Key technologies of smart distribution grid

Abstract

In order to build a strong smart grid with Chinese characteristics, the smart distribution grid issue is studied. Some present questions hindering the futuristic development of electric power distribution are proposed. The definition of smart distribution grid is given. The detailed characteristics are analysed in the paper, several functional requirements are put forward, and the development in the corresponding field is reviewed. The key technologies deployed for the realization of the smart distribution grid are explored in depth, which would give advice for the further research and implementation of distribution network intellectualization in the future. By incorporating with new technologies like Big Data and Internet of Things, SDG is prone to obtain a new opportunity to develop.
