Abstract:
The oscillation problem in DC distribution power system is becoming increasingly prominent as the system scale expands. Traditionally, virtual impedance methods are employed to reconfigure the impedance and eliminate the oscillation. However, traditional solutions are generally criticized for unsatisfactory stability, poor dynamic performance, and low scalability. To overcome these drawbacks, adaptive compensated virtual impedance (ACVI) methods are proposed. The proposed method can adapt to variable output power with significantly improved dynamic performance and stability. On top of this, an online source-side impedance estimation method is incorporated into the ACVI. It helps optimize the control parameters for adapting to different source impedances. The proposed method is implemented in a 48V DC distribution power system.

Speaker’s Bio:
Dr Minghao WANG received the B.Eng. from The Huazhong University of Science and Technology and The University of Birmingham in 2012, M.Sc. and Ph.D. from The University of Hong Kong in 2013 and 2017, respectively. He was a Postdoctoral Fellow and later a Research Assistant Professor at the Hong Kong Polytechnic University from 2018 to 2023. He is currently an assistant professor with the State Key Laboratory of Internet of Things for Smart City, University of Macau.
