Virtual-Flux-Based Passivation of Current Control for Grid-Connected VSCs
Heng Wu, Xiongfei Wang
Abstract
This letter proposes a passivity-based current control (CC) scheme for voltage-source converters, featuring a virtual-flux-based damper and a passive output admittance with a wide range of time delay involved in the CC loop. The admittance modeling and experimental tests validate the effectiveness of the approach.
