Abstract

In order to assess power systems for exposure to cascading contingencies, this paper proposes a risk-based stress indicator, which measures the ability of the system to handle possible `N-k' contingencies under a specific operation point. Successive application of line outage distribution factor (LODF) is adopted to compute power flows following outage of K lines. The risk-based stress indicator provides the ability to continuously monitor the power system for cascading exposure. Our methodology has been verified using the IEEE 30-bus system.
级联突发事件的基于风险的压力指标
为了评估电力系统对级联突发事件的暴露,本文提出了一个基于风险的应力指标,该指标衡量系统在特定运行点下处理可能的“N-k”突发事件的能力。采用线路停电分配因子(LODF)逐次应用计算K线停电后的潮流。基于风险的应力指标提供了连续监测电力系统级联暴露的能力。我们的方法已经使用IEEE 30总线系统进行了验证。
