A major milestone has been achieved in the InterOPERA project: the release of the detailed functional specifications for the InterOPERA demonstrator.

This achievement reflects a long-term effort to set interoperability standards and mitigate risks in multi-vendor, multi-terminal HVDC technology for offshore wind integration.

This new booklet sets out the essential foundations for tomorrow’s HVDC building blocks, including:

• Coordinated DC grid control
• AC/DC converter stations
• DC switching stations 
• DC-connected power park modules 

Together, these specifications form a key step toward turning multi-vendor, multi-terminal HVDC systems into a practical reality.
