摘　　要：信息通信技术的发展实现了配电网的可观可控,但当配电网受到严重灾害影响而导致大停电时,配电终端设备的有效性亦会对供电恢复产生影响。为此,提出一种考虑物理-信息-交通网耦合的配电网多时段动态供电恢复策略。首先,为保证负荷的可靠恢复,该策略深入探讨信息网与配电网的耦合关系对负荷恢复的影响;其次,为最大限度地恢复负荷,考虑移动储能系统(MESS)的功率支撑作用,动态优化MESS配置节点;接着,在MESS调度过程中计及交通道路和车流量的影响,选择Floyd算法获得最短路径,实现MESS与分布式能源的时空协同供电;最后,算例研究验证了所提策略的有效性和优越性。The frequency and intensity of natural disasters have greatly increased over the past decades,and they are expected to further increase in the coming future.As a consequence,it becomes a critical issue worldwide to deal with the disasters and their impacts.More and more scholars carry out research on"grid resilience".And improving the fault recovery capability of distribution network(DN)is an important means to improve the resilience.At the same time,with the continuous deepening of the application of modern information communication technology in the power system,the power information physical system has been formed.Many blackouts indicate that the failure or attack of the information system will affect the information system and the safe and stable operation of the physical system.In this context,a multi-period dynamic power supply restoration strategy of DN considering the coupling of physical-cyber-traffic network is proposed.The impact of information network on power supply restoration is discussed in depth,and the flexible resources such as mobile energy storage systems(MESSs)are fully used for power supply restoration.Firstly,consider the fluctuation of load power and the regulation ability of controllable load.Taking load recovery as the main recovery objective.A multi-period power supply topology reconfiguration model is established to realize dynamic optimization of DN topology.Secondly,A dynamic scheduling model of MESS is established,Give play to its multi-period power support capability in time,and play its mobile role in space to achieve spatio-temporal coordinated operation with other Distributed generations.The impact of traffic flow on travelling speed of MESS is taken into account and Floyd algorithm is used for the transmission route optimization.In addition,the coupling model of information-distribution network is established based on the informationphysical network.The influence of different coupling degrees on load recovery is deeply studied.In the recovery process,the first stage is the eme
