摘　　要：为科学合理地评估电网运行安全能力,本文采用等级相关主观赋权法和指标信息量集成客观权重的综合赋权法,综合确定电网运行安全能力评价指标体系最终权重。构建了含有分辨系数的改进灰色关联综合评价模型,对某电网运行6个时期的安全能力进行评价,并与传统的灰色绝对关联度模型进行了对比。对比结果验证了本文模型的有效性和实用性。In order to scientifically and reasonably evaluate the power grid operation safety capability,this paper first adopts a comprehensive weighting method of the rank-related subjective weighting method and the index information amount to integrate objective weights for comprehensively determining the final weight of the grid operation safety capability evaluation index system.Then,an improved gray correlation comprehensive evaluation model with resolution coefficient is constructed.Finally,the safety capability of a power grid operation in six periods is evaluated,and compared with the traditional gray absolute correlation model.Results verify the validity and practicability of the proposed model.
