Analysis on Cascading Failure Behavior for Weighted Power Grid
摘要/Abstract
根据实际IEEE118节点系统建立了加权电网的物理模型，考虑网络的电气特征，提出了基于负载容量模式下的级联失效动力学模型，同时理论推导容忍参数和系统调整系数之间的关系，并借助数值仿真验证了理论结果,进而研究了不同攻击方式对电网动力学弹性的影响.研究结果表明，不同攻击策略下加权电网的容量参数取值相差较大.
Based on the actual IEEE118-bus system a physical model of a weighted power grid was constructed.It is found that the weighted grid is more in line with the small-world characteristics of the taking into account the electrical characteristics of the network，non-linear load capacity model is introduced,the relationship between threshold value and parameters is theoretically derived,and the analysis results are verified by simulation.Furthermore,comparing different attack strategies,it is found that the weighted grid under different attacks requires a threshold value of capacity parameter.
