摘　　要：提出了基于用户需求响应的分时阶梯电价的档位制定方法。利用Stone-Geary效用函数对用户的价格弹性进行差异化分析;先建立单用户对分时阶梯电价的响应模型,再结合全体用户的电量概率密度分布,累积全体用户的响应电量和电费变化量的总和;最后以最大化节约电量为目标,电力公司的电费收益和档位覆盖率为约束条件,计算最优阶梯档位。参考上海地区现行的分时电价和对阶梯电价的相关指导意见进行算例分析,得到分时阶梯电价的一、二档的最优档位,并分析了响应效果和节能效益。A method to determine the tiered levels of time-of-use （TOU） ＆ tiered pricing program based on the demand response is provided. Firstly, the difference in elasticity of consumers is discussed based on Stone-Geary Function; a demand response model is developed to analyze the demand variation caused by the new price, and then the sum of the variation in an area is gained based on the probability distribution of electricity consumption. Lastly, with the object of maximizing the demand reduction, constraints of the cost and coverage range, an optimization model is built to determine the optimal tiered levels. Referring to the TOU price in Shanghai and the relevant scheme of tiered pricing, a TOU ＆ tiered pricing with three levels is designed to estimate its energy saving performance.
