Abstract This paper proposes a novel resilience assessment approach for power system. Two resilience indices are developed from the perspectives of the system and individual component levels, respectively. The former one quantifies the resilience of a power system in a system-wide manner, while the latter is intended to assess the individual component through the pre-disruption and post-disruption indices. Specifically, the pre-disruption index is used to determine the weak points of the system before the occurrence of disruptions, while the post-disruption index is for designing the optimal restoration strategies. We advocate the use of impact-increment-based state enumeration method to calculate the presented indices in an efficient way without loss of accuracy. Numerical results carried out on the IEEE RTS-79 test system and the IEEE 118-bus system validate the effectiveness of the proposed approach and indices.

基于系统和组件层次的电力系统弹性评估方法

摘要 本文提出了一种新的电力系统弹性评估方法。两个弹性指数分别从系统和单个组成部分的角度发展起来。前者以系统范围的方式量化电力系统的弹性，而后者旨在通过中断前和中断后指数评估单个组件。具体而言，中断前指标用于在中断发生前确定系统的薄弱环节，而中断后指标用于设计最佳恢复策略。我们提倡使用基于影响增量的状态枚举方法以有效的方式计算所呈现的指标，而不会损失准确性。
