Abstract: It is described a method for controlling at least one considered wind turbine (5) in a wind park (1), comprising: determining, based on a wind condition (7b), in particular wind direction (7b), whether another wind turbine (9a, . . . ,9e) is in a wake region caused by the considered wind turbine; if another wind turbine (9b) is the closest wind turbine in the wake region (11b) and if the other wind turbine (9b) is in an operable state, applying a first control setting (15) to the considered wind turbine (5); if the other wind turbine (0b) is in a non-operable state applying a second control setting (17) to the considered wind turbine (5), wherein the first control setting is based on wind park level optimisation and the second control setting is based on wind turbine level optimisation.

Abstract: A system includes at least one processor and at least one module operable by the at least one processor to receive at least one sensor measurement. The at least one sensor measurement may include at least one of a wind speed measurement, or a wind direction measurement. The at least one module may be further operable to determine, using a stochastic filter, and based on the at least one sensor measurement, at least one predicted attribute of a wake generated by a wind turbine, the wind turbine being one of a plurality of wind turbines of a wind plant.
