发电侧峰谷分时电价设计及电量分配优化模型

构建发电侧与售电侧峰谷分时电价联动机制有利于平衡发电公司和供电公司之间的利益,但必须建立在定制出合理的上网定价机制的基础上,因此有必要研究发电侧分时电价问题。从发电成本的角度考虑,采用两部制电价对发电侧峰谷分时电价进行研究。应用会计成本法计算发电侧容量成本,并根据发电容量确定峰谷分时容量电价;根据发电厂煤耗等变动成本确定发电侧峰谷分时电量电价,从而得到发电侧峰谷分时电价;构建各时段各发电厂的电量分配优化模型。通过算例分析证明所提出的发电侧峰谷分时电价设计机制及电量分配优化模型是可行的。

Design of time-of-use power price at generation side and optimal model of electricity distribution

The linkage establishment of time-of-use power price between generation and selling sides is based on the establishment of rational net pricing mechanism to balance both sides' advantages.Therefore,it is necessary to research on the time-of-use power price of generation side.It is carried out with two-part power price from generation cost.The capability costs of power plant are calculated using accountant cost method,and the time-of-use capability price is determined according to the abundant degree of power generation.The time-of-use energy price of power plant is determined according to the change cost of power plant such as coal consumption.The time-of-use power price of generation side is thus obtained.The optimal models of electricity distribution to different power plants are established for different periods.A practical case proves the validity of proposed method and model.
