Offshore Wind Accelerator Tender: HVDC OWFs - System Studies and Optimisation


Call for entries from companies and consortia interested in undertaking a study looking into the application of HVDC transmission for Offshore Wind Farms (OWFs) with a special focus on the development of generic models to facilitate system studies to be executed by developers in the early phases of a HVDC connected OWF project.


There is an increasing demand for safe and efficient grid connection of offshore wind farms using HVDC transmission technology. This study aims to provide improved insights into the application of HVDC transmission for OWFs, focusing on the following aspects:

  • Market review of the recent applications of HVDC transmission technology
  • Grid-code compliance and best practice guidelines for an optimised coordination of project tasks
  • Identification and evaluation of studies that can be reasonably performed by developers using generic models during development of a HVDC project
  • Coordination and interaction of large-signal and small-signal protection and control functions between HVDC converter station and OWF
  • Generic models to facilitate system studies to be executed in the planning & development phase and tender/bid phase of a project
  • Market consultation and assessment of potential further optimisation and cost reduction for HVDC converter stations
