| Abstract |
Recently, Grid-forming (GFM) converters have gained significant attention for their ability to enhance power system stability during disturbances. However, conventional current-limiting strategies lack sufficient consideration for preserving GFM capability under current-limited conditions. To address this issue, this paper proposes a novel current-limiting strategy that simultaneously ensures accurate current limitation and preserves GFM capability. The proposed method minimizes deviations in the converter terminal voltage by incorporating a PCC voltage-based current-limiting condition in real time. This approach allows the GFM converter to preserve its natural response-driven GFM capability to the greatest extent possible within a given current limit. Experimental results validate the superior performance of the proposed method compared to existing methods. |
