In recent years there have been plans to develop large scale offshore wind farms in the North Sea. Dealing with variability of power from such wind farms is an important issue and should be addressed properly in the project developments. An HVDC connection between the offshore wind farm and Norway grid enables the offshore wind farms to benefit from the large hydro generation capacity of Norway for power balancing services. In this paper a connection scheme for an offshore wind farm in the Dogger Bank area, which makes use of the Norwegian hydro capacity for power balancing, is studied. It is demonstrated with PSCAD simulation how such interconnection can help in dealing with power fluctuations from the wind farm.
