Distribution Resiliency Metrics – An Update on Resiliency Metrics Development and an Overview of Resiliency Industry Research

The IEEE Distribution Resiliency Working Group (DRes) is currently exploring the development of distribution system resiliency metrics. The electric utility industry currently utilizes widely accepted IEEE 1366 Reliability metrics to quantitatively measure system performance when not experiencing High Impact, Low Frequency (HILF) extreme events during declared Major Event Days (MEDs). However, research studies have shown that these same HILF weather related events negatively impact system performance, customer satisfaction, and economic output sometimes with catastrophic consequences. This panel will explore the work that has been completed to date on developing Resiliency Metrics and provide some insights into industry level research that provides some insights into what factors and processes may be considered to measure a systems resiliency.
