Offshore grid topology optimisation with a geographical information system

A novel methodology is investigated to identify and optimise large scale offshore grid topologies connecting multiple wind farms countries with each other. Geographical Information System (GIS) setup cluster create a permissive graph topology. Its purpose propose layouts potential hub locations landing points bottom-up in fully analytical toolchain, while avoiding manual scenario building. coupled market model performs the investment optimisation into new lines on GIS created graph. This two-step procedure demonstrated at example of Baltic Sea Region for target year 2040. It can be found, that future benefit from bundled transmission paths many clustered farms. sensitivity analysis reveals topology results are sensitive farm location assumptions pre-defined interconnectors or hubs. Not least, capability onshore integrate influx power level detail it modelled in, directly reflects grid. concluded optimising quest pan-European which benefits heavily geo data based pre-processing GIS.
