Abstract
Methods and systems for reducing an output power of a group of wind turbines are provided. A measure of life usage by at least one component of each of a plurality of the turbines is determined, and is compared to a threshold value for life usage for the component. Power output is preferentially reduced from those turbines having at least one component for which the measure of life usage exceeds the corresponding threshold value.
