Abstract: The disclosure relates to a method of operating a wind power plant, and related power plant controller and wind power plant. The method comprises determining a first active power at a first operating point and applying a first limit value for a reactive power limit. The method further comprises determining a second active power at a second operating point. The method further comprises, responsive to determining that the second active power meets one or more active power conditions referenced to the first active power, applying a second limit value for the reactive power limit. Applying the second limit value comprises limiting a ramp rate of the reactive power limit. The method further comprises generating control signals for one or more wind turbines to control a collective reactive power output of the wind power plant in accordance with the reactive power limit.

Abstract: Controlling a current injected to a power grid from a renewable power plant, in response to a voltage event in the power grid. At least a current at a point of common coupling between the renewable power plant and the power grid is determined and provided to a power plant controller (PPC). The PPC derives individual current setpoint corrections for at least some wind turbines, based on the determined current, and dispatches each derived current setpoint correction to wind turbine controllers of the corresponding wind turbines. The wind turbine controllers control a current output of the respective wind turbines, based on measurements of current and/or voltage at a point of connection between the wind turbine and an internal grid of the renewable power plant, and by taking into account the dispatched current setpoint correction.

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