Research status and development prospect of smart distribution grid

Smart distribution grid is the focus of the future smart grid construction,it will have a profound impact on the operation of power system protection and control. Distribution grid after intelligent will not only have a variety of intelligent electrical equipments,but also allows a wide range of DG and microgrid access,thus further boosting supply and distribution of intelligent requirements on power grid. This paper introduced the main research focus on the process of intelligent distribution network development in recent years,with the ultimate goal of self-healing,expounds the aspects of distributed and renewable energy access,power supply and demand side management,self-healing control,also pointed out that the intelligent distribution network has not been resolved and the next possible research directions.
