Abstract: Aspects of the present invention relate to a method (100) for controlling a renewable energy generator (14). The method (100) comprises: receiving (102) a signal from a power plant controller (22) indicating a reactive power setpoint; determining (104) reactive power limits for the generator (14); generating (106) a control signal for the renewable energy generator (14), the control signal being based on the reactive power setpoint and limited based on the determined reactive power limits; and controlling (108) the generator (14) according to the control signal. Determining (104) the reactive power limits comprises: determining (110) a generator limit corresponding to the reactive power capability of the generator (14); determining (112) a terminal voltage of the generator (14); comparing (114) the determined terminal voltage to a voltage limit: determining (116) a voltage-based limit based on the comparison.

Abstract: The invention relates to wind turbines, particularly to controlling reactive power exchange between a power grid and a wind power plant. The wind power plant has a plurality of wind turbine generators each having a corresponding power converter with a converter controller. Further, the wind power plant has a power plant transformer with an on load tap changer coupled between the wind power plant and the power grid. The power plant controller is regulating the on load tap changer and is generating reactive component setpoints for the wind turbine generators, when determining a need for production of short-term reactive power due to a sudden change in reactive power measured at the point of common coupling.

Abstract: Aspects of the present invention relate to a method (100) for controlling a plurality of renewable energy generators (14). The method (100) comprises: determining (102) preliminary reactive power set points for the generators (14) based on a reactive power reference value; determining (104) generator-based and voltage-based reactive power limits for the generators (14); generating (106) dispatch signals for requesting reactive power from the generators based on the preliminary set point and the limits; and dispatching (108) the dispatch signals to the generators (14). The generator-based reactive power limits correspond to the reactive power capability of the generator. The voltage-based limits are determined by: determining (112) a terminal voltage of the generator; comparing (114) the determined terminal voltage to a voltage limit; and determining (116) the voltage-based reactive power limit based on the comparison.
