Abstract
A method for controlling at least one considered wind turbine in a wind park, including: determining, based on a wind condition, in particular wind direction, whether another wind turbine is in a wake region caused by the considered wind turbine; if another wind turbine is the closest wind turbine in the wake region and if the other wind turbine is in an operable state, applying a first control setting to the considered wind turbine; if the other wind turbine is in a non-operable state applying a second control setting to the considered wind turbine, wherein the first control setting is based on wind park level optimisation and the second control setting is based on wind turbine level optimisation is provided.

A method for controlling at least one considered wind turbine in a wind park, the method comprising:
- determining, based on a wind condition, whether another wind turbine is in a wake region caused by the at least one considered wind turbine;
- sending a first control signal to control an operation of the at least one considered wind turbine as a function of determining that if the other wind turbine is a closest wind turbine in the wake region, with respect to the at least one considered wind turbine, and the other wind turbine is in an operable state, wherein the first control signal includes a first control setting defining a set point of one or more control parameters;
- sending a second control signal to control the operation of the at least one considered wind turbine as a function of determining that the other wind turbine is the closest wind turbine and the other wind turbine is in a non-operable state, wherein the second control signal includes a second control setting defining a set point of the one or more control parameters;
- and
- wherein the first control setting is based on wind park level optimisation and the second control setting is based on wind turbine level optimisation.
An arrangement for controlling at least one considered wind turbine in a wind park, the arrangement configured:
- to determine, based on a wind condition, whether another wind turbine is in a wake region caused by the considered wind turbine;
- to send a first control signal to control an operation of the at least one considered wind turbine as a function of determining that the other wind turbine is a closest wind turbine in the wake region, with respect to the at least one considered wind turbine and that the other wind turbine is in an operable state, wherein the first control signal includes a first control setting defining a set point of one or more control parameters;
- to send a second control signal to control the operation of the at least one considered wind turbine as a function of determining that the other wind turbine is in a non-operable state, wherein the second control signal includes a second control setting defining a set point of the one or more control parameters;
- and
- wherein the first control setting is based on wind park level optimisation and the second control setting is based on wind turbine level optimisation.
