Abstract: In an islanded microgrid containing a number of grid-forming and grid-following converters (GFMCs and GFLCs), the GFMCs splits into at least two internally synchro- nized clusters under a sufficiently large transient disturbance, and the GFLCs interact with these clusters to manifest diversified behaviors, e.g., being absorbed into one of the aforementioned clusters, or temporarily joining one of the clusters, or forming a new cluster alone. Such behaviors are dependent on the GFLCs’ injected reactive power, network structure and edge weights. These factors can be adjusted to absorb more GFLCs into the dominant cluster of the microgrid. These findings are verified by a modified IEEE 39-bus power grid.

Speaker’s Bio: Jingxi Yang (Member, IEEE) received the B.S. and Ph.D. degrees in electrical engineering from Beijing Jiaotong University, Beijing, China, in 2014 and 2020, respectively. He is currently a Research Fellow with the Department of Electrical Engineering, City University of Hong Kong, Hong Kong. His research interests include the complex nonlinear behavior and stability of grid-connected power electronic converter systems. He was the recipient of the Outstanding Reviewer Award of the IEEE Transactions on Power Electronics in 2021 and 2024, and the Excellent Reviewer Award of the Journal of Modern Power Systems and Clean Energy in 2022. He is a member of the IEEE Power and Energy Circuits and Systems Technical Committee.
