Avoiding an overload for transmission links within a power supply system

1. A method for avoiding overloading of at least one link section configured to transmit electrical power within a power supply system for at least one load, the method comprising the following steps:

determining a requested power value of electrical power of the at least one load;

determining a maximum available power value of electrical power for the at least one link section, wherein the maximum available power value is dependent on a maximum load that can be placed on the at least one link section due to a power transmission capacity of the at least one link section; and

releasing the at least one link section to the at least one load for a transmission of a released value corresponding to the requested power value if the requested power value is less than or equal to the maximum available power value.

2. The method according to claim 1 , which further comprises requesting the requested power value as electrical power or strength of current or quantity of current.

3. The method according to claim 1 , which further comprises configuring the requested power value as a power profile requesting power values being variable over time.

4. The method according to claim 1 , which further comprises determining the requested power value by using a regulating unit.

5. The method according to claim 4 , which further comprises authenticating the at least one load by using the regulating unit in order to determine the requested power value.

6. The method according to claim 1 , which further comprises providing at least two link sections for at least two loads.

7. The method according to claim 6 , which further comprises subtracting the at least one requested power value from a predefined power value of the link section in order to determine the maximum available power value per link section, wherein the predefined power value of the link section is the maximum possible load that can be placed on the at least one link section.

8. The method according to claim 1 , which further comprises preventing the release if the requested power value of the at least one load exceeds the maximum available power value.

9. The method according to claim 1 , which further comprises carrying out the release by issuing authorization being encoded as an authorization token.

10. The method according to claim 9 , wherein the token is a certificate.

11. The method according to claim 1 , which further comprises carrying out the release for a pre definable time period.

12. The method according to claim 1 , which further comprises determining a value of a drawn electrical power of the at least one load, and receiving a message at the at least one load if the value exceeds the value released for it.

13. The method according to claim 12 , which further comprises providing the message in the form of a disconnection of the at least one load from the power supply system.

14. A regulating unit for avoiding overloading of at least one link section configured to transmit electrical power within a power supply system for at least one load, the regulating unit comprising:

a first unit configured to determine a requested power value of electrical power of the at least one load;

a second unit configured to determine a maximum available power value of electrical power for the at least one link section, wherein the maximum available power value is dependent on a maximum load that can be placed on the at least one link section due to a power transmission capacity of the at least one link section; and

a third unit configured to release the at least one link section to the at least one load for a transmission of the requested power value if the requested power value does not exceed the maximum available power value.

15. The regulating unit according to claim 14 , which further comprises at least one fourth unit configured to:

determine the requested power value of electrical power of the at least one load;

determining the maximum available power value of electrical power for the at least one link section; or

release the at least one link section to the at least one load for a transmission of a released value corresponding to the requested power value if the requested power value is less than or equal to the maximum available power value.

16. The method according to claim 1 , wherein the maximum available power value is the maximum possible load on lines for transmitting power.
