Abstract
Considering propagation characteristics of load and batch power source fluctuation in network,this paper presents a method for key branch identification based on comprehensive betweenness which is used to fully reflect weak links of the system in particular operational environment or with specific network structure and running model. Then it proposes a power grid partitioning method based on node electrical distance clustering and its modification measures so as to avoid missing im-portant lines. Finally,on the basis of grid partitioning and according to features of power transmission section,it selects key branch leading power transmission section as the key section of system. IEEE 39 node system example is used to verify effec-tiveness of this method. It is able to search for the key power transmission section according to load or batch energy fluctua-tion characteristic and system running mode at any time in actual application,so as to provide basis for adopting security con-trol measures for the system.关键词
