摘要
在现代电网中电压暂降问题日益突出的背景下,精准识别用户电压暂降治理需求,对于指导用户电压暂降治理精准投资决策和帮助电网公司明确优质供电增值服务对象具有重要工程意义。首先,以多属性用户数据为基础,兼顾用户电压暂降治理需求与电力公司服务意愿,建立了包含用户电压暂降过程特征与服务特征的电压暂降治理需求画像标签体系,全面描述电力用户与供电公司之间的供需关系;其次,利用模糊C均值聚类算法进行用户群体画像,实现用户群体特征刻画和分类;然后,基于熵权法计算用户二维指标综合评分,刻画用户电压暂降治理需求并明确电力公司优质服务对象群体;最后,基于我国某市配电网的107家企业用户数据,验证了所提方法的合理性和有效性。
Under the background of the increasingly prominent voltage sag problem in modern power grids,it is of great engineering significance to accurately identify the users' profile of demand of voltage sag control for guiding users' precise investment decisions for voltage sag control and helping power grid companies to identify the objects of premium power supply value-added services.Based on the multi-attribute user data,taking into account the users' demand of voltage sag control and the service willingness of the power companies,a voltage sag demand portrait label system including the users' voltage sag process characteristics and service characteristics was established,which comprehensively describes the supply and demand relationship between power users and power companies.Secondly,the fuzzy C-means clustering algorithm was used to make user group portraits in order to realize the characterization and classification of user group characteristics.Then,based on the entropy weight method,the comprehensive score of the users' two-dimensional indicators was calculated to describe the users' voltage sag control demand and clarify the premium user group of power companies.Finally,based on the user data of 107 enterprises in the distribution network of a city in my country,the rationality and effectiveness of the method proposed were verified.
