van den Broek, M.J. (author)In the current state of model-based wind farm flow control, the implementation of yaw-based wake steering based on steady-state models has demonstrated potential for improving wind farm power production. However, for realistic, time-varying wind directions, the dynamics of wake propagation may impact the effectiveness of wake redirection. This...doctoral thesis 2024

van der Hoek, D.C. (author), Van den Abbeele, B.H.L. (author), Ferreira, Carlos (author), van Wingerden, J.W. (author)Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is a recent innovation in the field of wind farm control, which employs individual blade pitch control to induce a helical velocity profile in a wind turbine wake. This forced meandering of the wake has turned...journal article 2024

Mr. Wang, Q. (author), Xu, Tangjie (author), von Terzi, D.A. (author), Xia, Wei (author), Wang, Zhenhai (author), Zhang, Haoran (author)In existing wind farms, the overall power output can be increased through yaw control. However, the cooperative control of start/stop, yaw and turbines positions is often overlooked, leading to wake superposition to downstream wind turbines and suboptimal power output. This paper proposes a synchronized optimized method that considers start...journal article 2024
