Claim 0:
1. A method for operating a wind turbine or a plurality of wind turbines combined in a wind farm with a control unit connected to a remote-access data transmission network to control a power feed-in of the wind turbine or the plurality of wind turbines combined in the wind farm, wherein the control unit receives control signals from at least two higher-level controls with different priorities, checks from which higher-level control a control signal originates, and implements or discards the control signal, the method having the following steps executed in the control unit:
receiving a control signal from one of the at least two higher-level controls;
checking to identify the higher-level control of the at least two higher-level controls from which the control signal originates;
if the control unit is reserved for the higher-level control of the at least two higher-level controls from which the control signal originates: implementing the control signal;
if the control unit is reserved for a different higher-level control of the at least two higher level controls: checking whether the higher level control of the at least two higher-level controls from which the control signal originates has a higher priority than a priority of the different higher-level control for which the control unit is reserved:
if so: implementing the control signal received from the higher-priority higher-level control even though the control device is reserved for the different higher-level control;
if not: discarding the control signal.
