Cyber-Physical Interdependency Modeling, Vulnerability Analysis and Mitigation for Power System Operation and Controls (slides)

Our current power grid infrastructure is being transformed into a cyberphysical energy system that heavily rely on communications/computer technologies for sensing, protection, control, and real-time operation. The strong coupling between cyber components and physical operations increase system vulnerabilities to potential cyber-related adverse events (e.g., cyber-attacks, `silent errors' due to manufacturing variability failures, hardware or software faults of monitoring devices due to code bugs, etc.). As a result, the reliable operation of the power system is highly dependent on the reliability of the associated cyber system. On the other hand, the malfunction of physical system components can also induce adverse effects on the cyber system availability and reliability. Consequently, monitoring, operation, risk analysis, reliability evaluation, and stability control of power systems should consider the interdependence between cyber and physical systems. In this proposed panel, current state-of-the-art methods of modeling, vulnerability analysis and mitigation for power system operation and control will be presented. We will bring together experts from academia, national labs, and utilities and have them presenting their perspectives and works on the topic™s emerging needs. The panel is aimed at engineers, scientists, researchers, educators, students, industrial utility experts, and other stakeholders who are engaged in PES community, research and education.
