Building on the insights from a previous project, ‘Performance Analysis of Energy Islands with Multiple Interconnections’, the HVDC Centre has been contracted by National Grid Ventures to explore solutions to enhance the resilience and operational stability of HVDC-connected offshore wind farms. The study examines advanced strategies for managing DC faults and maintaining system performance in multi-terminal HVDC networks, utilising real-time simulation models.
Key areas of investigation include:
- System Modelling & Simulation: Updating and refining the Energy Island model to reflect realistic configurations and advanced grid-forming technologies.
- Energy Absorption Solutions: Assessing the feasibility of AC choppers to absorb excess energy during fault events.
- Protection Coordination: Evaluating the effectiveness of DC circuit breakers (DCCBs) and their interaction with converter-level protections.
The outcomes will provide practical recommendations for fault ride-through strategies, protection schemes, and integration guidelines, supporting the development of robust offshore HVDC networks for a Net Zero future.
