Publication number: 20240035443Abstract: 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.Type: ApplicationFiled: December 6, 2021Publication date: February 1, 2024Inventors: Rubin PANNI, Kouroush NAYEBI, Jesurathinam Arockia ARUN PRASAD

Publication number: 20240014663Abstract: The invention relates to a method for controlling a power plant during an event which requires a change of the power produced by the power plant, wherein the power plant comprises a plurality of power generating units including at least one wind turbine generator, the method comprises determining the power reference dependent on an available power, changing the power reference to a modified power reference by a power variation in response to detecting a first event, memorizing a power level relating to the actual power production at a time occurrence of the first event, setting a maximum power limit to the memorized power level, limiting the modified power reference to the maximum power limit, and controlling the power produced by the wind turbines in accordance with the limited modified power reference.Type: ApplicationFiled: October 19, 2021Publication date: January 11, 2024Inventors: Dan WU, Rubin PANNI, Henrik MØLLER

Publication number: 20230407841Abstract: 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.Type: ApplicationFiled: October 25, 2021Publication date: December 21, 2023Inventors: Dan WU, Rubin PANNI, Kouroush NAYEBI

Patent number: 11401917Abstract: 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.Type: GrantFiled: December 20, 2019Date of Patent: August 2, 2022Assignee: VESTAS WIND SYSTEMS A/SInventors: Jorge Martinez Garcia, Rasmus Lærke, Henrik Møller, Kouroush Nayebi, Rubin Panni, Chun Meng Heng
