Distribution Line Vulnerability Assessment Based on Game Theory and Improved CRITIC-AHP
In response to the problem of single vulnerability assessment indicators for existing distribution network lines,starting from three aspects of distribution network structure,operating status,and fault impact,comprehensive consideration is given to factors such as network topology structure,load type,power flow distribution,equipment pa-rameters,and line faults.The vulnerability assessment indicators are proposed,such as improved line dielectric constant,improved line degree,line voltage stability,and line flow entropy.In addition,to address the weight preference issue that arises during the weight allocation process,a comprehensive evaluation model based on game theory and improved CRIT-IC-AHP combination weighting method is proposed.Finally,simulation on an IEEE33 node system verifies the effective-ness of the proposed method.
