摘要:
在售电侧放开的市场环境下,为满足配电网高渗透、分散化敏感用户的差异化优质电能需求,提出一种电能质量分级与差异化电能质量购售电决策方法。给出一种考虑敏感用户需求的负荷聚类和电能质量等级划分方法;搭建售电企业和集群用户之间的购售电决策主从博弈框架,考虑电能质量敏感度构建集群用户博弈模型,计及治理成本和治理回收率构建售电企业收益模型。算例结果表明,所提方法有利于提高电能质量治理的针对性和适用性以及提高市场主体的经济效益,为敏感用户差异化用电需求提供了解决方案。

Abstract:
Under the environment of deregulated power retail market, in order to meet the differentiated high-quality power demand of highly permeable and decentralized sensitive users of distribution network, a power quality gradation and power purchase and sale decision making method for differentiated power quality is proposed. A load clustering and power quality gradation method considering sensitive users’ demand is given. A master-slave game framework for power purchase and sale decision making between power selling enterprise and cluster users is established, a game model of cluster users is established considering power quality sensitivity, and a revenue model of power selling enterprise is established considering management cost and recovery rate. Simulative results show that the proposed method is beneficial to improve the pertinence and applicability of power quality management and improve the economic benefit of market entities, and provides solution for sensitive users’ differentiated power demand.
Key words:  differentiated power quality  power purchase and sale strategy  gradation  master-slave game  sensitive device
