Transient Synchronization Stability Analysis and Enhancement Control for Power Self-Synchronization Control Converters

Electronics
Conventional grid-forming control often destabilizes voltage source converters (VSCs) in stiff grids, and transient synchronization instability will occur in the grid fault condition. Therefore, power self-synchronization control (PSSC) is first introduced for enhancing the small-signal stability of grid-forming control in the case of a short circuit ...
