【摘要】 为适应节能减排,在传统机组组合模型的基础上,提出一种联合循环机组模型。该模型的建模难点在于联合循环机组的多模式运行特性以及各模式间的转移关系。针对这一难点,提出一种综合考虑模式转移关系及由此产生的转移成本的模型。通过引入模式转移矩阵,该模型能更加简洁、直观地描述模式转移特性。利用单台联合机组出力分配和IEEE118节点系统(12台联合循环机组和54台普通机组)对该模型进行测试。测试结果表明该模型易于与传统机组组合模型结合,并能有效解决联合循环机组模式转移及出力分配问题。更多还原

【Abstract】 A combined cycle gas turbine (CCGT) model based on conventional unit commitment (UC) is presented in order to achieve energy savings. The CCGT has various operation modes. It is difficult to model the multiple operating modes and mode transitions. Considering these difficulties,a model is presented which can handle the modes in transition as well as the transition cost very well. Furthermore,this model which uses the transition matrix is much more compact than those reported in previous publication. A single CCGT scheduling and IEEE 118-bus system including 12 CCGTs and 54 thermal units are simulated. The results show that the presented CCGT model can be easily combined with the conventional UC model,and it is effective to schedule the CCGT and deal with the mode transitions.更多还原
