Abstract

In order to coordinate power generators and consumers in a power grid using intelligent management, a method for generating power is provided wherein at least two decentralized power generators are connected to an electric power grid. A value for the current output of at least one power generator is measured and compared to a nominal output. The output of the power generators connected to the electric power grid is adapted according to the result of the comparison.

Claims

1. A method for producing power with at least two decentralized power converters connected with a global power network, comprising the steps of:

determining power-generator-specific parameters of at least one of the power converters;

transmitting the determined power-converter-specific parameters to the global data network via a standardized interface, said standardized interface merging the determined power-converter-specific parameters;

processing the merged power-converter-specific parameters with a central data server provided in the global data network into an actual command for at least one of the power converters;

transmitting the actual command via the standardized interface from the global data network to the at least one power converter; and

adjusting operating parameters of the at least one power converter based on the actual command.

2. A device for producing power, comprising

at least two power converters connected with a global power grid, and

at least one standardized interface connecting at least one of the power converters with a global data network.

3. The device of claim 2, wherein the global data network includes a central data server

4. The device of claim 2, wherein at least one of the power converters is a power generator, the device further comprising means for forecasting the power to be produced by the at least one power generator, said means selected from the group consisting of wind measuring devices, weather stations, and exposure meters.

5. The device of claim 2, and further comprising a data receiving station and means for automatically integrating the data receiving station into one of the global power grind and the global data network.

6. The device of claim 2, and further comprising an output unit for outputting information about the state of at least a power converter and the power grid, said output unit including means for checking an authorization of a reader of the output unit for receiving the information.

7. An interface of a global data network, comprising:

connections to at least two power converters connected with a global power grid; and

means for standardizing power-converter-specific parameters of the at least two power converters.

8. A profile of an interface, wherein the profile standardizes parameters specific to at least one of power-converter-specific parameters and power grid specific parameters.

9. The profile of claim 8, wherein the profile filters the power-converter-specific parameters into business-specific data and multimedia-specific data and provides the data to different clients.

10. A power generator, comprising an automatically readable interface to a global or national network for indicating an actual power output of the power generator.

11. The power generator of claim 10, wherein the automatically readable interface further comprises an output unit that outputs a power that can be produced by the power generator.

12. The power generator of claim 11, wherein the output unit indicates information about an actual state of the power generator.

13. The power generator of claim 11, further comprising an input unit for an automatic control of the power.

14. The power generator of claim 11, wherein the output unit provides information indicating a state of the power generator, said output unit including means for checking an authorization of a reader for reading the information provided by the output unit.

15. A method for acquiring data of power generating plants, in particular wind power plants, wherein the acquired data are automatically transmitted from the power generating plants to at least one data server via a local network (LAN).

16. The method of claim 15, wherein the data server is connected to a wide area network (WAN) and transmits information automatically to the at least one central data server via the WAN.
