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.

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.
