本文提出了一个框架，系统地衡量和评估电网的弹性，重点是性能感知的客户在配电水平。拟议的框架考虑了类似的可用性衡量标准作为弹性的基本指标，并定义了其他关键的与弹性相关的概念和指标，如阻力和脆性。该框架还提供了一个衡量电网上的负荷的功能依赖程度，并演示了弹性和依赖性的概念是如何内在相关的。它还讨论了将以人为本的过程视为基础设施系统的基本组成部分的影响。由于其定量性质，拟议的弹性框架能够创建工具来评估电网作为生命线的性能，并评估电力基础设施优化部署和运营计划的影响。讨论的支持，从最近的显着的自然灾害后进行的实地损害评估的实际例子和经验记录。
This paper presents a framework to systematically measure and assess power grids' resilience with a focus on performance as perceived by customers at the power distribution level. The proposed framework considers an analogous measure of availability as a basic metric for resilience and defines other key resilience-related concepts and metrics, such as resistance and brittleness. This framework also provides a measurement for the degree of functional dependency of loads on power grids and demonstrates how the concepts of resilience and dependency are inherently related. It also discusses the implications of considering human-centered processes as fundamental constituting components of infrastructure systems. Thanks to its quantitative nature, the proposed resilience framework enables the creation of tools to evaluate power grids' performance as a lifeline and to assess the effects of plans for optimal electrical power infrastructure deployment and operation. The discussion is supported by practical examples and empirical records from field damage assessments conducted after recent notable natural disasters.
