Hassan Haes Alhelou is with the Department of Electrical and Computer Systems Engineering of Monash University, Australia. He is a senior IEEE member, was listed in the Top 2% of scientists in the world by the Stanford University database in 2022, and the recipient of the Outstanding Reviewer Award from many journals, e.g., Applied Energy. He has participated in 15 international industrial projects globally. His research interests include power system dynamics and stability, operation and control, dynamic state estimation, and frequency control.Nasser Hosseinzadeh is the director of the Centre for Smart Power and Energy Research of Deakin University, Australia. With a PhD from Victoria University, Australia, prior positions include head of the Department of Systems at CQ University Australia, and of the Department of Electrical and Computer Engineering, Sultan Qaboos University, Oman. His main research focus is stability assessment of the power grid as impacted by inverter-based resources (IBRs). He is particularly working on the impact of IBRs on the power system strength, and the impact of a weak system on the operation of IBRs. He serves as a reviewer for several IEEE journals.Behrooz Bahrani is a senior lecturer at the Department of Electrical and Computer Systems Engineering at Monash University, Australia. He earned his PhD at the Ecole Polytechnique Federale de Lausanne (EPFL). He was a postdoctoral fellow at several institutions including EPFL, Purdue University, USA, Georgia Institute of Technology, USA, and Technical University of Munich, Germany. His research interests include control of power electronics systems, applications of power electronics in power and traction systems, and grid integration.
