CAP Research Roulette
Seminars run by PhD students and postdocs with the Control and Power Group
Every week, an invited speaker gives a talk on a relevant topic (preferably in control and power) consisting of a 20-minute presentation followed by a 10-minute discussion. The content of talks can be
- conference contributions,
- initial research proposals,
- preparation for Early Stage Assessment/Late Stage Review, or
- tutorials on topics of the speaker's expertise.
After the talk, the participants can enjoy coffee and snacks (funded by the group) together in the Faraday Cage on EEE Level 6 and continue the discussion.
The CAP Research Roulette is open to everyone in the Control and Power Group. MSc students from Control Systems and Future Power Network Courses, who are willing to continue pursuing an academic career, are also strongly encouraged to participate.
Talk of the week
Title: Impedance Model of Grid-Connected Power Converters
Speaker: Yitong Li
Venue: MS Teams (Online)
Date and Time: Wednesday, 19/08/2020, 15:00-15:30
Abstract: In this talk, we introduce a new impedance modeling tool for designing the controller and analyzing the stability of power converters in power systems. Compared with the conventional all-in-one impedance model, the proposed tool provides a more intuitive and systematic impedance shaping solution. It is also able to capture the multi-control-loop coupling (interaction between control loops inside the converter) and the frame dynamics (interaction between the converter and the external grid). Additionally, the relationship between the conventional control and the virtual-impedance-based control is also revealed.
Biography: Yitong Li received the B.Eng degrees from Huazhong University of Science and Technology, China, and the University of Birmingham, UK, in 2015. He received his M.Sc degree in Future Power Networks from Imperial College London, UK, in 2016, where he is currently pursuing his Ph.D. degree. His current research interests include control of power electronic converters and analysis of power system dynamics.
