Toward Developing Metrics for Power System Resilience

This paper will define resilience metrics and demonstrate their application on a sample set of end-use customers and distribution circuits. This set of metrics will be juxtaposed with those in common use for reliability and contextually situated within the grid modernization space. The initial presumption for the resilience metrics presented in this paper define a perfectly resilient system as one that can provide power 100% of the time throughout various scenarios. The metrics derived can be used to evaluate the capabilities of both existing and proposed infrastructure relative to the perfectly resilient system.
