Hybrid Energy Systems for Sustainable Residential Electrification

Strategic Insights -

A research study from Ecole Central Nantes has explored the possibility of incorporating renewable energy sources into residential developments, particularly in areas with high energy demands and environmental concerns. The study proposes a grid-connected hybrid photovoltaic system for residential electrification in Dhaka, Bangladesh, with the aim of reducing greenhouse gas emissions, lowering costs, and increasing the use of renewable energy. The proposed system was simulated using HOMER Pro, resulting in a cost-effective and sustainable solution that achieves a renewable fraction of 40% and a cost of energy of $0.0643/kWh.

Key Takeaways:

  • The proposed grid-connected hybrid photovoltaic system is a cost-effective and sustainable solution for residential electrification in Dhaka, Bangladesh.
  • The system achieves a renewable fraction of 40% and a cost of energy of $0.0643/kWh, making it an attractive option for reducing greenhouse gas emissions.
  • The system is designed to maximize renewable energy utilization, with four scenarios for photovoltaic and battery energy storage systems (BESS).
  • The analysis concludes that the grid-connected hybrid PV system is best suited for residential power needs, with lower cost of energy (COE), net present cost (NPC), and grid dependency.
  • The system provides grid support and reduces greenhouse gas emissions, making it a viable solution for sustainable residential electrification.
  • The study uses HOMER Pro for simulation and MATLAB-Simulink for technical feasibility verification.
