The invention relates to a method for feeding electrical power of at least one wind turbine (100) or of a wind farm (112) into an electrical supply network (120) having a network voltage (U) and a network frequency (f), wherein the method is prepared for feeding in active electrical power (P) and reactive electrical power (Q) and the fed-in active power (P) can be adjusted on the basis of at least one network state by means of an active-power controller and/or the fed-in reactive power (Q) can be adjusted on the basis of at least one network state by means of a reactive-power controller and the active-power controller and/or the reactive-power controller can be changed according to type and/or parameterisation.
