    摘要:

    首先,对电网应急能力进行基于时间维度和空间维度的拆解,构建基本电网应急能力评价指标体系;其次,考虑到指标评价标准具有动态性的问题,采用三角模糊数对指标进行量化处理,并建立可对多个模糊数集结的优化模型;然后,采用α-截集对三角模糊数进行处理并建立基于单一时间节点下的模糊-两阶段超效率SBM模型实现对电网应急能力的静态评价;最后,以时间维度拆解为基础,建立电网应急能力动态综合评价模型,实现对应急能力的整体评价、排序,使评价结果更加具有科学性和合理性.实例分析结果表明,所提出方法可有效区分应急能力仍需作出改善的区域,并在一定程度上克服评价标准需要动态变化的问题,具有较强的客观性.

    Abstract:

    Firstly, the power grid emergency capability is disassembled based on time dimension and space dimension, and the basic power grid emergency capability evaluation index system is constructed. Secondly, considering the dynamic problem of the index evaluation standard, the index is quantified with triangular fuzzy numbers, and the optimization model for the aggregation of multiple fuzzy numbers is established. Then, the triangular fuzzy numbers are processed using the cut-off set, and the fuzzy two-stage super efficiency SBM model based on a single time node is established to realize the static evaluation of power grid emergency capability. Finally, the dynamic comprehensive evaluation model of power grid emergency capability is established based on the disassembly of time dimension, which realizes the overall evaluation and sequencing of corresponding emergency capability, making the evaluation results more scientific and reasonable. The results of case study show that the method can effectively distinguish the areas where the emergency capability still needs to be improved, and to a certain extent, it overcomes the problem of that the evaluation criteria need to change dynamically, and has strong objectivity.
