Nested turbine type specific optimization
In this example, a nested optimization is performed accounting for the layout and the turbine types. The inner layer solves the layout optimization problem with a gradient-based solver, and the outer layer changes the turbine types with a gradient-free (random-search) solver. In this case, the boundaries are not specific to the wind turbine and a spacing and circular boundary contraints are used.
The objective function is to minimize the wake losses produced by neighbouring wind turbines.

Loading PyWake dependencies. We import the two turbines to use (Vestas V80 and the DTU 10MW reference turbine) as well as the site (IEA37) and the wake deficit model (IEA37SimpleBastankhahGaussian) to use for the optimization.

We now set up the two turbine types and define their basic paramenters such as diameter, hub height and CT curve. A TurbineTypes
class is created to merge the turbine objects to then feed into the wind farm model as WindTurbines
object.

.

'''Calculate the wake losses in %.'''
simres = wfm(x, y, type=np.asarray(type, dtype=int), **kwargs)
aep_ref = simres.aep().values.sum()
aep_nowake = simres.aep(with_wake_loss=False).values.sum()

Optimization set up
The first layer of the optimization takes the turbine positions and design variables as well as the spacing and boundary constraints.
[28]:

The second layer utilizes the optimized layout to then find the optimal turbine types that satisfy the objective function.

Given that wind turbine type 0 (V80) has significantly smaller diameter and hub height, the solver selects mostly that type. The type 1 causes larger wake losses due to larger rotor diameter. However, a sweet spot can exist that allows to minimize the wake based on the hub height difference of type 1.
