• A robust, efficient, easy to use and flexible tool created to facilitate the optimised design of individual and clusters of offshore wind farms.
• A keystone of this optimisation is the precise prediction of the future long term wind farm energy yield and its associated uncertainty.

Scenario approach
45
• Organizing wind farm variants as scenarios• Scenario tree: hierarchy• Inheritance between branches and trees

What is a scenario?
46
• Wind climate
• Turbinepositions• Turbinetypes
• Model combinations• Model runs• Model parameters
