Abstract [en]
This letter revisits vector voltage control (VVC) and finds that by introducing a P-E-q droop into the q-axis voltage reference, a conventional phase-locked loop (PLL) can effectively substitute the power synchronization control for replicating the power-frequency (angle) dynamics of grid-forming (GFM) inverters. Consequently, a simple GFM control strategy that retains the traditional PLL and VVC is proposed. In contrast to recently reported PLL-based GFM approaches, the method eliminates the need for virtual admittance control and offers higher stability robustness across a wide range of grid short-circuit ratios.
