Ian Dobson, Svetlana Ekisheva

AI总结:

本文通过公用事业数据对停电和恢复过程建模,提出新颖的Poisson过程模型描述输电系统弹性事件进展,并推荐了统计变异性更低的新持续时间指标。

摘要:

我们讨论了如何利用公用事业数据对停电和恢复过程进行建模,以衡量输电系统弹性事件的持续时间。我们引入了新颖的Poisson过程模型来描述弹性事件的进展过程,并利用在北美广泛收集的停电数据验证了它们的典型性。一些常用的持续时间指标表现出不切实际的极高统计变异性,我们推荐了表现更好的新持续时间指标。此外,Poisson过程模型的参数可以在不同天气条件下从观测到的网络数据中估计出来,是很有前景的典型弹性事件新模型。

英文摘要:

We discuss ways to measure duration in a power transmission system resilience event by modeling outage and restore processes from utility data. We introduce novel Poisson process models that describe how resilience events progress and verify that they are typical using extensive outage data collected across North America. Some usual duration metrics show impractically high statistical variability, and we recommend new duration metrics that perform better. Moreover, the Poisson process models have parameters that can be estimated from observed network data under different weather conditions, and are promising new models of typical resilience events.
