Analysis of the smart grid’s transient behavior in detecting cyber-physical attacks

Attacks on smart grids in the power system can result in large-scale failures if not managed in a speedy manner. Many bad data detection algorithms have been developed to limit cyber-physical attacks and their potential threats. We model in this article, the transient response of a system whose line and load get disconnected and compare it with the transients of an increased power injection in the system. The purpose is to show that even though state estimation will not detect the difference between an actual attack on the line and an increase in the power generation, monitoring the transient behaviors of both cases shows clear differences and presents a tool in detecting cyber-physical attacks on smart grids.  Report in pdf
