Cyber Physical Power Electronics Dominated Systems Interdependency Modeling and Security

With the increased penetration of power electronics interfaced renewable energy sources that incorporate with cyber frameworks, the cyber-physical interactions have critical impacts for power system operation and control. Indeed, inverter-based resources (IBRs) are interconnected through communication networks, and the failures of IBRs or improper controls of them would cause significant concerns for system security. Therefore, power electronics dominated cyber-physical systems require special treatment and security controls. In this panel, the modeling of cyber-physical interdependency, power electronics system cyber security, impacts of IBRs at the distribution grid on bulk systems as well as practical experiences in operating power electronics dominated cyber-physical systems will be discussed.
