Abstract
In order to improve the stability of power grid operation and prevent large scale power blackouts,identifying crucial branches in power systems accurately and quickly is of great significance.The theories of complex network and entropy are integrated to evaluate the branch importance from the overall perspectives of structure and running state.Firstly,the index of active power transmission betweenness considering the transmission margin rate is proposed to measure the branch transmission capability and its importance in the topological structure of the power grid.Then,the index of impact based on improved transfer entropy of power flow is proposed to evaluate the power flow impact on the power system caused by branch outages.Finally,an assessment index of synthetical importance of branches is set up to fully measure the importance of branches,including indices of active power transmission betweenness and impact.The test on an IEEE 39-bus system demonstrates the method proposed is valid and rational.关键词
