Current-Limiting Control for Low-Voltage Ride-Through of GFM Converters Based on Capacity Constraints and Adaptive Virtual Impedance
Grid-forming (GFM) converters are prone to overcurrent during low-voltage ride-through (LVRT) because of their voltage-source characteristics and the limited overcurrent capability of power semiconductor devices. To address this issue, this paper proposes an LVRT current-limiting strategy based on capacity constraints...
