Building Construction Research Yields New Findings on Energy Efficiency and Sustainability

Strategic Insights -

Researchers at Chung-Ang University have proposed a robust, building-integrated charging solution for electric vehicles, which combines mobile energy storage systems, station linkage data, and traffic volume data. This innovative approach aims to promote eco-friendly EV usage, flexible energy management, and carbon neutrality through a polyfunctional Vehicle-to-Grid (V2G) architecture. The study concludes that the system yields an annual benefit of USD 47,860, a Benefit-Cost Ratio (BCR) of 6.67, and a Levelized Cost of Energy (LCOE) of USD 37.78 per MWh, demonstrating its economic viability and resilience.

Key Takeaways:

  • The proposed system integrates electric vehicle charging stations, mobile energy storage systems, and station linkage data to promote eco-friendly EV usage and carbon neutrality.
  • The system utilizes two core strategies: configuring Virtual Power Plant (VPP)-based charging packages tailored to station types, and utilizing EV batteries as distributed Energy Storage System (ESS) units.
  • K-means clustering based on spatial proximity and energy demand is followed by heuristic algorithms to improve the efficiency of mobile ESS operation.
  • A three-layer framework is used to assess improvements in energy demand distribution, with demand-oriented VPPs deployed in high-demand zones to maximize ESS utilization.
  • The system enhances station stability, increases the load factor to 132.7%, and reduces emissions by 271.5 kgCO2.
  • The system yields an annual benefit of USD 47,860, a Benefit-Cost Ratio (BCR) of 6.67, and a Levelized Cost of Energy (LCOE) of USD 37.78 per MWh.
