Abstract:
1. A method for the operation of a wind park with a plurality of wind energy plants, which each have one control unit, which controls and/or adjusts the wind energy plant in response to a received desired value for an electric variable, the method having the following steps: a supervisory control calculates and/or receives a currently permitted maximum value for the electric variable which the wind park is allowed to provide, the supervisory control determines a desired value for the electric variable for each wind energy plant and forwards the same to the wind energy plants, characterized in that the supervisory control determines the desired value for the electric variable for each one of the wind energy plants depending on the currently maximum and/or minimum available values for the electric variable of all the wind energy plants, and further wherein the desired value for the electric variable for a wind energy plant is determined as the currently maximum available value of the wind park, divided by the number of the wind energy plants, weighted with the quotient of the currently maximum available value for the electric variable of the wind energy plant and the arithmetic mean of the currently maximum available values for the electric variable of all the wind energy plants.
