Abstract: A method for operating a wind farm is provided. The method includes determining a wind condition, determining a wake-effect between at least two wind turbines forming at least a sub-set of the wind farm, each of the at least two wind turbines having a yaw system, and determining a desired yaw angle setpoint for each of the at least two wind turbines so that a total power production of at least the sub-set is expected to be increased compared to independently operating the yaw systems of each of the at least two wind turbines. Furthermore, a wind farm is provided.

Abstract: A method for noise-reduced operation a wind is provided. The method includes determining a wind speed during normal operation of the wind turbine and determining a weighted rotor speed setpoint for a rotor of the wind turbine so that a noise emission of the wind turbine for the wind speed is reduced compared to nominal noise emission of the wind turbine at the wind speed. Using the weighted rotor speed setpoint, a torque setpoint for a power conversion assembly connected to the rotor is determined. The torque setpoint is applied to the power conversion assembly to control the wind turbine.
