ABSTRACT=Intelligent distributed control and protection is a promising route towards flexible and safety operation of distribution network with widespread access of distributed energy resources (DERs). A fundamental premise of the distributed decision-making is that each smart terminal can identify the topological structure of the feeder and track its changes. This paper proposes a distributed topology recognition method. The smart terminal unit (STU) requires no pre-set topology information. It can identify comprehensive topological information only relying on the local measurement and the information exchange with neighboring STUs. The proposed method is fault-tolerant to measurement failures, and can dynamically track the changes of network topology. Test examples are presented to verify the effectiveness of the method.
