摘要： A method for operating a renewable energy power plant comprising a plurality of renewable energy generators. The method comprises: identifying a predetermined condition of the renewable energy power plant, of the grid, or of the connection between the renewable energy power plant and the grid, the predetermined condition indicating a weak grid interconnection between the renewable energy power plant and the grid; and controlling each renewable energy generator in an adaptive active power mode in response to recovery of the grid from a voltage deviation. The adaptive active power mode comprises: determining a thermal capacity of a chopper resistor of the renewable energy generator; calculating, based upon the determined thermal capacity, a limit level of rate of change of active power output that may be implemented by the renewable energy generator; and operating the renewable energy generator to output active power at the calculated rate of change limit level.

摘要： A wind power plant has a plurality of wind turbine generators and a power plant controller arranged to communicate with the plurality of wind turbines generators. Each wind turbine generator has a controller arranged to control an active power output in its respective wind turbine generator according to an active power set point received from the wind power plant controller. A change in the active power reference changes the active power set point for each wind turbine generator by a weighting factor.

摘要： Aspects of the present invention relate to a method for controlling one or more wind turbine generators. The method comprises: monitoring an electrical parameter of a power network to which the wind turbine generators are connected with respect to a deadband for the electrical parameter; and determining that the monitored electrical parameter is deviating outside of the deadband. In response to determining that the electrical parameter is deviating outside of the deadband, the method comprises: quantifying a severity of the deviation; and selectively implementing a parameter control mode when the quantified severity of the deviation is at or above a threshold level. In the parameter control mode, one or more power set points are determined based on the value of the electrical parameter and are dispatched to control the wind turbine generators.

摘要： A method and control arrangement are disclosed for controlling power output of a wind power plant (WPP) including a plurality of wind turbine generators (WTGs). The method includes determining that overboosting is required for the WPP to meet a power demand at the WPP, and determining, for at least a first WTG of the plurality of WTGs, a corresponding amount of overboost capacity. The method further includes generating, based on the determined amount of overboost capacity, control signals causing the first WTG to increase its power output through overboosting to thereby fulfill at least a portion of the power demand.
