Charging station that incorporates renewable energy resource and energy storage is a promising solution to meet the growing charging demand of electric vehicles (EVs) without the need to expand the distribution network. The aggregation of multiple energy resources and EVs requires an efficient and flexible energy management strategy. This article presents a two-stage scheme to solve the power allocation and charging coordination of plugged-in EVs. Game-theory-based control is utilized to address the interaction among different components for respecting their individual preferences. The first stage determines the power allocation of photovoltaic, battery, and the grid as well as total charging power for EVs. In the second stage, charging power dispatch among individual EVs is coordinated based on the available total charging power determined in the first stage. As a result, the two energy management problems of charging station are addressed sequentially. The proposed solution is validated via simulation and experiment, and the comparisons with benchmarks show its advantages.

并网光伏电池充电站功率分配和电动汽​​车充电协调的两阶段方案


结合可再生能源和储能的充电站是一种很有前途的解决方案，可以满足电动汽车（EV）不断增长的充电需求，而无需扩大配电网络。多种能源资源和电动汽车的聚合需要高效、灵活的能源管理策略。本文提出了一种两阶段方案来解决插电式电动汽车的功率分配和充电协调问题。基于博弈论的控制用于解决不同组件之间的交互，以尊重其个人偏好。第一阶段确定光伏、电池、电网的功率分配以及电动汽车的总充电功率。在第二阶段，根据第一阶段确定的可用总充电功率协调各个电动汽车之间的充电功率调度。由此，充电站的两个能源管理问题依次得到解决。通过仿真和实验验证了所提出的解决方案，并且与基准的比较显示了其优势。
