【摘要】 在电力市场环境下，如何制定合理的电价显得十分重要，此电价必须正确的反映电力系统发电和运行成本。作为最终用户电价的一种，分时电价目前在世界各国得到了普遍的采用。同时作为一种有效的需求侧管理手段，有利于削峰填谷，平滑系统的负荷。但是分时电价实施的效果依赖于合适的峰谷时段划分和相应的峰谷电价。本文基于负荷曲线分布分析，利用模糊半梯度隶属度函数方法，从负荷曲线上各点分别处于峰时段和谷时段的可能性入手，提出了一种含有用户对分时电价反应度分析的分时电价模型，通过对该模型需求侧管理的目标函数进行优化，得到了最优化的分时电价，包括峰谷时段划分及其相应的峰谷电价。文中对—算例进行了仿真、分析，说明了本文所提方法的可行性。更多还原

【Abstract】 In the power market environment, it is important to establish the appropriate price of electrical energy. It should reflect the generate electricity and other operation cost. As one of the price for end user, time-of-use (TOU) tariff is used by most country of the world. At the same time, it is one of the most efficient measures for modem demand side Management (DSM). It is very beneficial to flat the load curve if the peak and valley time periods are partitioned appropriately and the peak and valley price is also appropriate. Based on the analysis of the possible point-wise peak-valley distributions of load curves via fuzzy semi-gradient subordinate degree function method, a TOU price model is proposed in this paper with consideration of the response-model of various users in demand side. A new approach of peak-valley time-period partitioning and peak and valley price setting is thus presented by optimizing the above TOU price model under the performance function in DSM. The numerical simulation results show that the new method is feasible and reasonable.更多还原
