MVDC is an option for enhancing transfer capacity of lines (cable, overhead line) and providing improved power control at distribution networks. There are several advantages for network operation by converting existing medium voltage AC cable systems to DC operation. Different technical aspects need to be considered for refurbishing and also in case of application of standard MVAC cables for MVDC. The economic aspects of MVDC need to be compared to standard solutions. Investigations with respect to CIGRE TB 496 show that a 12/20 kV XLPE cable system for AC operation might pass the prequalification test for an extruded 55 kV MVDC cable.
