A Feasibility Study of Solar-Wind-Diesel Hybrid System in Rural and Remote Areas of Bangladesh

Abstract

A feasibility study of a hybrid renewable energy system considering a combined use of solar-wind-diesel has been performed for rural and remote areas of Bangladesh using a software called HOMER (Hybrid Optimization Model for Electric Renewable). The predicted monthly average daily radiation in Bangladesh is 4.36 kWh/m2. The wind speed varies seasonally from 3 m/s to 5 m/s. The hybrid system analysis has showed that the electricity is generated in a year is 330,886 kWh in which 45% electricity comes from wind, 36% electricity comes from diesel generator and the remaining from solar energy. The optimized PV-wind-diesel system reduces the Net Present Cost (NPC) about 13% and 7% compared to PV-diesel generator-battery and wind-diesel generator-battery respectively, which has a similar effect on cost of energy (COE). The hybrid system will reduce CO2 emission by 37% in the local atmosphere compared to electricity draw from national grid.
