Measurement and evaluation of the power systems resilience against extreme events

The electrical energy systems are exposed to various dangers of all sizes and kinds, but it is still the case that the risks that result in the most severe damage are the high impact, low likelihood occurrences, which are often violent weather events. Their direct influences on the many strategically vital components generate massive malfunctions that are reflected in the degree of resilience of our systems, since they are the first reason that causes the level of resilience to decline severely, a fact that is presently the subject of much research in the field of electrical energy systems. In this paper, we will be involved in the evaluation of the degree of resilience to catastrophic events under various scenarios, defining the concept of resilience and its definition, modeling the various causes of its degradation, as well as classifying and citing some of these evaluation measures significant for the analysis of electrical networks. An evaluation measure has been proposed in this article and applied on two different scenarios, and we will compare the results with the results of a similar evaluation measure that was used in a previous study.
