VVI-GFM: A Voltage Vector-Informed Grid-Forming Control for Postdisturbance Fast Synchronization Recovery

IEEE Transactions on Power Electronics
Maintaining synchronization stability after large grid disturbances is a vital requirement for grid-forming (GFM) converters. Existing enhanced GFM control strategies are often designed for a specific disturbance scenario, requiring extended recovery times or exhibiting frequency fluctuations.
