论文摘要
近年来,电动汽车(EV)充电站见证了迅速的增长。但是,由于单个电动汽车所有者的隐私问题,不同站点的竞争利益以及耦合分销网络约束,对充电站的有效管理具有挑战性。为了应对这一挑战,本文提出了一个两阶段的方案。在第一阶段,通过解决优化问题来得出骨料EV功率灵活性区域。我们证明,所得区域内的任何轨迹都对应于至少一个可行的EV调度策略。通过将此灵活性区域而不是详细的电动汽车数据提交到充电站运营商,可以保留电动汽车所有者的隐私权,并可以减轻计算负担。在第二阶段,考虑到AC功率流约束,开发了具有明确物理解释的分布式协调机制。我们证明所提出的机制可以融合到集中式最佳最佳。案例研究验证了理论结果。进行全面的绩效比较以证明拟议方案的优势。
In recent years, electric vehicle (EV) charging stations have witnessed a rapid growth. However, effective management of charging stations is challenging due to individual EV owners' privacy concerns, competing interests of different stations, and the coupling distribution network constraints. To cope with this challenge, this paper proposes a two-stage scheme. In the first stage, the aggregate EV power flexibility region is derived by solving an optimization problem. We prove that any trajectory within the obtained region corresponds to at least one feasible EV dispatch strategy. By submitting this flexibility region instead of the detailed EV data to the charging station operator, EV owners' privacy can be preserved and the computational burden can be reduced. In the second stage, a distributed coordination mechanism with a clear physical interpretation is developed with consideration of AC power flow constraints. We prove that the proposed mechanism is guaranteed to converge to the centralized optimum. Case studies validate the theoretical results. Comprehensive performance comparisons are carried out to demonstrate the advantages of the proposed scheme.
