峰谷分时电价设计的优化模型

峰谷分时电价是实施需求侧管理的措施之一,有利于削峰填谷,其效果依赖于科学的峰谷时段划分和合适的分时电价。文中利用电价理论及有关经济学原理阐述了实行峰谷分时电价对于供电企业和用户的经济意义、峰谷分时电价的结构及时段的划分方法。在此基础上,给出了峰谷分时电价设计的目标函数,并参考一般用户的反应模型建立了用户对分时电价的反应模型。通过对该模型的需求侧管理目标函数进行优化,得出了最优时段划分及其相应的分时电价定价方法。对算例进行了仿真,说明了峰谷分时电价的具体实现过程。

Research on TOU Rate Design Optimization Model

As one special time-of-use(TOU)rate,peak and valley time price is one of the measures for implementing demand side management(DSM) and beneficial to flattening the load curve if the peak and valley time periods are partitioned appropriately.The economical significance for the power suppliers and customers,the structure of TOU rate based on peak-valley,and the peak and valley time period partition approach are expounded by using price theory and economics theory.A TOU price target model is proposed based on the previous analysis,a model of the customer demand response to the TOU is thus presented from many references to a general customer demand response model.A new approach to peak-valley time-period partitioning and TOU rate setting is thus presented by optimizing the TOU price model as above of performance function in DSM.The numerical simulation results show that the method is feasible and reasonable.
