| 摘 要： | 为减少能源消耗,电力工业在发电侧推行节能发电调度,而在用电侧则施行需求侧管理。事实上,发电侧与用电侧可以通过联合优化实现更好的节能效果。峰谷分时电价将改变原有系统负荷的分布,发电侧机组发电调度的安排将随之改变,发电煤耗水平也将相应地变动。有鉴于此,首先分别构建了需求侧峰谷分时电价响应分析模型以及发电侧节能发电调度的机组组合模型;其次,为了实现分时电价响应向机组煤耗效益的传递,以机组发电煤耗与启停煤耗最少为目标构建了需求侧与发电侧的联合优化模型;最后,通过算例分析发掘模型的节能效益,借助GAMS求解上述模型,优化结果表明分时电价的优化将有助于改进发电侧的节能调度效果,同时将实现一定的环境效益。

| Abstract: | To reduce energy consumption in power industry, energy saving generation dispatching is carried out on the generation side, and DSM is implemented on the user side. In fact, joint optimization of the generation side and user side could achieve better energy saving effect. With the implementation of Time-of-Use(TOU)price, the original system load distribution pattern will be changed, dispatching allocation of power generation units in power generation side will be changed, and coal consumption level of power generation will also vary. Considering above relationship between system load and coal consumption, demand response analysis model about TOU price in power demand side and unit commitment model of energy-saving generation dispatching in power generation side are established. To realize the impact transfer of TOU price to unit coal consumption, integrated optimization model of power generation side and power demand side is constructed, with objective function of minimizing the coal consumption of unit operation, start-up and shut-down. Finally, the energy saving benefit of the optimization model is showed by a case study, and the simulation analysis using general algebraic modeling system(GAMS)shows that TOU price optimization will help to improve the effect of energy-saving dispatching in power generation side and realize certain environmental benefit. |
