自然灾害和网络入侵威胁着关键电网基础设施的正常运行。目前还没有一种被广泛接受的方法来量化电力系统的弹性。在这项工作中，电力系统的弹性是指即使在发生不利事件的情况下，系统仍能保持向关键负荷提供能量的能力。已经做了大量工作来量化分配系统的复原力。即使关键负荷位于配电系统中，除了分布式能源(DER)之外，输电系统在向配电网馈线提供能量方面也起着至关重要的作用。这项工作的重点是开发一个框架，以量化网络物理传输系统的弹性。量化输电网络的弹性，对于确定和设计适当的控制机制以最大限度地减少电网中不良事件的影响是重要的。建议的指标既基于系统基础设施，也基于不断变化的操作条件。对网络的关键参数进行图形分析和测量，以量化系统物理网络中的冗余和脆弱性。一种类似的方法被用来量化网络弹性。结果表明，所提出的框架能够量化传输系统的网络物理弹性。
Natural disasters and cyber intrusions threaten the normal operation of the critical electric grid infrastructure. There is still no widely accepted methodology to quantify the resilience in power systems. In this work, power system resiliency refers to the ability of the system to keep provide energy to the critical load even with adverse events. A significant amount of work has been done to quantify the resilience for distribution systems. Even though critical loads are located in distribution system, transmission system play a critical role in supplying energy to distribution feeder in addition to the Distributed Energy Resources (DERs). This work focuses on developing a framework to quantify the resiliency of cyber-physical transmission systems. Quantifying the resiliency of the transmission network, is important to determine and devise suitable control mechanisms to minimize the effects of undesirable events in the power grid. The proposed metric is based on both system infrastructure and with changing operating conditions. A graphical analysis along with measure of critical parameters of the network is performed to quantify the redundancy and vulnerabilities in the physical network of the system. A similar approach is used to quantify the cyber-resiliency. The results indicate the capability of the proposed framework to quantify cyber-physical resilience of the transmission systems.
