Abstract
Transmission sections have great significance in modern power systems. Given the phenomenon of frequent power outages caused by the chain tripping of transmission sections, a method for transmission section search based on the variable-scale affinity propagation clustering algorithm is proposed. Considering only the connection relationship, the power system model can be simplified to a topological map in graph theory for analysis. So firstly the algorithm considers the importance of each line from the perspectives of the structure of the graph and the actual operation of the power flow and then uses the variable-scale affinity propagation clustering algorithm for the network based on this value with the change of the number of cluster centers. The network will be partitioned at different scales, then find out the partition contact line at different scales, and judge whether it is a transmission cross-section by the power flow direction and the number of contact lines. This method can search out as many potential transmission sections of the power network as possible to provide more monitored objects for the staff and reduce the probability of large power outages. Finally, simulation in the IEEE-118-bus system and the IEEE-39-bus system verifies the effectiveness of the proposed method.
