考虑多时间尺度的连锁故障演化和风险评估模型
Multi-timescale Cascading Failure Evolution and Risk Assessment Model
摘要
Abstract
The dynamic process of the cascading failure is ignored in its existing evolution models,which fails to fully consider the different time characteristics of the phenomena and the countermeasures in cascading failures.In this background,firstly a cascading failure model based on multi-timescales was proposed in the paper.According to the different time characteristics of the phenomena and the countermeasures in cascading failures,the proposed model divided the cascading failure into three separate processes with different time scales.The corresponding simulation models of the processes were established based on the time range and characteristics of each time scale.The three layer calculation structure was adopted to deal with the relationship between the three processes with different time scales.Then the cascading failure model was established.Secondly,the risk assessment of the obtained cascading failure path and its fault links was conducted based on the risk theory.Finally the IEEE 39 system was chosen as an example for simulation and analysis.The evolution characteristics and risk changes of the cascading failure as well as the influence of countermeasures on risk during the cascading failure were analyzed.关键词
