Integrated approach to energy security and critical infrastructure in Croatia

The paper presents the concept and first results of the electrical engineering work package of the ongoing project “Energy security and critical infrastructure”, supported by the Croatian energy company HEP and Croatian Ministry of Defense. Participating institutions are from academic and private sector from multiple areas of science, including sociology, technology and policy planning. Work presented in the paper identifies critical infrastructures of interest, and demonstrates model based on complex network theory and probabilistic security analysis. The Croatian electrical power system risk is analyzed in order to indentify critical nodes and determine the optimal distribution of resources for risk reduction. There is potential to further improve this primarily deterministic and probabilistic analysis with use of multi-agent systems.
