Current Reference Generation of Inverter-Based Resources During Asymmetrical Faults

This paper analyzes the current reference generation of inverter-based resources (IBRs) during asymmetrical faults. It is revealed that the existing current generation methods are insufficient in maximizing the fault current contribution under different current priority modes. In this paper, a novel current reference generation approach is proposed to address this problem while simultaneously ensuring compliance with converter current limitations and grid codes. Electromagnetic transient (EMT) simulations are given to verify the proposed method.
