摘　　要：针对现有配电网线路脆弱性评估指标单一的问题,从配电网结构、运行状态和故障影响等三个方面出发,全面考虑网络拓扑结构、负荷类型、潮流分布、设备参数和线路故障等影响因素,提出了改进的线路介数、改进的线路度数、线路电压稳定性和线路潮流熵等脆弱性评估指标。为解决权重分配过程中出现的权重偏好问题,提出基于博弈论与改进CRITIC-AHP组合赋权法的综合评价模型。最后,通过在IEEE33节点系统上进行仿真,验证了所提方法的有效性。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 parameters,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 CRITIC-AHP combination weighting method is proposed.Finally,simulation on an IEEE33 node system verifies the effectiveness of the proposed method.
