摘　　要：为了评估分层储能系统用于含高渗透光伏发电区域配电网中的适用性问题,考虑其平抑光伏出力及为电网提供辅助服务等实际功能,提出考虑多利益主体的分层储能系统综合评估指标体系,基于层次分析法(AHP)和改进逼近理想解法(TOPSIS)提出了多模型综合评估算法。针对层次分析法中判断矩阵生成权重的主观性问题,引入变异系数法计算客观权重,并改进了逼近理想解排序法中的判定策略,提出基于距离接近度与夹角接近度的综合判断方法,进一步提高评估结果的精度。算例表明:所提出的指标体系具有较好的完备性,综合赋权方法可以提升、发掘优势指标,改进的综合评估算法可信度更高,对分层储能系统的推广应用有一定的实际意义。In order to evaluate the applicability of hierarchical storage system（HSS） used in regional distribution network with high permeability photovoltaic, the HSS index system for multi-interest subject is proposed considering its practical functions as smoothing photovoltaic output and providing ancillary service, and the comprehensive evaluation algorithm based on analytic hierarchy process（AHP） and technique for order preference by similarity to ideal solution（TOPSIS） is established. Furthermore, the variation coefficient method is adopted to solve subjective deviation problem of judgment matrix by calculating the objective weight, and the improved TOPSIS method considering distance approach degree and angle approach degree is used to increase the evaluation precision. Numerical results show that the HSS index system has preferable completeness feature, the synthetic weighting method can locate the important index, the results of improved comprehensive evaluation algorithm is more authentic and the work in this paper is meaningful for HSS application.
