基于可中断负荷的机组组合优化调度模型
摘要：机组组合是制定日前调度计划的重要内容,主要是确定机组的有功出力和启停状态。在智能电网大力建设背景下,需求响应成为重要的互动资源,本文综合考虑电源侧与负荷侧的特点,比较不同需求响应手段的使用范围,选取可中断负荷并将其作为一种虚拟的发电资源,融入到机组组合中,建立优化调度模型。算例结果表明,所建模型有效降低了系统运行成本,减少效率差的小型机组的频繁启停,同时用户还获得收益,说明考虑可中断负荷的机组组合优化调度模型有利于电力系统的可靠经济运行。
Abstract:Unit commitment is of great importance for daily dispatching, mainly for determining the active power output and start-stop state of the unit. The traditional unit combination is hard to solve new problems of scheduling. In the context of efforts to build the smart grid, demand response has become an important interactive resource. In this paper, the characteristics of the power supply side and load side is comprehensively considered, and application range of different demand response is compared. The interruptible load is selected and regarded as a virtual generation resources by integration of unit commitment, and an optimized scheduling model is built. Numerical results show that the model effectively reduces system operation cost and the start and stop frequency of low-inefficient small units. At the same time, consumers also can gain profit, which indicates that unit commitment optimization model by considering of interruptible load is benefit for economic and reliable operation of power system.
