North Sea Transnational Grid
North Sea Transnational Grid
The European Wind Energy Association (EWEA) foresees that by the end of 2020 there will be circa 40 GW of installed offshore wind energy in Europe.
The North Sea Transnational Grid (NSTG) project aims to investigate the best ways of integrating large scale offshore wind power by the construction of a transnational transmission grid in the North Sea.

High voltage DC
As wind farms increase in size, and in distance from the shore, it is expected that high voltage DC (HVDC) connections will be one of the key elements in the construction of such grids.
One of the goals of the NSTG project is to develop new control strategies for converters operating inside a multi-terminal DC (MTDC) grid which could contain both current-source converters (CSC) and voltage-source converters (VSC).
Subsequently to the definition of the most suitable control strategies, a scaled-down MTDC converter system will be built and tested in a real time digital simulator (RTDS) to validate the models used in the design of the controllers.
High voltage DC connections will play an important role in a North Sea Transnational Grid. Therefore:
- North Sea Transnational Grid configurations with multi-terminal DC connections will be developed which integrate different AC and DC technologies.
- Technical and economic aspects of different Transnational Grid concepts will be evaluated.
- Control strategies of the North Sea Transnational Grid, a combination of wind farm and converter control, will be developed.
- This requires load flow as well as dynamic calculations and testing of multi-terminal converter control on a grid simulator.
- To determine the effect on the national grids, power flows will be studied, taking priorisation of wind, unit commitment and economic dispatch into account.
- Grid stability will be investigated focussing on two main aspects: rotor angle stability and voltage stability.
- Costs and benefits related to the realization of the North Sea Transnational Grid will be quantified, regulation and policy aspects that influence the success of a North Sea Transnational Grid will be investigated.
