Flexible interconnection device for power distribution network

The utility model discloses a flexible interconnection device for a power distribution network, which comprises a plurality of AC/DC bidirectional converters, DC ends of the AC/DC bidirectional converters are electrically connected, and AC ends of the AC/DC bidirectional converters are electrically connected with an input end; and a mechanical interconnection switch is arranged in front of two different groups of AC/DC bidirectional converters and is electrically connected with AC ends of the AC/DC bidirectional converters respectively. A flexible interconnection device formed by an AC/DC bidirectional converter and a mechanical interconnection switch is integrated on the basis of a traditional power distribution network interconnection switch. The power flow between the bus and the feeder line during the normal operation of the distribution network is realized, the power of the substation bus with lower load rate can be fully utilized, and the energy utilization rate is improved.
