摘　　要：随着我国售电侧改革不断深入,零售市场竞争日趋激烈,制定套餐电价是其中的关键。在我国各省建设电力市场的背景下,推行实时电价零售套餐具有较好的可行性。虽然固定电价和分时电价的应用更为广泛,但实时电价在反映电能价值变化、引导电力消费方面独具优势。在考虑需求弹性的基础上建立了实时电价套餐的非线性优化模型,分别从售电利益最大化、峰谷差最小化等方面对零售套餐合理设计,并基于实际负荷数据进行算例验证,结果表明所提的实时套餐设计可统筹兼顾售电、用户、电网等各方利益,有效释放电力体制改革红利。With the further development of power market de⁃regulation in China,competition in retail market is becoming in⁃creasingly fierce,which has enhanced the importance of retail pack⁃age design.Under the background of many provinces constructing electricity market,it is feasible to carry out real⁃time⁃price retail package.Although fixed price and time⁃of⁃use packages are more widely used,real⁃time price packages enjoy advantages of reflecting the variation of electrical energy’s value and leading power con⁃sumption.On the basis of demand elasticity,a nonlinear optimiza⁃tion model for real time price packages is formulated,with properly designing the real⁃time price packages from the perspective of maxi⁃mizing the retailer’s profit and minimizing the gap of peak⁃valley load.A realistic case study has been conducted,and the numerical results show that real⁃time price packages can take the interests of electric power seller,consumers and power grid enterprises into con⁃sideration,so as to release the bonus of the reformation of electric power system in China.

关 键 词：需求响应 实时电价 电力零售市场 需求价格弹性
