摘　　要：为建立合理的配电网经济运行评价指标体系,首先由专家建立初始主观评价指标体系,定义了确定指标、不确定指标和中心指标,利用改进模糊聚类方法对不确定指标进行分类,然后利用群灰色关联度法确定待筛选指标,并运用证据理论融合待筛选指标的专家可信度,最后依据可信度融合结果对待筛选指标进行闭环调整,消除冗余指标。算例结果验证了该评价指标体系的有效性。To establish a rational index system to evaluate economic operation of distribution network, firstly the initial subjective index system is built by expert and three indices, namely the certainty indices, the uncertainty indices and the center index, are defined. Utilizing the improved fuzzy clustering, the uncertainty indices are classified, then by use of group grey relational grade the indices to be screened are determined, and applying evidence theory the expert confidence of indices to be screened is fused; finally, according to fusion result of evidence the closed-loop adjustment of indices to be screened is performed to eliminate redudant indices. The effectiveness and practicability of the proposed index system are verified by calculation example.
