The situation awareness of smart distribution system is the critical foundation for the reliability
economy and safety of distribution system operation. The content
framework and key technologies of situation awareness and orientation for smart distribution systems are presented and discussed. First
the content and target of situation awareness and orientation are given. Next
the system framework of the technologies of situation awareness and orientation is constructed. Finally
in order to fully grasp the situation of distribution network operation and provide strong support for the smart dispatching of complicated distribution network
key technologies from five aspects of situation perception
situation comprehension
situation projection
situation visualization and situation orientation are summarized and prospected to provide a reference for further study. This work is supported by National Basic Research Program of China(973 Program)(No. 2013CB228203)and National Natural Science Foundation of China(No. 51377115).
