Abstract: Regulating a power ramp rate of a wind park at a point of common coupling (PCC) between the wind park and a utility grid. The method comprises receiving a power reference for the wind park; determining the power ramp rate of the wind park as a function of the power output of each individual wind turbine in the park, wherein the power ramp rate of the wind park is based on the power ramp rates of the individual wind turbines and determining a corresponding plurality of power set-points for each wind turbine based on the power ramp rates and power reference. The corresponding plurality of power set-points is dispatched to the plurality of wind turbines for regulating the power ramp rate of the wind park in dependency of the power ramp rates of the plurality of wind turbines.

Abstract: A wind power plant system comprising: a plurality of wind turbine generators each having a corresponding generator controller, and a power plant controller for controlling the power generated by the wind power plant system; wherein at least some of the plurality of generator controllers are each configured to: generate a model that indicates the thermal capacity of one or more components of the wind turbine generator, determine power capacity data from the model, said data relating to: at least one reactive power supply level and a corresponding time limit for which that reactive power supply level may be maintained, and transmit to the power plant controller the determined power capacity data, wherein the power plant controller is operable to receive the power capacity data from the plurality of generator controllers and to transmit respective power references to the plurality of generator controllers to control the power generated by the wind power plant system.
