综合考虑供用电双方需求的优质电力用户分类方法

A premium user classification method considering the demand of both power company and electricity user

售电侧开放形成的竞争性售电市场使用户拥有选择权,用户可选择除电网公司以外的售电公司提供电能及相应服务,这将导致电网公司客源流失、市场份额降低。与此同时,随着现代高新技术产业的持续发展,电能质量扰动对用户造成的损失与影响不断增加。因此,电网公司亟需提供满足用户需求的优质电力服务来为有效吸引客源、提升市场竞争力。然而,目前缺乏考虑供用双方需求的用户分类方法,导致优质电力服务的开展进程受阻。通过考虑用户终身价值与电能质量需求,兼顾电网公司与用户综合需求,提出一套新的优质电力用户分类指标体系;同时,基于模糊理论实现数据规范化处理,提出改进k-means聚类算法对海量用户指标数据进行分类,并利用基于熵权的模糊层次分析法实现指标权重计算。最后,通过实例验证该文所提方法所包含的评价信息覆盖较为全面,弱化一般分类方法的主观性,使得优质电力用户分类结果更为客观合理。

Due to the opening of the electricity retailing market,the competitive electricity retailing market allows users choose any electricity company to provide electricity and corresponding services,which will cause the loss of customers and reduce market share of power utilities.At the same time,with the sustainable development of the modern high-technology industries,the loss and impact of the power quality disturbance of users are continuous increasing.Therefore,power companies have necessary to provide high-quality service that meets customer's requirements to effectively attract customers and improve market competitiveness.However,there is a lack of customer classification method considering the demand of both power company and electricity user,which hinders the development of highquality power service.In this paper,a new classification index system of premium users is proposed by considering the lifetime value and power quality demand of users,which combining the comprehensive demand of power grid companies and users.Then,the fuzzy theory is adopted to achieve data standardization,an improved k-means clustering algorithm is proposed to classify the massive user index data,and the fuzzy AHP based on entropy weight is used to calculate the index weight.Finally,the numerical results show that the evaluation information contained in this method is more comprehensive,which weakens the subjectivity of the general method,and make the result classification results of high-quality user more objective and reasonable.
