基于最大离差与系数熵的配网规划评估方法

现有配电网规划评估方法中,缺少同时量化专家主观经验与指标客观因素的综合求解模型。分析了配电网规划参与者的利益诉求,搭建了一套较为完整的配电网规划综合评价指标体系。利用最大离差和最大系数熵的组合权重求解方法求解了指标权重值,该方法既考虑了专家对指标的先验知识,又兼顾了组合评价指标对方案的客观影响因素。采用实际配网的规划方案进行评估验证,结果证明了方法的工程实践意义,可以作为配电网络规划、扩建工作的参考评价方法。

Evaluation method of distribution gridplanning based on maximum deviation and coefficient entropy

The present evaluation index system of distribution network planning cannot quantify both subjective experiences of experts and objective factors. The benefit demands of participants are analyzed and a comprehensive evaluation index system is built. A combination weighting method based on maximum dispersion and maximum coefficient entropy is utilized to obtain the indices weight. The proposed method considers both the prior knowledge of the experts and objective influence factors of indicators. The actual distribution network planning scheme is used for evaluation and verification. The case study indicates the engineering practice of the method. The method provides a reference for the planning and expansion of the distribution network.
