随着能源与环境危机日益严重,如何建立精确调度模型成为电力市场逐步完善过程中的一个迫切需要研究的课题.目前广泛采用的建模方式是将时间离散化,建立离散时间调度模型,本文首先举例说明离散时间调度模型中所定义的备用容量上、下限存在不可达的情况,即离散时间调度模型中的备用容量上、下限约束条件不严格,从而造成实际调度时存在旋转备用容量无法满足实际需求的情况.通过对机组出力方式与爬坡率关系的详细分析,证明了任意调度时段内机组精确可达的备用容量上、下限与该时段首末时刻机组输出功率相关,并给出了精确可达备用上、下限的

通过煤的部分气化制备了煤在不同加热终温下的半焦,详细分析了原煤和不同半焦的干燥无灰基挥发分含量,提出预测煤部分气化后生成半焦残余挥发分含量的新方法,即采用两个燃料特性参数FV和FC来分别表征挥发分二次析出特征温度和完全析出时的特征温度,这样根据原煤的工业分析和元素分析数据,就可以简单可靠地预测不同加热终温下所制得半焦中的残余挥发分含量.
