Abstract: The method allows stabilizing the rotation speed of a hydraulic machine with S-characteristics. It is implemented by means of a control loop feedback system having a controller for calculating an orientation to affect guide vanes of the machine. It includes steps of calculating a set of internal states associated with the operating point of the machine, establishing a linearized transfer function in function of the set of internal states, calculating characteristics parameters of the controller in function of the established transfer function so that the control loop feedback system is stable, measuring the rotation speed of the hydraulic machine, comparing the measured rotation speed with a target rotation speed, and adjusting the orientation affected to the guide vanes so as to reduce the speed difference between the calculated rotation speed and the target rotation speed.

Abstract: Methods of operating a set of wind turbines for providing a total power demand to a grid according to a grid requirement are provided. A first group of wind turbines is configured to generate an individual active power based on an individual set-point. First individual set-points are generated for the first group such that the set of wind turbines generates the total active power. If a selection of the first group of wind turbines is operating within an individual exclusion range, the operation of the se wind turbines is limited to a maximum period. When the maximum period is reached, second individual set-points are generated to cause these wind turbines to operate outside exclusion range, and third individual set-points are generated for one or more other wind turbines to cause the set of wind turbines to generate the total active power. Systems suitable for such methods are also provided.
