Critical Line Identification of Complex Power System in Cascading Failure
摘要
Abstract
There exist a small number of critical lines in power system that play key roles in the process of the power system large-scale cascading failure, therefore, in order to implement control strategy effectively in overload cascading trips and to prevent large-scale blackout, it is significant to identify critical lines in the power system rapidly, especially when the system is in a cascading failure state. According to the characteristic that blackouts usually associate with the large-scale active power flow transferring, the flow transferring index was proposed as vulnerability index. Based on the idea of steady-state security region analysis of the power system, a critical lines assessment model was established and an algorithm was given to identify the critical lines in the process of cascading failure. According to the IEEE 30 standard example system, this paper constructed a simulation process of a cascading failure by using the OPA blackout model, and validated the correctness of the proposed identification method through simulation.关键词
