Smart distribution network contains multiple types of distributed generation and diversity of load. Optimal dispatch is an urgent need to achieve the optimal allocation of resources. In recent years

the construction of distribution automation systems and information systems provide the foundation for the optimal operation of distribution network. From smart distribution network actual needs

the optimal dispatch architecture is built in order to achieve globally optimized dispatch to the variety of intelligent distribution network elements. Based on two technologies

which include distribution network situational awareness and operation trend analysis

the overall optimal dispatch for distribution network is put forward. The technical framework and main functions of distribution network optimization and dispatch are given

including situational awareness

optimizations

content optimization and artificial decision. In order to achieve optimal dispatch for smart distribution network

six key technologies are need to be broken through.
