The extreme fast charging (XFC) technology helps to reduce refueling time, alleviate mile anxiety, extend driving range and finally promote the popularity of electric vehicles (EVs). However, it would also pose great challenges on the power grid infrastructure especially distribution networks, due to the large-scale and intermittent power demand. This paper proposes a coordinated planning method for power distribution networks and XFC EV charging stations, with the on-site batteries considered. Firstly, considering the traffic flow pattern, the operation of XFC stations is analyzed on both energy and power demand. Secondly, the coordinated planning model is developed to satisfy the time-varying XFC load, with both transportation and electricity constraints considered. In addition, the on-site batteries are introduced to flatten the XFC energy used and supplement its power supply. The case studies have verified the effectiveness of the proposed method. The influence of XFC on the distribution networks and the effects of the on-site storage are also studied.

考虑现场存储的极速充电站与配电网协调规划

极快充电（XFC）技术有助于减少加油时间，缓解里程焦虑，延长续航里程，最终促进电动汽车（EV）的普及。然而，由于大规模和间歇性的电力需求，这也将对电网基础设施特别是配电网络构成巨大挑战。本文提出了一种考虑现场电池的配电网络和 XFC EV 充电站的协调规划方法。首先，考虑交通流模式，从能源和电力需求两个方面分析XFC站的运行。其次，开发协调规划模型以满足随时间变化的 XFC 负载，同时考虑运输和电力约束。此外，现场电池被引入以扁平化使用的 XFC 能量并补充其电源。案例研究验证了所提出方法的有效性。还研究了 XFC 对配电网络的影响和现场存储的影响。
