Design and performance analysis for hybrid PV-Diesel-Battery power system for residential area in Dhaka city

This paper focuses on the designed implementation and experimental analysis of hybrid PV-diesel power system to meet the residential loads in Dhaka city. The optimal design of the system is 11kW peak in residential building. National Renewable Energy Laboratories (NREL) HOMER software was used to perform the techno-economic evaluation of Hybrid PV-Diesel-Battery power system. We used a 1kW PV module to get 4% penetration, two 4kW generators and battery. Here sensitivity evaluation is also done to see the impact of solar insolation, PV investment cost, diesel fuel price on the optimum result. This system gives lowest COE US$ 0.355/kWh and total net present cost (NPC) of US$ 164,106 with a renewable fraction of 25%. This proposed hybrid power system can reduce CO₂ emission by about 922 tons per year compared to diesel generator only.
