Abstract
In one aspect, a method for selecting wind turbine generators in a wind park for a change in output power comprises providing a wind park comprised of a plurality n of wind turbines; selecting, on a non-spatial basis, n−1 or fewer wind turbines from the wind park for a change in power output; and changing power output of one or more of the selected n−1 or fewer wind turbines.
Claims15
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.
A system for selecting wind turbine generators in a wind park for curtailment of output power, said system comprising:
- a wind park comprised of a plurality n of wind turbines;
- and
- a controller, wherein the controller is operably connected to each of the n wind turbines and configured to send control signals to each of the n wind turbines and to receive signals from each of the n wind turbines, said controller having a user interface and said controller further configured to:
- select n−1 or fewer wind turbines from the wind park for power output curtailment based on a curtailment priority assigned to each of the n wind turbines, the curtailment priority being assigned to each of the n wind turbines based 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;
- and
- send one or more signals to curtail power output of one or more of the selected n−1 or fewer wind turbines.
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 on cumulative curtailment time of each of the n wind turbines, wherein the wind turbine with a lowest cumulative curtailment time gets assigned a highest curtailment priority and the wind turbine with a highest cumulative curtailment time gets assigned a lowest curtailment priority;
- selecting, on a non-spatial basis, 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.
