摘　　要：售电侧放开后,用户拥有自主选择权,电能的商品属性凸显,电能质量决定电价,因此对于售电公司而言,如何根据电能质量合理确定销售电价,是亟待解决的问题。提出一种基于Stackelberg博弈的电能质量定价方法,考虑多个售电公司与多个用户进行博弈,引入消费者参考价格和“自我选择约束”概念建立用户选择模型,在此基础上分别建立用户收益和售电公司收益优化模型,通过Stackelberg博弈求解模型寻找最优电价。算例分析表明基于Stackelberg博弈的电能定价方法能够合理确定销售电价,满足用户电能质量和收益要求的同时保证了售电公司的盈利水平。After the deregulating of the power retail market,the commodity attribute of electric energy is prominent.The price of electric energy is determined by the quality of electric energy,and the user has the right of free option.For power sale companies,how to reasonably determine the sale price according to the power quality becomes a burning question.A power quality pricing method based on Stackelberg game is proposed,which contains multisellers and multiusers.The concepts of internal reference price of consumers and“self-selection constraints”are introduced,and the selection model of users is established.On this basis,the user revenue optimal models and power sale company revenue optimal model are established.Stackelberg game is used to find the optimal price and solve the power quality pricing problem.The case study shows that the proposed power pricing method based on Stackelberg game can reasonably determine power sale price,satisfy the demand of power quality and revenue of users,and ensure the profit level of power suppliers.
