Identification of Vulnerable Line in Power Systems Based on Absolute Flow
摘要
Abstract
The identification results of vulnerable lines are decided by the operation topology of power grid.It is very difficult to recognize the vulnerable lines fast and accurately.On the basis of the influence of grid power flow,absolute power flow,the character of node and the constraint of lines,the generator-lines power distribution factors,absolute power factors and line weighted factors are calculated,and the index of weighted absolute flow coefficient is proposed to identify the vulnerable lines.The load shedding and global efficient function under continuous attacking are used to estimate the vulnerability of lines.Finally,the effectiveness of the algorithm is proved by IEEE-39 and IEEE-57 bus systems.The results show that the proposed algorithm can improve the accuracy and efficiency of identification and can be applied to guide the power system plan and dispatching.关键词
