Abstract

Abstract: A techno-economic feasibility of a stand-alone hybrid power generation for a remote community in Bangladesh is carried out in this study. The proposed system integrates a combination of biogas generator, PV modules, diesel generators, wind turbines, and lead acid battery to meet the electric load requirements using Hybrid Optimization Model for Electric Renewables (HOMER) software tool. The designated system would satisfy the energy requirements of 248 kWh/day primary load with 44.41 kW peak load. The optimized hybrid system consists of a biogas generator (9 kW), PV modules (10 kW), 2 diesel generators (10 kW each), 72 batteries (390Ah each), and 15 kW inverters. This configuration gives the COE of $0.28/kWh and total Net Present Cost (NPC) of $612280 with a renewable fraction of 60%. Additionally, the system has potential benefit to reduce CO2 emission by nearly 59.6% per year as compared to a diesel-based system and by 40.5% compared to the grid electricity. Furthermore, the results also indicate that it is fairly impossible to reach grid electricity price parity even with full government support for the project capital cost. However, the proposed system is found as an economical option than supplying electricity to the remote community with solar home systems (SHSs). Highlights: A feasibility analysis of PV-based hybrid system is carried out. HOMER is used to analysed the system sizing. Analyses for Cost of Energy, NPC, payback period, and emissions. Optimized system is economically feasible compared to SHSs and diesel only systems. Proposed system has reasonable environmental benefits and attractive payback period.
