配电系统经常因自然灾害造成的灾难性破坏而瘫痪。精心设计的加固可以显著提高灾后恢复操作的性能。这种性能通过与可操作性轨迹相关联的弹性测量来量化。配电系统加固问题可以表述为一个两阶段的随机问题，其中内部的操作问题解决灾后维修的适当调度和外部问题的明智选择的组件硬化。我们提出了一个确定性的单船员近似两种解决方案的方法，混合整数线性规划（MILP）制定和启发式方法。我们提供了各种IEEE测试馈线的计算证据，这表明启发式方法有效地提供了接近最佳的硬化解决方案。
Distribution systems are often crippled by catastrophic damage caused by a natural disaster. Well-designed hardening can significantly improve the performance of postdisaster restoration operations. Such performance is quantified by a resilience measure associated with the operability trajectory. The distribution system hardening problem can be formulated as a two-stage stochastic problem, where the inner operational problem addresses the proper scheduling of postdisaster repairs and the outer problem the judicious selection of components to harden. We propose a deterministic single crew approximation with two solution methods, a mixed integer linear programming (MILP) formulation and a heuristic approach. We provide computational evidence on various IEEE test feeders, which illustrates that the heuristic approach provides near-optimal hardening solutions efficiently.
