摘要
冷热电联供(CCHP)通过对能源的梯级利用,提高了一次能源的利用效率。考虑到环境温度的变化,对系统内微型燃气轮机的效率和功率曲线进行了温度修正,并且建立了含燃料成本、环境成本和维护成本的多目标调度模型。针对具体的算例,使用Matlab优化工具箱中的fmincon函数对上述模型进行寻优计算。最后的优化结果证明了该系统的经济性。
CCHP system, based on energy cascade, was used to improve energy-saving efficiency. Taking into account ambient temperature, the efficiency and power curve of micro-turbine were amended in the system and a multi-objected scheduling model with fuel cost, environmental cost and maintenance cost was established. In addition, this study used the fmincon function of MATLAB optimization toolbox to calculate according to the specific examples. The final optimization results verify the economy of the system.
