A Flexible Framework to Investigate Cascading in Interdependent Networks of Power Systems

This paper introduces a flexible framework to analyze cascading effects in the interdependent power and information and communications technology (ICT) networks that that comprise a power system. This framework supports integration of interdependencies between the power grid and various ICT networks, but also of domain-specific intra-dependencies of these different subsystems. The framework is applied to model a simple example system, where three failure scenarios are defined and simulated to showcase the applicability of the framework for the investigation of cascading effects.
