Cyber-physical security testbed for substations in a power grid

Abstract

The physical system of the power grids relies on the cyber system for monitoring, control, and operation. As a result, the reliable operation of power grids is highly dependent on the associated cyber infrastructures. The integrated cyber and physical system of power grids creates a large and complex infrastructure. Due to the high penetration of Information and Communications Technology (ICT), Supervisory Control And Data Acquisition (SCADA) systems are highly interconnected with one another, resulting in higher vulnerability with respect to cyber intrusions. Recent reports indicate that cyber-attacks are increasingly likely for the critical infrastructures, e.g., control centers, nuclear power plants, and substations. These attacks may cause significant damages on the power grid. Cyber security research for the power grid is a high priority subject for the emerging smart grid environment.
