Towards a Systemic Asset Characterization of Electrical Systems for Multi-Risk Resilience

Traditional reliability analysis tools for electrical systems must be advanced to represent the potential impacts from climate change and other natural hazards and must embed system-of-systems approaches to account for critical infrastructures’ (CIs) interdependencies. The Italian project RETURN, funded by the PNRR, within the activity-line “Multi-Risk Resilience Assessment of Critical Infrastructures” is adopting an interdisciplinary and holistic approach for developing impact modelling methods with an all-hazards perspective. The paper provides an overview of the methodology under development towards the systemic modelling and analysis of CIs, including the electrical transmission and distribution systems, aiming to support decision making processes targeting multi-risk resilience.
