    Abstract: Method of operating a wind turbine comprising a plurality of blades rotatable along their longitudinal axes using a pitch mechanism, and comprising one or more movable trailing edge surfaces. The method includes predicting, at a first moment in time, a high load for one or more of the blades at a second moment in time. The method further comprises actuating on one or more of the movable trailing edge surfaces of these blades such that the trailing edge surfaces have a wider range of control to counteract the predicted high loads before the second moment in time, and simultaneously pitching the blades such as not to negatively affect the operation of the wind turbine. The method furthermore comprises, at the second moment in time, actuating the one or more movable trailing edge surfaces of the at least one or more blades to counteract the high loads.

    Abstract: Floating TLP wind turbine comprising a buoyancy structure, a plurality of braces, one or more tensioned mooring lines for each brace, and a support structure arranged on the buoyancy structure. The braces extend radially outwardly from a region of the buoyancy structure or support structure, each brace having a distal end portion with respect to the buoyancy structure or support structure. Each distal end portion of the braces comprises a guiding element to allow a guided passage of a tensioned mooring line. Each of the tensioned mooring lines is anchored to the seabed at a first end, and attached/coupled to a region of the buoyancy structure or support structure at a second end, said region being above the region of the buoyancy structure or support structure from which the braces extend radially outwardly. Each tensioned mooring line is guided by the guiding element of the corresponding brace.

    Abstract: Methods are provided of operating first and second wind turbines in a situation wherein presence of the first wind turbine affects the wind so that a wake is generated that affects the second wind turbine. These methods include determining parameters of the wind at first wind turbine and at second wind turbine. These methods further include determining a value of a parameter of a previously determined wake model to determine a current wake model. This value is determined based on the parameters of the wind at first wind turbine and at second wind turbine. These methods still further include optimizing the operation of the first and second wind turbines based on the current wake model. Control systems are also provided which are suitable for performing any of the methods of operating wind turbines. Wind farms are also provided including any of the control systems.
