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 first renewable energy power plant by determining power delivery of the first renewable energy power plant to a collector bus; receiving data relating to power delivery from a second renewable energy power plant connected to the collector bus; determining the combined power delivery of the first and second renewable energy power plants to the collector bus; estimating the transmission line power loss on a first transmission line between the collector bus and a power grid point of interconnection (POI) based on the combined power delivery; and regulating the power delivery from the first renewable energy power plant to compensate for the estimated transmission line power loss.

Abstract: Aspects of the present invention relate to a method for controlling active power output of a renewable energy power plant comprising one or more renewable energy generators. Aspects of the invention may be used to control the active power output of a wind energy power plant and to determine accurate estimates of the available active power when the frequency level of the connected power network is outside of the frequency deadband.

Abstract: Aspects of the present invention relate to methods for controlling active power output of a wind turbine generator in response to a frequency event on a power network to which the wind turbine generator is connected, wherein the active power output of the wind turbine generator is limited to be below an upper active power limit and/or above a lower active power limit. The methods comprise determining and dispatching active power references to a controller of the wind turbine generator for controlling the wind turbine generator. The methods operate to ensure that the value of the active power reference immediately after the frequency event is within the allowable active power range, thereby avoiding any mismatch between the reference and the output that may cause a delay in returning to normal operation.

Abstract: The invention relates to a power plant controller for controlling wind turbine generators. More particularly, the invention relates to a method for compensating data obtained from measurements at a connection point to the grid in case of a communication failure where communication of such data is lost or becomes unreliable. The measured data are used in the power plant controller for determining setpoints for controlling the wind turbine generators' production of active and reactive power. In response to detection of a communication fault a new setpoint is determined independently of new measured grid data by reconfiguring parts of the power plant controller.
