Complementing AC & DC Terminal Stability Analyses of MMC with Inner Loop Impedance
Chongbin Zhao, Qirong Jiang
Learning from two-level voltage source converters, the existing impedance-based stability analyses of modular multilevel converters (MMCs) primarily focus on system modes with fini…

New Perspectives and Systematic Approaches for Analyzing Negative Damping-Induced Sustained Oscillation
Chongbin Zhao, Qirong Jiang
Sustained oscillations (SOs) are commonly observed in systems dominated by converters. Under specific conditions, even though the origin of SOs can be identified through negative d…
