Standardizing Multi-Vendor High Voltage DC Grids for Offshore Wind Integration

energyTestedTRL 6

Imagine trying to build a giant Lego castle, but the bricks come from five different brands and don't snap together. This project creates a universal 'connector' system for massive electricity cables and converters. It ensures that equipment from different companies can work together to move wind power from the ocean to cities without crashing the grid.

The business problem

What needed solving

HVDC systems from different vendors are currently not interoperable, making it expensive and complex to build interconnected electricity grids. This creates a bottleneck for scaling offshore wind energy across Europe.

The solution

What was built

A real-time physical demonstrator, detailed functional specifications for subsystems, standardized simulation models, and multi-vendor cooperation agreements.

Who can put this to work

Energy Transmission
enterprise
Target: Transmission System Operator (TSO)

If you are a TSO dealing with the risk of vendor lock-in for HVDC grids — this project developed standardized models and interaction study processes that allow you to mix equipment from 4 different vendors. This ensures your grid can expand without being tied to a single manufacturer.

Renewable Energy
enterprise
Target: Offshore Wind Park Developer

If you are a wind park developer dealing with unstable power connections to shore — this project developed improved grid forming capabilities for converters. This helps your offshore wind farms maintain stability and integrate more efficiently into the European electrical system.

Electrical Equipment Manufacturing
enterprise
Target: HVDC Converter Vendor

If you are a vendor dealing with complex custom requirements for every new project — this project developed detailed functional specifications and common interfaces. This allows your products to be interoperable by design, reducing custom engineering costs for multi-terminal grids.

Frequently asked

Quick answers

What is the cost or price of implementing these standards?

Based on available project data, specific pricing or implementation costs are not provided; however, the project aims to make connecting HVDC systems more economic by removing the complexity of non-interoperable systems.

Can this be deployed at an industrial scale?

Yes, the project is designed for the European electrical system backbone, specifically targeting multi-terminal HVDC grids to transport massive offshore RES generation to shore.

How is the IP or licensing handled for the results?

Based on available project data, the project produces multi-vendor cooperation agreements and operational tools available to European stakeholders, though specific licensing terms are not detailed.

Does this comply with current energy regulations?

The project provides procurement solutions compliant with existing and future regulations, standards, and laws, and issues recommendations to grid codes.

How will the results be integrated into existing grids?

Integration is de-risked using a real-time physical demonstrator and validated through standardized models and simulation platforms.

Consortium

Who built it

The consortium is heavily industry-driven with an 84% industry ratio, comprising 27 industrial partners including 4 HVDC vendors and 8 TSOs. This high concentration of commercial players from 9 countries suggests the results are designed for immediate market application rather than academic curiosity, focusing on practical procurement and technical specifications.
