TL;DR
The paper addresses maximizing social welfare in energy communities by enabling P2P trading among prosumers who generate PV power, participate in DR, and host EV parking. It formulates a mixed-integer optimization that maximizes $TPC_{c,u,t}$, aggregating eight revenue/cost components $(TPG_{c,u,t}, TPDR_{c,u,t}, TPP2P_{c,u,t}, TPSW_{c,u,t}, T PHP_{c,u,t}, SCPU_{c,u,t}, TENSIC_{c,u,t}, TPEV_{c,t,ev})$ to capture internal trades, grid interactions, DR incentives, social welfare, and EV charging/discharging. The approach leverages Monte Carlo simulations with 1000 scenarios and K-means scenario reduction to three representatives, evaluating a case study with three ECs and EV parking hosting. Results indicate elevated profitability and social welfare through integrated P2P trading, DR participation, and parking hosting, while EV parking mitigates urban charging challenges and supports sustainable energy–transport operation. The work offers a practical framework for urban energy communities to coordinate local energy markets and EV charging in a way that reduces grid losses and enhances resilience.
Abstract
In smart energy communities, prosumers who both generate and consume energy play a crucial role in shaping energy management strategies. These communities use advanced platforms that enable prosumers to actively engage in the local electricity markets by setting and adjusting their own energy prices. Through peer to peer (P2P) energy trading systems, members can directly exchange energy derived from sources such as solar photovoltaic panels, electric vehicle battery storage, and demand response (DR) programs. This direct exchange not only enhances the efficiency of the network but also fosters a dynamic energy market within the community. In this article, parking-sharing services for EVs and the mechanisms of P2P energy scheduling, which facilitates the transfer and communication of power among different energy communities (ECs) are addressed. It focuses on integrating solar power, responsive electrical loads, and electric vehicles (EVs) to optimize both economic returns and social benefits for all participants. The system is designed to ensure that all energy transactions are transparent and beneficial to the proactive consumers involved. Moreover, due to urban traffic conditions and the challenges of finding suitable locations for EV charging and parking, houses in these communities provide parking-sharing services for EVs. This integration of energy management and urban scheduling illustrates a holistic approach to addressing both energy and transportation challenges, ultimately leading to more sustainable urban environments.
