With the sustained development of smart grid, a variety of innovative power distribution and utilization business appear in an endless stream, existing power distribution and utilization communications network infrastructure are not well equipped to meet the flexibility, openness requirements of future power business. In this paper, the communication needs of emerging new smart power distribution and utilization business in power communication network are analyzed. A power distribution and utilization communication network scheme which based on SDN technology, combined with network virtualization and integration of fusion gateway technology is given, the basic architecture of the network and key technologies is studied. Finally, the expand application of SDN technology in the power distribution and utilization business is prospected.
