Abstract: In order to respond to the different needs of distribution network users, flexible distribution switch（FDS）was introduced into the distribution network to achieve its flexible operation in this paper. On the basis of expounding the technology concept and connotation of FDS, this paper analyzed and explained the coordinate and control technology of distribution network based on multi-terminal FDS, such technologies include distributed generation consumption,power quality improvement, distribution network operation optimization and self-healing control technology etc. Finally,taking an example of a regional power grid in Guangdong to verify and analyze the effect of distribution network control technology based on multi-terminal FDS.
