中文摘要：
在分析发电侧峰谷电价与峰谷电量关系的基础上，分别提出了在实行发电侧峰谷分时电价情况下，保持平均上网电价不变和保证发电机组收入增量处于某一水平的必要条件。然后将发电机组的上网电量及其在峰、平、谷时段的电量分配问题纳入到发电侧峰谷分时电价的优化设计中，并以发电总耗能最低为目标函数，建立了发电侧峰谷分时电价设计的优化模型。在此过程中，根据不同类型机组的相对环境价值设置了发电机组收入增量参数。算例结果表明了该优化模型的有效性。
英文摘要：
On the basis of analyzing the relation between peak-valley prices and peak-valley electricity quantity at generation side, the necessary conditions of keeping the average pool purchase price unchanged and maintaining the income increment of generating units on a certain level are respectively proposed while the peak-valley time-of-use （TOU） price is implemented at the generation side. Then the purchased electricity quantity of generating units and the allocation of electricity quantity in peak, average and valley time periods are brought into the optimal design of peak-valley TOU price at generating side; and taking the lowest total energy consumption in power generation as objective function, an optimal model for the design of peak-valley TOU price at generation side is built. During this process, according to the relative environmental values of various kinds of generating units the income increment parameters of generating units are set up. The effectiveness of this optimal model is validated by the results of calculation examples.
