Impedance-Based Approach for Stability Analysis in Inverter-Dominated Power Systems
Dr Yue Zhu, City University of Hong Kong
Abstract: The high and growing penetration of inverter-based resources (IBR) in modern power systems has brought challenges to system stability, especially to small-signal stability reflected by the concerning oscillations. This seminar will discuss the impedance-based approach for oscillation root-cause tracing, tuning, and early warning. The new approach establishes the relationship between the impedance model and the conventional state-space model and opens up the path of using black-box impedance model to extract useful insights similar to those obtained from the white-box model. New technologies, such as using a single perturbation to restore the whole-system impedance model based on a hybrid data/model-driven method will also be introduced.
Speaker’s Bio: Dr. Yue Zhu is an Assistant Professor in the Department of Electrical Engineering, City University of Hong Kong (CityUHK). Prior to joining CityUHK, He was a Postdoctoral Research Associate in Department of Electrical and Electronic Engineering, Imperial College London. He received his B.Eng. and M.Sc. degrees from Zhejiang University and his PhD degree from Imperial College London. His research focuses on stability, dynamics, and control of large-scale inverter-dominated power systems, addressing critical challenges including system oscillations, data-driven impedance identification, and system strength assessment for connections of new inverter-based resources.
