Progressive switching attacks for instigating cascading failures in smart grid

Abstract

In this paper we present a progressive strategy for applying a multi-switch cyber-physical attack on emerging smart grid systems. In contrast to a single switch attack, recently studied, we demonstrate how the additional degrees of freedom available to an opponent can be used to induce cascading failures throughout a power system in a stealthy way. A framework based on variable structure system theory is presented in which targeted attacks can be constructed. Attack execution is simulated on the New England 10-generator 39-bus test system using DSATools™ to demonstrate the potential of the approach to achieve high impact disruption.
