Robustness modelling and assessment of interdependent smart grids

Abstract

Abstract Future smart grids heavily rely on collaboration of two interdependent subsystems: the information and communication (ICT) system and the electrical system itself. The past has shown that malfunctions in one of the systems can propagate into the other system leading to widespread and heavy outages of power supply. Within this PhD project, a methodology for modeling, assessing and quantifying the Smart Grids’ robustness against occurrence of important unpredictable events is developed. Special attention is paid to the interdependencies between ICT and electrical subsystem and a particular novelty to existing approaches is the robustness quantification based on the current state of both subsystems allowing constant evaluation.
