Cyber-Physical Systems Security of Smart Grid

The electric power grid is a highly automated network that uses a variety of sensors, information and control systems, and communication networks for the purpose of monitoring, protection and control of the grid. The recent findings, as documented in federal reports and in the literature, indicate the growing threat of cyber-based attacks in numbers and sophistication on the nation’s electric grid and other critical infrastructure systems. Therefore, cyber security of the power grid — encompassing attack prevention, detection, mitigation, and resilience — is among the most important research issues of today and in the future.

Our research focus:

Cyber-physical systems framework for risk modeling and mitigation of cyber attacks on the power grid that accounts for dynamics of the physical system, as well as the operational aspects of the cyber-based control network.

 

Vision: "Transform the Grid from Fault-Resilient to Attack-Resilient"

 

Research Objectives & Highlights:

  1. Vulnerability Analysis: Systematic evaluation of cyber vulnerabilities in the SCADA and other automation systems of the power grid.

  2. Impact Analysis: Quantifying the impact of successful cyber attacks on the operation of the power grid.

  3. Risk Modeling: Quantitative methodology for evaluating the risk due to cyber attacks, including coordinated attacks.

  4. Risk Mitigation: Attack-resilient protection and control algorithms, and model-based intrusion detection algorithms to detect and mitigate cyber attacks.

  5. Tesbed & Validation: An integrated testbed, called PowerCyber, that interfaces industry-grade SCADA with real-time power system simulator (RTDS), with associated power system devices (relays, PMUs) and energy management system (EMS) software, grid communication and security technologies. The testbed provides a realistic platform to conduct cyber attack-defense studies. PowerCyber Testbed Flier
