Classes

YawOptimizationGeometric(fmodel[, ...])

YawOptimizationGeometric is a subclass of floris.optimization.general_library.YawOptimization that is used to provide a rough estimate of optimal yaw angles based purely on the wind farm geometry.

class floris.optimization.yaw_optimization.yaw_optimizer_geometric.YawOptimizationGeometric(fmodel, minimum_yaw_angle=0.0, maximum_yaw_angle=25.0)

YawOptimizationGeometric is a subclass of floris.optimization.general_library.YawOptimization that is used to provide a rough estimate of optimal yaw angles based purely on the wind farm geometry. Main use case is for coupled layout and yaw optimization.

See Stanely et al. (2023) for details: https://wes.copernicus.org/articles/8/1341/2023/

optimize()

Find rough yaw angles based on wind farm geometry. Assumes all wind turbines have the same rotor diameter.

Returns:

opt_yaw_angles (np.array): Optimal yaw angles in degrees. This array is equal in length to the number of turbines in the farm.
