Active Support Control Strategy for Virtual Flux in Offshore Wind Power Flexible Direct-Current Transmission

Le résumé fourni par la source

The integration of large-scale offshore wind power into the grid poses challenges to the frequency and voltage stability of the receiving end of the power system. The limitations of relying solely on active support strategies from onshore converter stations are received significant attention. To address this, a novel model predictive control strategy is proposed, leveraging virtual flux coupling between onshore and offshore converter stations. This strategy establishes a flux relationship for flexible DC voltage control and optimizes energy balance between the wind farm and the power grid. By incorporating a rotating internal electromotive force under virtual flux, the proposed method achieves effective frequency and voltage regulation for source-grid interaction. The effectiveness of this strategy is validated through a hardware-in-the-loop validation platform for Typhoon MYWAY404.
