Dr. Li received the Bachelor degree from Tianjin University, China, in 2002, and PhD degree from the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, in 2006. In 2005, Dr. Li was a Visiting Scholar with Aalborg University, Denmark. From 2006 to 2007, he was a Postdoctoral Research Fellow in the Department of Electrical and Computer Engineering, Ryerson University, Canada. Dr. Li also worked at Rockwell Automation Canada as a R&D Engineer, before he joined University of Alberta in 2007.
Dr. Li is a Fellow of IEEE. He currently serves as Editor-in-Chief for IEEE Transactions on Power Electronics Letters. Prior to that, he was Associate Editor for IEEE Transactions on Power Electronics, IEEE Transactions on Industrial Electronics, IEEE Transactions on Smart Grid, and IEEE Journal of Emerging and Selected Topics in Power Electronics. Dr. Li served as the general chair of IEEE Energy Conversion Congress of Exposition (ECCE) in 2020. He is the AdCom Member at Large for IEEE Power Electronics Society (PELS) 2021-2023. Dr. Li received the Richard M. Bass Outstanding Young Power Electronics Engineer Award from IEEE PELS in 2013. He is recognized as a Highly Cited Researcher by the Web of Science Group.
Power electronic technology plays a vital role in today’s energy systems in terms of efficient energy conversion, integration of dispersed energy resources, electric vehicles, etc. My research areas mainly involve power electronics and their applications in renewable energy, distributed generation (DG), microgrid, electric vehicles, electric motor drives, and custom power devices (for power quality improvement). The research interests of my group include power converter topologies, pulse-width-modulation (PWM) techniques, modeling and digital control of power electronics, grid synchronization techniques, etc.
Grid integration of renewable energy systems (PV, wind) and energy storage systems.
Modeling, control and energy management of microgrid and active/smart distribution systems.
Ancillary services through grid-interfacing power converters.
High power converters and industrial drives.
Introduction to power system transient states. Power system voltage stability; PV and QV curve methods. Power system angular stability; transient stability and equal area criterion; steady-state stability and power system stabilizer. Electromagnetic transients in power systems, insulation coordination and equipment protection. Methods of power system design and simulation. Prerequisites: ECE 330 or E E 330, and ECE 332 or E E 332. Credit may be obtained in only one of ECE 433 or E E 433.
