Abstract:
A method for controlling an active power in a wind farm comprises inputting an active power setpoint value into the wind farm model. Splitting the active power setpoint value of the wind farm among models of the wind turbines. Determining a modeled active power setpoint value of the wind farm as a sum of modeled active power setpoint values of the wind farm model. Determining a system deviation as a difference between the modeled active power setpoint value and an actual value of the active power output of the wind farm. Inputting the system deviation into a power controller which outputs a controller manipulated variable. Determining a feedforward controller manipulated variable independently of operating states of the wind turbines of the wind farm or the active power. Determining an overall manipulated variable as the sum of the freeforward controller manipulated variable (u ff ) and the controller manipulated variable.

Claim (Index 6):
A wind farm control system for a wind farm having at least two wind turbines and a setpoint value for the active power (P set , P set,global ) for controlling the at least two wind turbines that is configured to be output by the wind farm and input into the wind farm control system, the wind farm control system comprising:\n a feedforward control unit configured to determine a feedforward control manipulated variable (u ff ) independently of operating states of the at least two wind turbines of the wind farm and an actual value of the active power (P act ); a wind farm model configured to output a modeled active power value (P\u2032 set ) of the wind farm from the setpoint value for the active power (P set , P set,global ); a subtraction element configured to determine a system deviation (e) from a difference between the modeled active power value (P\u2032 set ) of the wind farm and the actual value of the active power (P act ) output by the wind farm; a power controller configured to determine a controller manipulated variable (u reg ) based on the system deviation (e); and a summation element configured to determine an overall manipulated variable (u) as the active power setpoint value for the wind farm from a sum of the feedforward control manipulated variable (u ff ) and the controller manipulated variable (u reg ), wherein the wind farm model comprises models of each of the at least two wind turbines, and wherein a portion (p siml ) of the actual value of the active power (P act ) to be output by the wind farm is input into each model of the at least two wind turbines, and wherein each model of the at least two wind turbines is configured to determine a modeled active power setpoint value of the active power (p simO ) to be output by an individual wind turbine.
