Abstract
A method for controlling a ramp rate of a wind farm is described. The method includes predicting an initial predicted power to be output by a wind farm including a wind turbine.
Claims19
A method for controlling a ramp rate of a wind farm that includes at least one wind turbine, said method comprising:
- estimating an initial predicted power output limit as a function of ramp rate and an instantaneous power output, said estimating an initial predicted power output limit comprising;
- estimating a first predicted power output limit as a function of a first instantaneous power output;
- estimating a second predicted power output limit as a function of a second instantaneous power output;
- selecting a lower of the first and second predicted power output limits;
- and
- comparing a second instantaneous power output to the lower of the first and second predicted power output limits;
- and
- controlling a ramp rate of the at least one wind turbine based on the lower of the first and second predicted power output limits.

A controller configured to facilitate control of a ramp rate of a wind farm that includes at least one wind turbine, said controller comprising:
- an initial array module configured to generate a plurality of predicted power output limits;
- a minimum module configured to select a lowest value of the plurality of predicted power output limits;
- an adder module configured to determine a difference between an instantaneous power output and the lowest value of the plurality of predicted power output limits;
- and
- at least one module configured to control a ramp rate of the at least one wind turbine based on the lowest value of the plurality of predicted power output limits.
2 more elements
A wind farm comprising:
- at least one wind turbine;
- and
- a controller coupled to said at least one wind turbine and configured to control a ramp rate of said wind farm, said controller comprising:
- an initial array module configured to generate a plurality of predicted power output limits;
- a minimum module configured to select a lowest value of the plurality of predicted power output limits;
- an adder module configured to determine a difference between an instantaneous power output and the lowest value of the plurality of predicted power output limits;
- and
- at least one module configured to control a ramp rate of the at least one wind turbine based on the lowest value of the plurality of predicted power output limits.
