Example 02b: Wind Farm Realistic Inflow (Precomputed FLORIS)

Example 02b: Wind Farm Realistic Inflow (Precomputed FLORIS)#

Description#

This example is identical to 02a_wind_farm_realistic_inflow with the exception that the precomputed wake method is used to speed up the simulation. The configuration sets wake_method: precomputed in the wind_farm component. This example automatically generates the necessary input files in the centralized examples/inputs/ folder when first run.

Note the caveats to using this method from the docs:

In contrast to wake_method: dynamic, this method pre-computes the FLORIS wake deficits for all possible wind speeds and power setpoints. This is done by running for all wind speeds and wind directions (but not over all power setpoints). This is valid for cases where the wind farm is operating in the following ways: - all turbines operating normally (maximum power) - all turbines off - following a wind-farm wide derating level

It is in practice conservative with respect to the wake deficits, but it is more efficient
than running FLORIS for each condition at each time step.  In cases where turbines are:
    - partially derated below the curtailment level
    - some, but not all, turbines are off
this is not an appropriate model and the more general `wake_method: dynamic` should be used.
