摘　　要：提出了一种区域电网节能发电调度的算法模型,利用该模型可以制定各省市的日发电计划。该算法首先确定开机机组组合,然后确定跨省交易电力,最后确定机组的发电量和发电曲线。然后根据这个模型,利用实际的区域电网进行了跨省交易电量分析,得出了采用设计煤耗进行节能调度会引起"煤电倒流"的问题,建议采用考虑电煤运输损耗等因素的综合煤耗作为节能调度机组排序的依据。最后对组织实施节能发电调度提出了一些问题和建议。This paper proposes a novel energy-saving generation dispatching model in regional grid which can be used for daily generation scheduling. The first step is to find the unit commitment, and then the power of trans-provincial transaction is confirmed. Finally, the generated energy and generation curves are determined to every unit. The model is used to analyze the trans-provincial transaction in regional grid of Central China. It is found that the backflow of power and coal is occurred when energy-saving generation dispatching used designing coal consumption rate. For that the comprehensive coal consumption rate considering the coal loss in transmission and other aspects are adopted to range the units. Some problems and advises of energy-saving generation dispatching operational mechanism are given in the end of this paper.
