A FAST POWER SYSTEM NETWORK TOPOLOGY BASED ON TRACKING TECHNOLOGY

A fast tracking method for network topology based on breadth-first search is presented, which effectively surmount the defect of repeatedly searching the branch in traditional topology. In the presented method the power equipments are abstracted as nodes and branches, so for topology process the constraint from the connection scheme and the structure of the power network can be avoided and the topological analysis both for transmission network and distribution network can be carried out consistently. Moreover, using the adjacency list of node-branch in this method, the topology is accelerated. When the state of switches changes, only local network topology is necessary, so the flexibility of topology is improved. The presented method can meet the topological needs of networks in various voltage classes.
