Abstract:
A huge amount of wind power, 30-60 GW, is foreseen in the northern part of the North Sea.
These wind farms have to be connected to the national grids of five different countries in a
flexible and economical way. Individual connection is straightforward but for several reasons
possibly not the best choice. A high capacity North Sea Transnational Grid connecting wind
farms to the national grids and at the same time connecting the national grids together, may
well be a better solution for reasons of energy efficiency, availability, controllability, lower
costs and the possibility to trade/exchange electricity .
The objective of the North Sea Transnational Grid project is to determine the best solution
(modular, flexible, most cost effective) for a high capacity transnational offshore grid,
connecting all future wind farms in the northern part of the North Sea to the Netherlands,
UK, Norway, Denmark and Germany. Different technical solutions for a Transnational Grid
will be investigated. For the most promising solution a multi-terminal converter controller
will be developed and tested. A second objective is to determine the effects of the
Transnational Grid on the national grids, in which the operating strategy of the
Transnational Grid will be developed to regulate power exchange correctly and avoid
congestion. Moreover, the effect of the Transnational Grid on national grid stability will be
investigated. The costs, benefits, policies and regulations related to realization of the North
Sea Transnational Grid will also be investigated and compared to alternative scenarios.
This report summarizes the main results of the project by describing the results of the main
work packages. More detailed information can be found in the technical reports prepared
for each work packages. The final section contains a list of these reports and the papers
prepared in the NSTG project. The reports and the public papers can be downloaded from
the NSTG website: www.nstg-project.nl
This project was financially supported by the Ministry of Economic Affairs under the Energie
Onderzoek Subsidie - Lange Termijn (EOS-LT) programme, executed by AgentschapNL.
