当地震发生时，变电站是最脆弱的组成部分之一，因此在恢复力研究中评估变电站停电风险的模型变得至关重要。在这种情况下，本文提出了一种方法来模拟变电站停电使用间隔级表示。因此，变电站停电可以采取多种形式，这取决于地震发生后不可用的间隔的具体配置。此后，我们模拟系统运行在许多中断的情况下，并通过各种指标量化系统的弹性。我们的建议适用于IEEE RTS 24总线和智利传输系统。此外，我们比较了我们提出的间隔级方法与目前用于模拟电力系统弹性变电站停电的单片方法。结果表明，间隔层方法是更实用和准确的电力网络中的变电站停电建模。
Substations are among the most vulnerable components when earthquakes occur, and thus models to assess the risk of substation outages in resilience studies are becoming critical. In this context, this paper proposes an approach to model substation outages using a bay-level representation. Hence, substation outages can take many forms depending on the specific configuration of bays unavailable after an earthquake strikes. Thereafter, we simulate the system operation under many outage scenarios and quantify system resilience through various metrics. Our proposal is applied on the IEEE RTS 24-bus and Chilean transmission systems. Furthermore, we compare our proposed bay-level approach with a monolithic method currently used to model substation outages in power system resilience. The results show that the bay-level approach is more practical and accurate for modeling substation outages in power networks.
