摘　　要：为提升配电系统在极端天气下的弹性,提出一种配电网灾后恢复算法。针对系统发生N-k故障的场景,建立拓扑重构与分布式电源协同调度模型,最小化灾害带来的切负荷损失。在调度模型中,通过混合整数线性方程表征故障场景下的网络保持辐射状拓扑约束、分布式电源约束与系统潮流约束。该方法综合考虑了可调度分布式能源、不可调度分布式能源,以及旁路电容器的运行特性。以IEEE 33节点系统为例,选取相对严重的灾害场景,验证了故障后恢复算法的有效性。A post-disaster restoration(PDR) strategy is proposed to enhance the resilience of power system against extreme weather. Under the N-k fault scenarios,a cooperative dispatching model of topological reconfiguration and distributed generators(DGs)is established to minimize the load-shedding cost due to disasters.The PDR strategy model characterizes the radial topological constraints,DG scheduling constraints and system power flow constraints in fault scenarios as a set of mix integer linear equations.The proposed method fully considers the operating characteristics of dispatchable DGs,nondispatchable DGs and shunt capacitors. Finally,the proposed PDR strategy is validated by an IEEE 33-bus system in serious fault scenarios.
