Abstract

The present invention relates to a bipole power exchange arrangement (20) designed to exchange power between a power source and a DC network, comprising a first converter (21) arranged between a positive DC pole and a neutral DC pole, a second converter (25) arranged between the neutral DC pole and a negative DC pole, and a converter control (26, 27) providing a first converter voltage reference (Ucvr1) for the first converter and a second converter voltage reference (Ucvr2) for the second converter. According to the invention the converter voltage references each comprise at least two additive components, wherein one of the components is a residual voltage reference (Uresref) calculated using a droop control function based on a neutral pole current. The present invention further relates to a method for operating such arrangement.
