sentences:  Also, we can see the control scheme for the wind turbine in the machine side and simultaneously how we keep the Ids zero (the electromagnetic torque equation is linear).Modern large wind turbines are typically actively controlled to face the wind direction measured by a wind vane situated on the back of the nacelle.By minimizing the yaw angle (the misalignment between wind and turbine pointing direction), the power output is maximized and non-symmetrical loads minimized.
