|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.
