摘要(Abstract)：

针对极端自然灾害下配电网"规模大、时间长"的故障特点,提出了一种微能源网与配电网在地表自然灾害事故处置全过程中协同提升弹性的策略。首先,结合配电网在极端灾害下的系统功能曲线,提出了全过程弹性提升策略的流程框架。其次,在配电网抵御与适应灾害阶段,提出了微能源网处于孤岛状态下的滚动停电管理方案,考虑了用户冷热电负荷的关联性和储能装置剩余容量对下一阶段的影响;再次,在故障恢复阶段,建立了考虑微能源网支撑作用的配电网故障恢复模型,包括制定故障抢修方案的主问题和制定某一抢修方案下各时段孤岛划分、负荷控制及微源出力方案的子问题,主问题与子问题交替迭代,制定最优的故障恢复策略;最后,以改进的PG&E69节点配电网进行算例分析,验证了文中方法的有效性。

关键词(KeyWords)： 微能源网;配电网;弹性;孤岛划分
