Research Review on Smart Distribution Grid

Smart distribution grid(SDG) is the focus of the future smart grid construction, it will have a profound impact on the operation of power system protection and control. In this paper, the concept and characteristics of SDG are systematically introduced, then brief introduce SDG background, significance, as well as overseas and domestic research status. The key technologies of SDG are discussed, including the distribution network self-healing control(SHC), distribution fast simulation and modeling(DFSM), advanced distribution automation(ADA), advanced metering infrastructure(AMI), active distribution network (ADN), distributed generation(DG) and smart micro grid technology. Combined with the current situation of smart distribution grid, it points the development tendency of SDG.
