Abstract: A method for controlling a renewable energy generator, the renewable energy generator being connected to a Point of Interconnection of an external power grid by a connecting network, wherein the connecting network has an associated impedance level. The method comprising: monitoring at least one parameter of the connecting network and the voltage level at the Point of Interconnection; generating, during normal operating conditions, at least one current injection profile based upon the at least one measured parameter and a predetermined injection profile; and operating the renewable energy generator, during a grid fault, to output current according to the at least one current injection profile, so as to achieve a current set point at the Point of Interconnection.

Abstract: A method of operating a wind turbine above a predefined wind velocity comprising the step of operating a control parameter of the wind turbine within a tolerance band from a reference set-point curve of that control parameter. A wind turbine and a cluster of wind turbines is also contemplated.

Abstract: A method of operating a wind turbine with pitch control, in which values of the generated power and the operating speed of the rotor are established at a discrete number of secure ranges for wind speeds above a critical wind velocity. A wind turbine and a cluster of wind turbines employing such a method are also contemplated.

Abstract: A method of operating a pitch controlled wind turbine connected to the utility grid in response to an increase in wind velocity to above a predefined value. The method includes the sequential steps of: reducing the generated power, allowing an intermediate increase in the generator speed, and reducing the generator speed by pitching the wind turbine rotor blades. A wind turbine and a cluster of wind turbines is also contemplated.
