Sammendrag
A planning tool for clustering and optimised grid connection of offshore wind farms is presented and described in some detail. This tool is suitable for high level, strategic planning of clustering and grid connection of future offshore wind farms that are planned in the proximity of each other. This tool is an upgraded version of a previously developed tool for offshore grid expansion planning. The use of the upgraded tool is demonstrated with an example that considers the Kriegers Flak area, with results indicating benefits of interconnecting wind farms across country borders and using a hybrid AC and DC transmission system to shore.
