Negative Resistance Caused by Intra-Loop Coupling in Virtual-Admittance-Based Grid-Forming Control
Jaekeun Lee, Minwoo Jeong, Jae-Jung Jung +2
This paper addresses the harmonic instability problem of the virtual-admittance (VA)-based grid-forming control. It is revealed that the intra-loop coupling among the VA control, t…
Control of Grid-Forming VSCs: A Perspective of Adaptive Fast/Slow Internal Voltage Source
Heng Wu, Xiongfei Wang
Grid-forming (GFM) capability requirements are increasingly imposed on grid-connected voltage-source converters (VSCs). Under large grid disturbances, GFM-VSCs need to remain stabl…
Stability and Sensitivity Analysis of Multi-Vendor, Multi-Terminal HVDC Systems
Yicheng Liao, Heng Wu, Xiongfei Wang +3
The stability of multi-vendor, multi-terminal HVDC systems can be analyzed in frequency domain by black-box impedance models using the generalized Nyquist stability criterion. Base…
Impedance-Based Stability Analysis for Interconnected Converter Systems with Open-Loop RHP Poles
Yicheng Liao, Xiongfei Wang
Small-signal instability issues of interconnected converter systems can be addressed by the impedance-based stability analysis method, where the impedance ratio at the point of com…
Design-Oriented Transient Stability Analysis of PLL-Synchronized Voltage-Source Converters
Heng Wu, Xiongfei Wang
Differing from synchronous generators, there are lack of physical laws governing the synchronization dynamics of voltage-source converters (VSCs). The widely used phase-locked loop…
Design-Oriented Transient Stability Analysis of Grid-Connected Converters with Power Synchronization Control
Heng Wu, Xiongfei Wang
The power synchronization control (PSC) has been increasingly used with voltage-source converters (VSCs) connected to the weak ac grid. This paper presents an in-depth analysis on…
