In order to reduce the wake loss in the wind farm and enhance the whole field power generation, the whole field cooperative control based on yaw control has become a current research hotspot. To address issues such as existing studies not fully considering the dynamic changes in incoming flow and the time-lag effects of wind farm flow, a high-fidelity large eddy simulation method is used to numerically simulate the wind farm flow, and the flow delay time between units is determined by the spatial and temporal correlation between the flow field and the power of the neighboring units. Considering the flow delay time of the flow field, a dynamic yaw control strategy is proposed for the wind turbine under the turbulent inflow conditions. The large eddy simulation results show that the total power generation of the wind turbine array under static yaw and optimal dynamic yaw control is increased by 11.5% and 12.5%, respectively, compared with that under no yaw control. Compared to the static yaw control, the wake development between the wind turbine array is more fully developed and the wake velocity recovery is faster under dynamic yaw control.
