Abstract
An arrangement for connecting first and second electrical supply systems includes a medium-voltage DC line, a first converter connected on the AC-voltage side to the first supply system and on the DC-voltage side to the DC line, a second converter connected on the AC-voltage side to the second supply system and on the DC-voltage side to the DC line, and a control device controlling electrical power transmission in the DC line by using at least one converter for transmitting a temporary excess of energy in the first supply system to the second supply system. A method for operating an electrical supply system includes making a temporary excess of energy in the supply system available to a further supply system connected to a medium-voltage DC line by using the line to which the supply system is connected by a converter, for stabilizing the supply system.
