Abstract:
1. A method of selecting wind turbine generators in a wind park for curtailment of output power, said method comprising: providing a wind park comprised of a plurality n of wind turbines; assigning a curtailment priority to each of the n wind turbines based at least partially on one or more non-spatial factors, wherein said one or more non-spatial factors comprise at least one of noise produced by a specific wind turbine, distance from a specific wind turbine to a sound sensitive location, expected lifetime of a specific wind turbine's pitch system, contractual requirements, electrical limitations of the wind park, need to perform maintenance on a specific wind turbine, pitch movements of a specific wind turbine, or cumulative curtailment time of a specific wind turbine; selecting n−1 or fewer wind turbines from the wind park for power output curtailment based on the curtailment priority assigned to each of the n wind turbines; and curtailing power output of one or more of the selected n−1 or fewer wind turbines.
