Towards the Resilience Assessment of Electric Distribution System to Earthquakes and Adverse Meteorological Conditions

Abstract

The paper provides, as a first step, a critical, although not-exhaustive, review of the steps required for assessing the resilience of electric distribution systems to natural hazards, and identifies the required metrics and models still to be defined. Aiming to contribute towards that, the paper proposes an empirical-based analytical formula for estimating the expected damage frequencies to underground cable joints, when subjected to overheating. Empirical-based formulas for estimating the damage frequency to underground cables, subjected to earthquakes are also reported in the paper. The implementation of such models within a Decision Support System able to support resilience enhancement decision making processes is briefly illustrated in the paper.
