Abstract

To address a range of issues such as insufficient grid voltage support capacity due to increased renewable energy penetration, grid-forming (GFM) control has been widely discussed. Since the GFM voltage source converters (GFM-VSCs) have characteristics of controlled voltage sources, they are prone to overcurrent during grid faults. In this paper, the GFM control based on droop control with inertial segment (virtual synchronous generator control) is adopted, and an adaptive current-limiting strategy under grid faults is proposed. Finally, the effectiveness of the proposed adaptive current limiting strategy is verified by simulation. The result indicates that the current-limiting strategy in this paper can limit the current during grid faults to less than twice the rated current, while improving system stability during grid faults.
