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) and the controller manipulated variable.
