Increasingly frequent severe weather events in recent years threaten the security of power systems and result in major power outages throughout the world. The development of reasonable power system restoration (PSR) solutions is therefore urgently needed to speed up the recovery of the power supply while at the same time steering clear of vulnerable and risky equipment. This paper aims to develop a case-sensitive PSR model for power transmission systems that can adjust restoration solutions according to the evaluated availability of outage equipment in specific blackout scenarios and weather conditions. A novel PSR model that integrates the startup of generating units, formulation of the restoration network, renewable energy sources, and availability assessment of devices is proposed. A reformulated model is also proposed to relieve the computational burden of complex PSR problems. The availability of outage equipment is comprehensively assessed based on historical operating records, fault diagnosis results, and weather conditions. The assessed availability results are sensitive to the characteristics of real blackout cases and will support system operators generate case-sensitive PSR solutions while mitigating the vulnerable equipment. The feasibility and effectiveness of the proposed PSR model and its reformulations are verified through case studies.

基于可用性评估的案例敏感电力系统恢复策略

近年来，日益频繁的恶劣天气事件威胁着电力系统的安全，并导致世界范围内的大面积停电。因此，迫切需要开发合理的电力系统恢复 (PSR) 解决方案，以加快供电恢复速度，同时避开易受攻击和有风险的设备。本文旨在为输电系统开发一种区分大小写的 PSR 模型，该模型可以根据评估的特定停电场景和天气条件下停电设备的可用性来调整恢复解决方案。提出了一种新的 PSR 模型，它集成了发电机组的启动、恢复网络的制定、可再生能源和设备的可用性评估。还提出了一种重新制定的模型来减轻复杂 PSR 问题的计算负担。根据历史运行记录、故障诊断结果和天气情况，综合评估停电设备的可用性。评估的可用性结果对实际停电情况的特征很敏感，并将支持系统运营商生成区分大小写的 PSR 解决方案，同时减轻易受攻击的设备的影响。通过案例研究验证了所提出的 PSR 模型及其重新制定的可行性和有效性。评估的可用性结果对实际停电情况的特征很敏感，并将支持系统运营商生成区分大小写的 PSR 解决方案，同时减轻易受攻击的设备的影响。通过案例研究验证了所提出的 PSR 模型及其重新制定的可行性和有效性。评估的可用性结果对实际停电情况的特征很敏感，并将支持系统运营商生成区分大小写的 PSR 解决方案，同时减轻易受攻击的设备的影响。通过案例研究验证了所提出的 PSR 模型及其重新制定的可行性和有效性。
