A novel wake control approach for power generation improvement of three wind turbines in a wind farm

The total power generation of a wind farm is significantly affected by the adverse wake generation of upstream wind turbines on the aerodynamic performance of the downstream wind turbines. This paper aims to provide a novel hybrid wake control strategy to improve the power generation of horizontal-axis wind turbines in a wind-farm layout. A numerical simulation based on the actuator line method with large eddy simulation (ALM–LES) is performed to investigate the airflow around three-dimensional National Renewable Energy Laboratory (NREL) 5 MW turbines in a three-by-one layout. The yaw angle (θ)(θ) and tilt angle (ϕ)(ϕ) of the wind turbines are in the range of (−30 deg<θ<30 deg)(−30 deg<θ<30 deg) and (0<ϕ<35 deg)(0<ϕ
