Abstract
In order to control a plurality of inverters, which are connected on their input side to a current source each and on their output side to a common grid connection point, electrical variables are measured at the individual inverters and are used for controlling the individual inverters, currents being output by the individual inverters depending on the electrical variables measured at the location of the individual inverters Effects of the connection equipment between the individual inverters and the common grid connection point on currents are determined, electrical variables being measured at the grid connection point and are set in relation to the electrical variables measured at the same time at the individual inverters. The connection equipment between the individual inverters and the common grid connection point is taken into consideration in controlling the individual inverters.
