摘　　要：随着我国配电网智能化的发展,边缘计算成为解决新形式下智能配电网云端冲突的有效模式,针对边缘计算模式中海量异构配用电数据造成的存储混乱与融合计算性能不足的问题,提出一种基于边缘计算的智能配电网多源数据处理与融合技术。首先,设计基于边缘计算的智能配电网多源数据处理与融合架构;其次,在原有Zscore数据标准化处理基础上引入Box-Cox转换,提出基于广义幂变换Zscore的多源数据处理方法,实现各配网数据源量纲和数量级的统一变换;然后,定义成分可信度函数约束DS推理过程中不确定特征属性融合,构建基于冲突优化DS推理的多源数据融合模型,实现对多源异构数据进行分组聚合;最后,在某城市配电网仿真环境进行实验分析,验证了该技术的有效性。With the development of smart distribution grid,edge computing has become an effective model for solving cloud conflicts in smart distribution grid under new forms.Aiming at the problems of storage confusion and insufficient fusion computing performance caused by massive heterogeneous distribution data in edge computing mode,a multi-source data processing and fusion technology for smart distribution grid based on edge computing was proposed.Firstly,the multi-source data processing and fusion architecture of smart distribution grid were designed based on edge computing.Secondly,the Box-Cox conversion was introduced on the basis of the original Zscore data standardization processing,and a multi-source data processing method based on the generalized power transformation Zscore was proposed to achieve a unified transformation of the dimension and order of magnitude of each distribution network data source.Then,the component credibility function to constrain the fusion of uncertain feature attributes in the DS inference process was defined,a multi-source data fusion model based on conflict optimized DS inference was built,and grouping aggregation of multi-source heterogeneous data was implemented.Finally,an experimental analysis was conducted in a city's distribution network simulation environment to verify the effectiveness of the technology.
