尽管弹性的概念在电力系统中得到了广泛的应用，但对于如何系统地对其建模或量化尚无共识。本文首先提出了不同类型的系统风险分析的分类，并将它们与电力系统弹性的概念联系起来。随后，在智利北部电力系统暴露于地震事件的背景下，描述并应用了一个复原力评估和适应框架。这种时间依赖性分析是在整个灾难影响和网络运行和恢复时间框架内用两个指标进行评估的：能源不供应和能源不可靠性指数。最后，本文比较了基本情况与三种弹性适应策略，即鲁棒、冗余和响应情况下的预期能量年损失和不同水平网络性能的恢复周期。
Even though the concept of resilience is becoming widely used in electric power systems, there is no consensus on how to systematically model or quantify it. This article begins by proposing a classification for different types of system risk analyses, associating them to the concept of power systems resilience. Thereafter, it describes and applies a resilience assessment and adaptation framework to the Northern Chilean electric power system in the context of its exposure to seismic events. This time-dependent analysis is evaluated throughout the disaster's impact and the network's operation and restoration timeframes with two indices: Energy not Supplied and Energy Index of Unreliability. Finally, the article compares a base case with three resilience adaptation strategies, namely, robust, redundant and responsive cases, in terms of their expected energy annual loss and the return period of different levels of network performance.
