Mitigation of Structural Harmonic Instability in Virtual Admittance-Based Grid-Forming Inverters via Mimicking Skin Effect
Jaekeun Lee, Jae-Jung Jung, Shenghui Cui
The virtual admittance-current controller (VA-CC) scheme is widely employed to emulate an equivalent inductance in front of the internal voltage source of grid-forming inverters. H…

Transient Stability Analysis of Grid-Forming Converters with Current Limiting Considering Asymmetrical Grid Faults
Seongyeon Kim, Ki-Hyun Kim, Shenghui Cui +1
Under asymmetrical faults, analyzing the transient stability of grid-forming voltage-source converters (GFM-VSCs) becomes essential because their behavior fundamentally differs fro…
