Modeling, Control, and Security of Cyber-physical Power Systems
Abstract: While the advent of advanced power converter technologies, communication systems, and information technology has improved the efficiency and flexibility of energy supply, more challenges has been introduced to the security and control of smart grid systems. In this presentation, three aspects of modeling, control, and security of modern cyber-physical power systems will be discussed. First, cyber-physical attacks on power systems will be considered, where a cyberattacker can inject false data on measurements and result in a physical failure in the system. The impact of coordinated cyberattacks on failure of transmission and distribution systems will be shown using bi-level optimization problems. Next, control of cyber-physical power system will be covered and the role of distributed control in providing ancillary services to the grid will be demonstrated through case studies. Finally, the stability issues related to high penetration of converter-based renewable energy sources will be evaluated through classical control theories and case studies. It will be shown how the stability analysis can help system planners to find the stability margins and identify sensitive parameters that might negatively impact the performance of renewable energy sources in future smart grid systems.
Bio: Dr. Javad Khazaei received a Ph.D. degree in Electrical Engineering from University of South Florida (USF) in 2016 with focus on power and energy. He is currently an Assistant Professor at Pennsylvania State University, where he holds a joint appointment with the Electrical Engineering department at Penn State Harrisburg (PSH) and the Architectural Engineering department at Penn State University Park. His research is currently funded by the Department of Defense, Office of Naval Research (ONR) to develop distributed control algorithms for distributed energy resources in smart grids and cybersecurity research in power systems. He has experience in stability analysis of modern power systems, hardware development of microgrid systems and converter-based renewable energy sources as well as smart grid cybersecurity. His research interests include microgrid modeling, dynamic analysis of power converters in smart grids and buildings, application of distributed optimization in smart grids, cyber-physical power system security, renewable energy integration, and application of power electronics in power systems.
