Grid-forming (GFM) converters are required to meet multiple operational and control demands in power systems. Under grid fault conditions, maintaining transient synchronization stability (TSS), suppressing fault overcurrent, maximizing fault current support, and preserving voltage source characteristics are all of critical importance. However, achieving effective coordination among these objective...
