摘　　要：针对目前电能质量定价方法未考虑差异化用户需求层级的问题,提出了考虑不同用户需求层级的增量配电网电能质量定价方法。从电价特征指标入手,提炼了增量配电网的成本特征、电能质量特征和可靠性特征;提出根据增量配电网用户用电需求划分供电服务层级,采用层次分析法确定用户需求层级的方法;通过试点地区的实际增量配电网调研,搭建了增量配电网以电价特征为变量的按质定价电价模型,构建了一种基于用户需求层级的增量配电网电能质量定价方法;通过实际增量配电网算例的搭建,验证了所提方法和策略有效性和适用性,为增量配电网的建设运营提供了新的思路和支持。Considering that the current research neglects the differentiated user demands in power quality pricing,a power quality pricing method for incremental distribution networks is proposed.First,the power cost,quality and reliability characteristics of incremental distribution networks are defined;the power supply service levels are classified according to the user power demands in the incremental distribution networks,and the user demand levels are determined by analytic hierarchy process.Next,based on practical survey in the pilot incremental distribution networks,a power quality based pricing model considering the above characteristics is established,and the pricing method and strategy of power quality based on user demand levels are constructed.Finally,the effectiveness and applicability of the proposed method and strategy are verified by typical case study.New ideas and strong support for the construction and operation of incremental distribution networks are provided.
