A method for controlling electrical network variables ( N x,k ) at a network connection point at an output of a feed network which, at an input of the feed network , is connected to at least one power converter at a power converter connection point , wherein at the power converter connection point at least one feed variable ( E x,k ) and at the network connection point at least one network variable ( N x,k ) are measured, characterized in that the correlation between the at least one feed variable ( E x,k ) and the at least one network variable ( N x,k ) is described in a model-like manner by means of a model of the feed network , wherein the model of the feed network is implemented in a control unit of the feed network , in that - in the event of a deviation of the measured at least one network variable ( N x,k ) from a network variable ( Ñ x,k ) to be expected based on the model of the feed network and/or a deviation of the measured at least one feed variable ( E x,k ) from a feed variable ( E x,k ) to be expected based on the model of the feed network an erroneous description of the correlation is detected by the control unit , and an adaptation of the model of the feed network is carried out by the control unit in order to correct the erroneous description of the correlation by the model of the feed network , wherein at least a portion of the detected measurement data of the at least one feed variable ( E x,k ) and at least a portion of the detected measurement data of the at least one network variable ( N x,k ), are used, - in that the control unit determines, by means of the model of the feed network from a predefined network variable target value ( N x,k *) for the at least one network variable ( N x,k ) a feed variable target value ( E x,k *) for the at least one feed variable ( E x,k ), - and in that the at least one feed variable ( E x,k ) is set using the at least one power converter to the determined feed variable target value ( E x,k *). - in the event of a deviation of the measured at least one network variable ( N x,k ) from a network variable ( Ñ x,k ) to be expected based on the model of the feed network and/or a deviation of the measured at least one feed variable ( E x,k ) from a feed variable ( E x,k ) to be expected based on the model of the feed network an erroneous description of the correlation is detected by the control unit , and an adaptation of the model of the feed network is carried out by the control unit in order to correct the erroneous description of the correlation by the model of the feed network , wherein at least a portion of the detected measurement data of the at least one feed variable ( E x,k ) and at least a portion of the detected measurement data of the at least one network variable ( N x,k ), are used, - in that the control unit determines, by means of the model of the feed network from a predefined network variable target value ( N x,k *) for the at least one network variable ( N x,k ) a feed variable target value ( E x,k *) for the at least one feed variable ( E x,k ), - and in that the at least one feed variable ( E x,k ) is set using the at least one power converter to the determined feed variable target value ( E x,k *). <EOS>
