Research on technical framework of smart distribution network

The future development trend of electric power grid is smart grid, which include such features as flexible, clean, secure, economic, and friendly and so on. Smart grid involves power generation, transmission, transformation, distribution, consumption and dispatching. Distribution network locates at the end of power system, and due to its direct connection with consumers, the quality and ability of power supply is guaranteed by it. In this paper, the connotation, characteristics and the development goals of smart distribution network in China are expounded firstly. Secondly, the technical framework of smart distribution network, which include network infrastructure, information communication system and intelligent application system, is put forward. The main technical compositions of the framework are briefly discussed in succession. Lastly, the suggestion on development path of smart distribution network in china is proposed, in the hope of providing reference to the further research and implementation of smart distribution network.
