Step 3 – building the model

In this case, we want to implement a physics-based approach by building a mathematical relationship between the wind speed (m/s) and the amount of power generated (kW). The following Python code implements our model:

def wind_turbine_model(x):    if x<=4.5 or x>21.5:        return 0    return 376.936 - 195.8161*x + 33.75734*x**2 - 2.212492*x**3 + 0.06309095*x**4 - 0.0006533647*x**5

The following is a plot of the model with varying wind speed on the x axis:

Model of a wind turbine (wind speed versus generated power)

Note that this digital twin is only valid for a specific wind turbine model and we cannot generalize it to another. ...
