Passivity-Based Dual-Loop Vector Voltage and Current Control for Grid-Forming VSCs
Heng Wu, Xiongfei Wang
Abstract
This letter proposes a passivity-based dual-loop vector voltage and current control method for grid-forming voltage-source converters (GFM-VSCs). A passive output impedance of GFM-VSC is guaranteed in both the voltage control mode and the current-limiting mode with a wide range of time delay. The frequency-domain analysis, simulation and experimental tests validate the effectiveness of the approach.
