Innovative Peer-to-Peer Energy Trading in Local Energy Communities Featuring Electric Vehicle Charging Infrastructure

A local energy community is a network of energy consumers and producers who engage in peer-to-peer (P2P) energy trading, sharing locally generated power among members to optimize resource utilization and enhance grid resilience. In this paper, an operational framework focusing on such a community integrated with renewable energy sources, specifically integrating electric vehicles (EVs) within charging stations equipped with solar generation is proposed. The proposed framework leverages dynamic pricing mechanisms for EVs based on the stored energy cost, boosting owners' profits, and fostering the participation of charging stations in P2P markets. Our study, conducted across three scenarios, demonstrates significant reductions in energy costs and grid dependency, with savings of about 31% in Case 2 and 55% in Case 3 compared to conventional energy supply models. These results highlight the effectiveness of the integrated P2P trading system in enhancing economic and environmental sustainability within energy communities.
