendly configuration with fuel consumption of 453 L/yr, renewable fraction of 98%, CO2 of 1,184kg/yr, SO2 of 2.9 kg/yr and NOx of 6.56 kg/yr. The outcomes of the research show that PV/DG/WT/hydro/BS HRES is the most viable solution and preferred choice for standalone rural electrification projects when compared to the base system.
