The Challenge of Designing an Offshore Wind Farm

One of the most challenging tasks for wind farm developers is the optimisation of offshore wind power plants. Large offshore wind farms and wind farm clusters, such as those in the German Bight or on the Dogger bank, change the wind climate itself and make this optimisation task even more demanding. During the process of wind farm optimisation, hundreds of variations are considered and need to be managed, documented and benchmarked.

Wind & Economy: Optimised Offshore Wind Farms

Our new software tool, Wind & Economy, supports your challenging work with the seamlessly integrated modelling of wind climate, large scale and localized wind farm effects, electrical loss calculations and derivation of economic key figures.

A clearly organized workflow supports you in the management of the set of all wind farm variations ever to be considered during your project. Using LCOE, the Levelized Cost of Energy, as an economic performance key indicator helps you to benchmark different approaches and select your optimised design.

In addition, the detailed knowledge of the uncertainties of energy production and LCOE supports the management of financial risks. Leading edge meteorological and wind farm models, taken together with a consideration of the uncertainty of energy production and the cost of energy, make your results waterproof and bankable.

Optimisation Support

Having hundreds of variations of the wind farm layout is not rare during the optimisation process of offshore wind farms. In order to support you in handling these different configuration options as efficiently as possible, we have defined a workflow which organizes many different farm variants in a development tree.

For this purpose, Wind & Economy defines farm “scenarios” consisting of wind climate, turbine types, hub height, models used to calculate the energy production, electrical grid layout and economic parameters.

These scenarios, organized in trees, help you in keeping track of your valuable work and the development process. Comparative reporting of the results from a number of scenarios supports you in selecting the right track towards your optimised wind farm.

GIS Integration for Offshore Wind Farms

Many tasks which must be performed in order to optimize offshore wind farms are well supported by Geographical Information Systems, GIS. To benefit from this approach, we have included an open source GIS, the QGIS software, into the Wind & Economy workflow as one possible frontend.

By using this approach, you will be able to:

  • edit turbine layout
  • visualize local and large-scale wind resources and energy production
  • edit turbine types and other parametersBerechnung der elektrischen Verluste
  • optimise the cable layout
  • calculate electrical losses
  • select grid connection options
  • consider environmental protection areas
  • include additional information such as maps of water depth, exclusion areas, shipping lanes and others into your planning work
