Increasing electric vehicle (EV) penetration in distribution networks necessitate EV charging coordination. This paper proposes a two-stage EV charging coordination mechanism that frees the distribution system operator (DSO) from extra burdens of EV charging coordination. The first stage ensures that the total charging demand meets facility constraints, and the second stage ensures fair charging welfare allocation while maximizing the total charging welfare via Nash-bargaining trading. A decentralized algorithm based on the alternating direction method of multipliers (ADMM) is proposed to protect individual privacy. The proposed mechanism is implemented on the blockchain to enable trustworthy EV charging coordination in case a third-party coordinator is absent. Simulation results demonstrate the effectiveness and efficiency of the proposed approach.

区块链实现的两阶段自主EV充电协调方法

电动汽车(EV)在配电网络中的普及率不断提高,因此需要进行电动汽车充电协调。本文提出了一种两阶段的EV充电协调机制,该机制使配电系统运营商(DSO)摆脱了EV充电协调的额外负担。第一阶段确保总充电需求满足设施约束,第二阶段确保公平的充电福利分配,同时通过纳什讨价还价交易最大化总的充电福利。为了保护个人隐私,提出了一种基于乘法器交替方向法的分散算法。所提议的机制在区块链上实施,以在缺少第三方协调器的情况下实现可信赖的EV充电协调。
