In order to supply a load network 11 by means of an actuating element (for example an invertor 2 which is supplied from a solar generator 1) the magnitudes (/Un/, /Uw/) of the output voltage vector Uw and of the load-voltage vector U-n, and the angular difference or the frequency difference between the two vectors are formed by means of suitable measuring devices. An additional magnitude desired value Uz<*> and an additional phase desired value phi z<*> are in each case formed from input desired values for the real current /Iw/sin phi and the reactive component /Iw/cos phi as well as set parameters R and X for the resistance and the impedance of the coupling circuit, using the relationships /I/<*> = (/Iw/sin phi )<*> + R/X.(/Iw/cos phi )<*> and ( phi <*> = (/Iw/ phi cos phi )<*> - R/X.(/Iw/sin phi )<*>. The additional magnitude desired value is supplied together with the load-voltage magnitude as the desired value and the output-voltage magnitude as the actual value to a magnitude controller which is connected upstream of the amplitude-control input of the actuating element. If the actuating element also has a phase-control input in addition to a frequency-control input, the additional phase-control desired value is supplied to the phase-control input, and the output of a frequency regulator to which the frequency difference between the load voltage and the output voltage is applied is supplied to the frequency-control input. If only a single input is present for controlling the frequency and phase, a phase regulator is connected upstream of this input, to which the additional magnitude desired value I<*> [lacuna] as the desired value and the angle difference [lacuna] as the actual value ...
