摘　　要：通过对档位和价格弹性模糊化,建立用户对阶梯电价的模糊响应模型,利用模糊优化理论,计算各档阶梯电价调整量及其分布区间。首先将阶梯电价的档位和价格弹性模糊化,利用满意度对用户电量和档位进行模糊数比较,确定用户档位属性的隶属度,将用户的响应描述成各档响应的模糊结果;以最小化全体用户电量为目标,综合考虑电力公司的电费收益及用户电费增长等约束,计算各档电价调整量的模糊优化区间。以上海市区居民用户为例,计算了用户响应后的电量变化区间,证明了模糊响应分析的合理性;证实了阶梯电价具有一定的节能效果并分析了档位和价格弹性对阶梯电价的影响。A fuzzy demand response model for electricity tiered pricing is established with the fuzzification of price tiers and price elasticity;the fuzzy optimization theory is applied to calculate the tiered price variation and its distribution range.Firstly the price tiers and price elasticity are fuzzified and the fuzzy numbers of customers＇ electricity demand and tiers are compared with respect to the degree of customer satisfaction,therefore the membership of users to different tiers is determined,and the users＇ response is described as the fuzzy result of each tier＇s response.Then with a view to minimizing the total electricity demand and constrained by the power charge profit for power companies and the electricity price increase for users,the fuzzy optimization range of the tiered price variation is calculated.A case study has been made in Shanghai in order to calculate the demand response range,and the calculation results verify that the fuzzy demand response analysis is reasonable,and that tiered pricing has energy-saving effects.Finally, the research analyzes the impacts of the tiers and price elasticity on tiered pricing.
