ARRANGEMENT HAVING A DC TRANSMISSION LINK OR DC TRANSMISSION GRID AND METHOD FOR THE OPERATION THEREOF

A method operates an arrangement having a DC transmission link or a DC transmission grid to which at least two converters each having an AC voltage side and a DC voltage side are connected. A grid stabilization device is connected to the AC voltage side of one of the converters, subsequently referred to as near converter. The grid stabilization device has for the purpose of grid stabilization an energy store for the buffer storage of energy and/or an energy consumer for the consumption of electrical energy, and the grid stabilization device is isolated on the grid side from at least one other of the at least two converters, subsequently referred to as a remote converter, by way of the near converter. The grid stabilization device is actuated by at least one control signal that is produced and transmitted to the grid stabilization device by the near or the remote converter.
