Abstract
A method for controlling power output of a wind turbine generator in response to an anticipated change in wind speed is provided. The method includes sensing wind speed at a desired distance from the wind turbine generator in a direction of the wind. The method further includes controlling pitch of a blade of the wind turbine generator based upon sensed transient wind speed in advance of a change in wind speed at the wind turbine generator.

A method for controlling power output of a wind turbine generator in response to an anticipated change in wind speed, comprising:
- sensing wind speed at a desired distance from the wind turbine generator in a direction of the wind;
- determining a blade pitch command signal based upon a difference between a reference generator speed and actual generator speed;
- determining a feed-forward signal based upon wind turbine tower dynamics, in response to the change in the sensed upwind wind speed, and coupling the feed-forward signal to the blade pitch command signal to obtain a collective blade pitch command signal;
- and
- controlling pitch of a blade of the wind turbine generator based upon sensed transient wind speed in advance of a change in wind speed at the wind turbine generator.
