The invention relates to a wind farm comprising at least two wind turbines (1) and a farm master (2) having a power controller (3) for controlling the wind turbines (1), to which farm master a target-value signal for the wind farm power output (Ps_Park) is applied and which farm master outputs target signals for the power output of the wind turbines (Ps_WEA), wherein the power control (3) has a predictor (4), which is designed to determine corrected target values for the wind turbines (1) in the event of a change in the target-value signal for the wind farm, wherein the corrected target values are output to the power controller (3). Thanks to the predictor (4), the target value for the wind turbine can be calculated more quickly and more accurately after target-value jumps for the wind farm. This also applies in particular if the wind turbines are in different operating states and produce different amounts of power.
