移动的电源（MPS）包括移动的应急发电机、车载移动的储能系统和电动汽车，在电网紧急运行条件下具有很大的潜力作为电网支持资源，以供应关键负荷并通过快速灾难恢复来增强配电系统（DS）的弹性。我们在这里调查MPS调度（即，路由和调度）与DS动态网络重新配置相协调。我们提出了一个两阶段的恢复计划，以促进DS恢复后的高影响低概率（HILP）地震灾害。在第一阶段中，通过蒙特卡罗模拟引擎模拟地震灾害，以估计一套地震力场景下配电分支的不可用性。在第二阶段，混合整数非线性规划（MINLP）的优化模型制定DS恢复，cooptimizes的MPS和DS动态网络重构的路由和调度。然后将MINLP模型线性化为混合整数线性规划模型以降低计算复杂度，其中在不同的时间尺度上生成地震恢复力恢复策略。在IEEE 33节点测试系统上对该方法的有效性进行了评估，结果验证了该方法的有效性，并显着减少了负荷中断，提高了电力系统对HILP地震的恢复力。
Mobile power sources (MPSs), including mobile emergency generators, truck-mounted mobile energy storage systems, and electric vehicles, have great potentials to be employed as grid-support resources during power grid emergency operating conditions to supply the critical loads and enhance the resilience of distribution system (DS) via a swift disaster restoration. We here investigate the MPS dispatch (i.e., routing and scheduling) in coordination with DS dynamic network reconfiguration. We propose a two-stage restoration scheme to facilitate the DS restoration following the high-impact low-probability (HILP) seismic disasters. In the first stage, a seismic hazard is simulated through a Monte Carlo simulation engine to estimate the unavailability of power distribution branches under a suite of seismic force scenarios. In the second stage, a mixed-integer nonlinear programming (MINLP) optimization model is formulated for DS restoration that cooptimizes the routing and scheduling of MPSs and DS dynamic network reconfiguration. The MINLP model is then linearized to a mixed-integer linear programming model to reduce the computation complexity, where the seismic-resilience recovery strategies are generated at different timescales. The efficacy of the proposed method is evaluated on the IEEE 33-node test system and the results verify a significant reduction in the load outages and an improved power system resilience to HILP earthquakes.
