Abstract
The present invention relates to a method for injecting electrical energy into an electrical, three-phase grid, comprising the steps of: injecting current by means of an injection unit at a grid connection point, detecting an asymmetry in the grid, in particular a negative sequence component in the grid, injecting an asymmetrical current portion into the grid for, at least, partial compensation of the detected asymmetry, with injection of the asymmetrical current portion taking place such that the injection unit behaves like a consumer.
