The importance of including dynamic inflow in the model used by the control algorithm is investigated in this contribution. A control setup consisting of a model predictive controller and an extended Kalman filter in conjunction with mechanisms to switch smoothly between partial and full load operation is presented.
Results, obtained from high-fidelity simulations, with and without dynamic inflow taken into account by the model-based control setup, show that the inclusion of dynamic inflow is important when operating in conditions close to the rated wind. The presented control setup does not employ collective pitch actuation during partial load operation, for e.g. load mitigation purposes, otherwise dynamic inflow would have been seen to also be of importance for all wind speeds below the rated wind speed.
