Energy islands represent a new approach to integrating large-scale offshore wind into interconnected power systems. The Bornholm Energy Island is planned as one of the world’s first energy islands, collecting at least 3 GW of offshore wind generation and connecting it to Denmark and Germany through HVDC links. The project is also intended to pave the way for future energy hubs, including developments in the North Sea, while creating opportunities for sector coupling through technologies such as Power-to-X.
At the Technical University of Denmark (DTU), the Offshore Energy Hubs research project investigates alternative electrical architectures for such systems, including AC, DC, and hybrid hub topologies with multi-terminal HVDC networks. This presentation focuses on the real-time modelling and analysis of these concepts using the RTDS Simulator. The RTDS platform is used to validate system and control models under realistic operating conditions and to support their progression toward hardware-in-the-loop testing, thereby increasing the technology readiness of the developed solutions.
