摘要
A method for controlling an active power output in a wind farm comprises inputting a setpoint of the active power into a ramp and limiting unit to determine an internal active power setpoint. Inputting the internal active power setpoint into a distributing unit configured to calculate a modeled active power setpoint of the wind farm. Determine by a subtraction element, a control difference that is a difference between the modeled active power setpoint and an actual value of the active power output of the wind farm. Determine a controller setpoint variable and calculating an overall setpoint variable from the controller setpoint variable and the feed-forward control variable. Splitting the overall setpoint variable for models of the wind turbines and determining using the wind turbine models the modeled active power setpoint of respective wind turbines depending on a portion of the active power setpoint.
