A novel current control strategy is proposed for voltage source converter connecting to weak grid using conventional current vector control with additional current error based voltage angle and magnitude compensations. For connecting to very weak AC network, conventional vector control is proved to be unstable, whereas the proposed current error based compensations can significantly improve system stability. In this way, the proposed control can still benefit from the presence of current closed-loop control without the need for control switching during large AC voltage variations. Comprehensive frequency domain model is established to analyze stability performance. Comprehensive time domain simulations are further carried out to validate its effectiveness and robustness by demonstrating its current control performance during a three-phase fault, multiple-converter situation and various grid strength conditions.
