To address the climate challenge and energy crisis, the European Union (EU) is transitioning to carbon neutrality, with wind power as the key driver. To fully exploit EU’s offshore wind resources, the strategy of constructing wind power hub has been devised and implemented recently, especially in Denmark. However, integration of numerous power converters in wind power hub forms a sophisticated system and becomes difficult to analyse. This PhyDAWN project aims to tackle these challenges by developing physics-informed data-driven modelling and stability assessment methodologies for wind power hub. Firstly, effective small-signal impedance model of voltage source converters has been developed considering different selection of reference frames, making modelling and stability analysis of large-scale converter integration possible. Next, data-driven aggregated model for multiple converters has been proposed, improving modelling scalability under insufficient data and enabling rapid stability assessment. Then, the stability of wind power hub has be assessed, revealing new types of instability phenomenon and providing insights for converter controller design. This project has been carried out by me, my supervisor at Aalborg University, and my secondment supervisor at KTH Royal Institute of Technology. Through our collaborations, this project has created novel knowledge for wind power hubs, leading to three papers published in top-tier journals and three papers presented at flagship conferences. A software toolbox is also being developed for fully exploitation of the research outcomes in the industry, which is expected to be released on Aug. 2025. Communication activities are also carried out as expected, expanding the impact of this project to the general public and committing EU’s carbon neutrality ambition. By applying the research outcomes of this project in the industry, the stability of offshore wind power hubs can be guaranteed, enabling future reliable integration of wind energy resources in the Europe. This project can also help raise the public awareness of climate change and energy crisis, and our current efforts on addressing these challenges by renewable energy.
