To reduce the risk of voltage violation after gas station networks (GSNs) are attacked, this paper investigates an inter-area mobile charging strategy of plug-hybrid electric vehicles (PHEVs) to decrease the charging load by taking full advantage of charging resource. Firstly, considering the location of the charging station, waiting time and charging fee, an inter-area mobile charging strategy of PHEVs is proposed, and a mobile charging model of PHEVs among regions is established to relieve the charging pressure. Secondly, the risk index is developed to analyze the risk of voltage violation in term of the results of probabilistic load flow (PLF). Finally, the proposed strategy is tested on a modified coastal active power distribution network, and simulation results show that the charging load of PHEVs is dispersed among regions and the risk of voltage over-limit can be declined.

加油站网络攻击下PHEV跨区移动充电策略电压违规风险分析

为了降低加油站网络（GSN）受到攻击后电压违规的风险，本文研究了一种插电式混合动力电动汽车（PHEV）的跨区域移动充电策略，以充分利用充电资源来降低充电负载。首先，综合考虑充电站位置、等待时间和充电费用，提出PHEV跨区域移动充电策略，建立PHEV跨区域移动充电模型，缓解充电压力。其次，根据概率潮流（PLF）的结果，开发了风险指数来分析电压违规的风险。最后，所提出的策略在改进的沿海有源配电网络上进行了测试，
