Abstract
A method of controlling a wind turbine includes obtaining weather data indicative of one or more weather conditions at the wind turbine, estimating wake profiles based on the obtained weather data, estimating far-field sound propagation in a direction of a noise sensitive site based on the estimated wake profiles, generating a yaw signal, wherein the yaw signal controls the yaw of a nacelle relative to a tower of the wind turbine, estimating a noise level at the noise sensitive site, and adjusting the yaw signal if the estimated noise level at the noise sensitive site exceeds a threshold noise level.
