Abstract
Electric power systems are critical infrastructures subject to the possibility of extraordinary events with high societal consequences. Although such possibilities are often associated with very low probabilities of being realized, it is nevertheless crucial to be able to identify and understand the vulnerabilities of power systems related to extraordinary events. The objective of the work presented in this article is to establish a methodological basis for vulnerability analysis that is complementary to conventional risk and reliability analysis of power systems. It presents a comprehensive framework of definitions, indicators and methods that can be used to classify, analyse and monitor vulnerabilities in power transmission and distribution systems. Its main components include (1) a conceptual framework of definitions that forms the basis for understanding and classifying vulnerabilities, (2) an assessment methodology for identifying vulnerabilities related to extraordinary events and barriers to mitigate them, and (3) vulnerability indicators for quantifying and monitoring power system vulnerabilities. The applicability of the vulnerability analysis framework is demonstrated through several studies of real power systems. Moreover, the concept of power system vulnerability elaborated in this article is also related to the concept of power system resilience.

Motivated by the vital role of the electric power system and the crucial need to better understand the vulnerabilities of power systems, the objective of the work presented in this article is to establish a methodological basis for analysing vulnerabilities related to extraordinary events in power systems
Dependence of other critical infrastructures on electricity supply Outdoor temperature development needs to reflect the purpose of the indicators and should be carried out in close collaboration with stakeholders; 2) the indicators should be able to give insight into vulnerability related to extraordinary events; 3) they should quantify aspects associated with one of the four dimensions of vulnerability in isolation; and 4) they should be selected based on the aspects identified as relevant for the system of interest
Summary
Society is increasingly dependent on a secure electricity supply to maintain its functionality and cover basic needs. The article describes a comprehensive framework of definitions, indicators and methods that can be used to classify, analyse and monitor vulnerabilities in power transmission and distribution systems relevant for extraordinary events and applicable for both planning and operation purposes [28,29]. This framework has been developed and thoroughly tested on real power systems over a number of years.
