A method for determining a limit value of a wind turbine reference operational variable is described The wind turbine being connected to a connection node to which a utility grid is connected. The method includes: obtaining a first input signal indicative of a connection node limit voltage; obtaining a second input signal indicative of a connection node voltage; and determining the limit value of the wind turbine reference operational variable based on the first signal and the second signal. Further a corresponding arrangement is described.

Method and arrangement for operating a wind farm within voltage limit

A method is provided for determining a voltage bounding range defining a range of a wind turbine reference voltage for a wind turbine for controlling an output voltage of the wind turbine at a wind turbine output terminal. The method includes obtaining information regarding an electrical characteristic of a transmission line connecting the wind turbine output terminal to a point of common coupling to which plural other wind turbines are connectable. The method further includes defining the voltage bounding range based on the electrical characteristic of the transmission line.
