AI总结:
本文提出SALEDI指数,通过对数变换解决大停电事件中客户中断时间的统计不确定性,验证其在五个电力公司的典型停电数据中的实用性。
摘要:
传统可靠性指标可以追踪常规小规模停电对配电系统客户造成的客户分钟中断影响。然而,大停电事件中的客户分钟中断极其多变,这使得难以用韧性指标量化这些极端事件的影响。我们通过系统平均大事件持续时间指数SALEDI,对数变换客户中断分钟数。我们解释了该新韧性指标的工作原理,与替代方法进行比较,量化其统计准确性,并使用五个电力公司的标准停电数据展示其实际应用。
英文摘要:
The impact of routine smaller outages on distribution system customers in terms of customer minutes interrupted can be tracked using conventional reliability indices. However, the customer minutes interrupted in large blackout events are extremely variable, and this makes it difficult to quantify the customer impact of these extreme events with resilience metrics. We solve this problem with the System Average Large Event Duration Index SALEDI that logarithmically transforms the customer minutes interrupted. We explain how this new resilience metric works, compare it with alternatives, quantify its statistical accuracy, and illustrate its practical use with standard outage data from five utilities.
