floris - v4.4

FLORIS v4.4 introduces two new turbine operation models, the ControllerDependentTurbine model and the UnifiedMomentumModelTurbine, developed at TUM and MIT, respectively, to FLORIS. These provide exciting options for advanced modeling of how turbines operate when yaw misaligned and derated.

Also included is a beta feature for representing the variable operating cost (VOC) of a turbine and optimizing for net revenue given operating costs. Finally, a bug fix for wakes of turbines implementing active wake mixing is included.

floris - v4.3

FLORIS v4.3 updates package requirements and provides performance enhancements. Support for python v3.8 is dropped and the numpy requirement is stepped up to numpy v2 (that is, Floris v4.3 and above no longer supports numpy v1). Also, a beta feature to instantiate a FlorisModel from default values is added.

What's Changed

  • Bug fix: cast reference_wind_height to float by @Bartdoekemeijer in https://github.com/NREL/floris/pull/507

  • Bug fix: reset for zero yaw angles by @rafmudaf in 2fc9c544b89e5c00d7b49c581b1cc2bfb2759bae

    • In subsequent function calls to FlorisInterface.calculate_wake, the yaw angles were not reset when they are all zeros. This means that if initially the yaw angles are non-zero and then they’re all-zero, the non-zero yaw settings are retained.
