摘　　要：为减少电力系统因突发自然灾害事件导致配电网大面积停电损失,提出一种考虑动态交通网络的综合能源配电网灾后紧急响应策略。首先,通过调整燃气轮机出力和基于分布式电源个数的多微网划分方法的网络重构对配电网负荷进行恢复,最大化快速恢复配电网中负荷;其次,根据网络重构后配电网结构和负荷恢复情况,采用移动应急电源基于动态交通网络模型的最短路径算法进行选择移动路径,进一步恢复负荷供电;最后,采用改造后的IEEE33节点配电网系统进行仿真分析,基于多种灾害场景验证所提方法的正确性和有效性。In order to reduce the large-scale power outage losses of distribution network due to sudden natural disasters in power system,comprehensive energy distribution network emergency response strategy is proposed which considers the dynamic transportation network.Firstly,by adjusting the gas turbine output and the number based on the number of DG,the network reconstruction of microgrid division method restores the load of the distribution network to maximize the rapid recovery of the load;Secondly,according to the distribution network structure and load recovery after the network reconstruction,the mobile emergency power supply based on the dynamic traffic network model is the shortest.The path algorithm is used to select the moving path to further restore the load power supply.Finally,the modified IEEE33 node distribution network system is used to make simulation&analysis.A variety of disaster scenarios verify the correctness and effectiveness of the proposed method.
