Optimization and Feasibility Analysis of a Grid-Connected Hybrid Renewable Microgrid for Cost and Emission Reduction in Bangladesh

Year: 2026

Type: conference-paper

Abstract: The increasing demand for sustainable and reliable energy systems has accelerated the integration of renewable energy technologies to reduce fossil fuel dependency and grid instability. This paper presents the design and techno-economic optimization of a grid-connected PV–Wind–Battery Energy Storage System microgrid for an educational institution in Bangladesh. The proposed system is modelled and optimized using HOMER Pro to evaluate its economic, environmental and operational performance. Simulation results indicate that the optimized hybrid microgrid reduces the Net Present Cost by 65% to $45,085 and the Cost of Energy by 75% to $0.0246/kWh compared to the existing grid-only system. The proposed system achieves an 84% renewable energy fraction and decreases annual CO2emissions by 75.3%. Furthermore, sensitivity analysis with ±40% variation in key technical and economic parameters confirms the robustness and financial viability of the proposed system. The findings demonstrate that grid-connected hybrid microgrids provide a cost-effective, reliable, and sustainable solution for institutional energy management in Bangladesh.
