A hybrid modell for assessing resilience of electricity networks

Abstract

A hybrid model is used for quantification of three resilience metrics: robustness, rapidity and resilience loss. The approach is demonstrated in a case study on a municipal electricity distribution system. An overall conclusion from the case study is that the suggested method provides an overview of the resilience metrics of the electricity distribution system and that it allows the network operator to see for what levels of strain that they reach their targets concerning system resilience. It is also concluded that the presented approach can enable assessment of how decision variables, relating to the technical network as well as to the repair system, are impacting system resilience.
