Structural Analysis and Internal Stability Enhancement of Virtual-Admittance-Based Cascaded GFMIs Under Unity Voltage-Feedback Decoupling
Stephen Arinze Obi, Ki-Hyun Kim, Jae-Jung Jung
Virtual admittance (VA) is widely used in cascaded voltage-control and current-control (VC-CC) grid-forming inverters (GFMIs) because it shapes the converter terminal behavior whil…

Decoupled Internal Energy Regulation and Inertial Response Provision for Grid-Forming Multilevel-Converter-Based E-STATCOMs
Ki-Hyun Kim, Yeongung Kim, Shenghui Cui +1
As power systems accommodate higher shares of renewable generation, short-term power imbalances become more frequent and can manifest as pronounced voltage and frequency excursions…

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…
