Biography
Chi K. Michael Tse received the BEng degree with first class honors and the PhD degree from the University of Melbourne, Australia. He is presently Associate Vice-President (Strategic Research) and Chair Professor of Electrical Engineering at City University of Hong Kong. He has been appointed to honorary professorship and distinguished fellowship by a few Australian, Canadian and Chinese universities, including the Chang Jiang Scholar Chair Professor with Huazhong University of Science and Technology, Honorary Professor of Melbourne University, Distinguished International Research Fellow with the University of Calgary, and Distinguished Professor-at-Large with the University of Western Australia. His research interests include complex network applications, power electronics and nonlinear systems. The IEEE Circuits and Systems Society awarded him the Charles A. Desoer Technical Achievement Award in 2022 in recognition of his outstanding contributions and continued leadership in the development of research in complex behavior of power electronics and energy systems. He is an IEEE Fellow (elected 2005) and an IEAust Fellow (2009)
Challenges in Power Electronics Penetrated Power Grid

Abstract
The penetration of power electronics into power generation and distribution systems has deepened in recent years, as prompted by the increasing use of renewable sources, the quest for higher performance in the control of power conversion, as well as the increasing influence of economic plans that necessitate power trading among different regions or clusters of power distribution. As a result of the increased use of power electronics for controlling power flows in power systems, interactions of power electronics systems and conventional synchronous machines’ dynamics would inevitably cause stability and robustness concerns, which can be readily understood by the coupling effects among interacting dynamical systems of varying stability margins (or transient performances) [1]. In this talk, we discuss the various problems of power electronics penetration into power grids and the implications on the stability and robustness of power networks and examine the current progress and future direction of research in power systems amidst the extensive deployment of power electronics.
