Analysis of Cyber-Physical Attack In Transmission Systems

Abstract

Nowadays, most power systems in the world are facing the threats of both cyber and physical attacks. Sometimes., they may happen simultaneously in the new form called cyber-physical attacks which combine the cyber topology attacks and the physical topology attacks. In this paper, we will discuss three main cyber-physical attacks in a typical transmission system, which are line switching attack, outage attack and state estimation attack and their simulation results. By using open-source Python tool and Pandapower, we are able to perform modelling, simulation and analysis of electrical power systems.
