Posilování resilience prvků elektroenergetické kritické infrastruktury

Abstract

Electric power infrastructure is one of the key branches of critical infrastructure, and therefore it is necessary to ensure a high level of protection of its elements, especially by strengthening their resilience. This dissertation is devoted to strengthening the resilience of the electric power critical infrastructure elements with a focus on the transmission system. In the first part, attention is paid to the theoretical definition of the solved problem. The term resilience is explained here and a made description of the system of critical infrastructure and electric power critical infrastructure. The analytical part deals with the analysis of factors that determine resilience, the analysis of adverse events that could affect critical infrastructure elements and the analysis of approaches and tools that are used to evaluate and strengthen the resilience of critical infrastructure elements. The electricity subsector is constantly exposed to negative threats. Therefore, electricity elements must achieve a high level of resilience, which in the critical infrastructure system is defined as the ability to reduce the extent and/or duration of disruptive events, absorb negative incidents, adapt or quickly recover from potentially dangerous events. The core part of the work includes a proposal for a procedure for strengthening resilience, which consists of seven consecutive steps. In conclusion, the usability of this procedure is demonstrated in a case study of a selected element of the transmission system of the Czech Republic.
