保护电力系统免受灾难性自然灾害的影响是电力系统运行和规划中的一个日益突出的问题。本文特别考虑了地震，旨在通过开发一种新的硬件加固框架来评估和提高配电网的弹性。在该框架中，网络设备的脆弱性曲线被用来表示设备的故障概率时，面对地震，并通过蒙特卡罗方法得到的配电网的故障场景。基于配电网络拓扑结构和重要负载的位置，在所提出的框架内确定各种硬件加固策略。通过一系列的恢复力和经济分析，确定了最佳的硬化策略，以提高恢复力，并提供必要的负荷在地震期间和之后。所提出的方法的有效性进行检查，通过模拟IEEE 33节点测试馈线。
Securing the power system from catastrophic natural disasters is a rising problem in power system operation and planning. This paper particularly considers earthquake and aims to evaluate and improve the resilience of power distribution networks by developing a novel hardware hardening framework. In the proposed framework, fragility curves of the network equipment are used to represent equipment failure probabilities when facing an earthquake, and failure scenarios of the distribution network are obtained via the Monte Carlo method. Based on the distribution network topology and the locations of essential loads, various hardware hardening strategies are determined within the proposed framework. Through a series of resilience and economic analyses, the optimal hardening strategy is determined to improve the resilience and supply the essential loads during and after the earthquake. The efficacy of the proposed approach is examined through simulations on an IEEE 33-bus test feeder.
