Cyber-Physical Systems (CPS) Security of the Smart Grid

Modern electric power grid is a complex cyber-physical critical infrastructure that forms the lifeline of modern society, and its reliable and secure operation is of paramount importance to national security and economic well-being. The electric power grid, as of today, is a highly automated network, wherein a variety of sensors, control logics, computing systems, and communication networks are interconnected to the physical grid for ensuring reliable, safe, and efficient operations of the grid. In recent years, several authoritative sources have acknowledged the rapidly evolving nature of cyber threats to the power grid, and the urgent need to protect the grid against them.

Vision:

"Transform the Fault-Resilient Grid of today into a Secure and Attack-Resilient Grid of the Future"

Our research focus:

Our research articulates a holistic cyber security framework encompassing attack deterrence, prevention, detection, mitigation, resilience, and attribution. In particular, it focuses on the development of cyber-physical system algorithms, techniques, and tools for cyber risk modeling, risk mitigation, and attack-resilient monitoring, protection, and control that account for dynamics of the physical system as well as the operational aspects of the cyber and control network. Our focus is also on the development of a realistic CPS Security Testbed and experimental evaluation/validation of the cyber security solutions bridging the gap between academic research and industry practice.

Research Objectives & Highlights:

  1. Vulnerability Analysis: Systematic evaluation of cyber vulnerabilities in the substation, SCADA, and control center of the power grid.

  2. Impact Analysis: Quantifying the impact  cyber attacks on the operational security and stability of the power grid.

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

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

  5. Tesbed & Experimentation: An integrated CPS security testbed, called PowerCyber, that interfaces industry-grade SCADA with real-time power system simulator (RTDS), with industrial 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 evaluations and cyber security training. PowerCyber Testbed Flier
