The Resilience of Active Electric Distribution Systems 

Power system reliability refers to the probability of the satisfactory provision of power and energy to meet load demands and the ability to withstand disturbances. It is related the low impact/high-frequency events and is generally measured by several interruption indices defined by relevant standards. Power system resilience is the ability to limit the extent, severity, and duration of system degradation following extreme (low-frequency/high-impact) events. Initial resiliency concerns were generally focused on the transmission system. On the other hand, large-scale penetration of renewable energy resources and energy storage systems into the distribution grid has increased the role of electric distribution systems in the power delivery network. In this regard, planning and operation of distribution system resilience are getting more interest from utilities and researchers with the dramatically increasing number of natural extreme events (e.g., hurricanes, earthquakes, and floods) and man-made attacks (cyber and physical attacks). There are several efforts for developing control and operation methods and planning strategies to improve grid resilience against such events. This presentation aims to provide a detailed overview of distribution system resilience, the classification, assessment, metrics for measuring resilience, possible methods for enabling resilience, and the associated challenges.
