A method for the operation of a wind park with a plurality of wind energy plants, which each one have one control unit at a time, which can control and/or adjust the wind energy plant in response to a received desired value for an electric variable, the method having the following steps: a higher order control calculates and/or receives a currently permitted maximum value for the electric variable which the wind park is allowed to provide, the higher order 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 higher order control determines the desired value for each one of the wind energy plants depending on the currently maximum and/or minimum available values of all the wind energy plants.

What is claimed is: 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. 2. The method according to claim 1, characterized in that the supervisory control determines each desired value of one of the wind energy plants depending on the currently maximum and/or minimum available values of the wind energy plants and the preset currently maximum permitted value for the electric variable. 3. The method according to claim 1, characterized in that the desired values for each wind energy plant are calculated when the currently maximum available value of the wind park is smaller than or equal to the currently maximum permitted value of the wind park. 4. The method according to claim 1, characterized in that the desired values for each wind energy plant are calculated when the currently maximum available value of all the wind energy plants is greater than or equal to the maximum permitted value. 5. The method according to claim 1, characterized in that when the desired value of one of the wind energy plants exceeds a limiting value of this wind energy plant, the desired value for this wind energy plant is limited to the limiting value of this wind energy plant. 6. The method according to claim 5, characterized in that the difference between the not limited desired value and the limiting value is distributed to one or plural remaining wind energy plants. 7. The method according to claim 1, characterized in that a characteristic curve is provided for each one of the wind energy plants, in which the maximum available value of the wind energy plant or of a group of wind energy plants is laid down depending on one or plural external variables. 8. The method according to claim 1, characterized in that the wind velocity and/or the wind direction is/are provided as the external variable. 9. The method according to claim 1, characterized in that the electric variable represents the active power and/or the active current of the wind energy plant. 10. The method according to claim 1, characterized in that the electric variable represents the reactive power and/or the reactive current. 11. The method according to claim 1, characterized in that the electric variable represents the phase angle and/or the power factor. 12. The method according to claim 1, characterized in that the electric variable represents the apparent power and/or the apparent current. 13. The method according to claim 1, characterized in that to at least one of the wind energy plants, a minimum available value is assigned, which is provided as the desired value when the desired value determined by the supervisory control is smaller than the minimum available value. 14. The method according to claim 13, characterized in that when the desired value for at least one wind energy plant is limited to the minimum available value, the desired value of at least one of the other wind energy plants is decreased. 15. 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, wherein the wind park has at least one supervisory control which stores a maximum permitted value for the electric variable provided by the wind park, the supervisory control determines a desired value for the electric variable for each wind energy plant and forward it to the wind energy plant, characterized in that the supervisory control determines each desired value for the wind energy plant depending on the currently maximum and/or minimum available values of the wind energy plants, and further wherein the supervisory control determining the desired value for a wind energy plant as a currently maximum available value of the wind park, divided by the number of the wind energy plants, weighted with a quotient of the currently maximum available value of the wind energy plant and the arithmetic mean of all the currently maximum available values of the wind energy plants. 16. The wind park according to claim 15, characterized in that the supervisory control determines each desired value of one of the wind energy plants depending on the currently maximum available value of the wind energy plant and the preset permitted value for the electric variable. 17. The wind park according to claim 15, characterized in that a characteristic curve is provided for each one of the wind energy plants, in which the maximum available value of the electric variable of the wind energy plant or of a group of wind energy plants is laid down depending on one or plural external variables. 18. The wind park according to claim 15, characterized in that the wind velocity and/or the wind direction is used as the external variable. 19. The wind park according to claim 15, characterized in that the electric variable represents the active power and/or the active current of the wind energy plant. 20. The wind park according to claim 15, characterized in that the electric variable represents the reactive power and/or the reactive current. 21. The wind park according to claim 15, characterized in that the electric variable represents the phase angle and/or the power factor. 22. The wind park according to claim 15, characterized in that the electric variable represents the apparent power and/or the apparent current. 23. The wind park according to claim 15, characterized in that to at least one of the wind energy plants, a minimum available value is assigned, which is provided as the desired value when the desired value determined by the supervisory control is smaller than the minimum available value. 24. The wind park according to claim 23, characterized in that when the desired value for at least one wind energy plant is limited to the minimum available value, the desired value of at least one of the other wind energy plants is decreased.
