摘要(Abstract)：

针对综合能源利用效率,区别于传统能源效率计算,提出基于热力学第二定律的综合能效计算方法,首先建立考虑能源能质系数的工商业园区模型,能源的利用效率不仅要从数量上,更要从质量上考虑,以综合能源效率最大和碳排放最小为目标函数,结合加权法在MATLAB/Cplex软件上进行求解。结果表明,系统中加入能质系数后,可更加准确地衡量各设备的出力情况,在多目标分析中,考虑能质系数能够有效减少碳排放并且可提高能源的梯级利用。
In view of the difference between comprehensive energy efficiency and the traditional calculation of energy efficiency, a calculation method of comprehensive energy efficiency based on the second law of thermodynamics is proposed. Firstly, an industrial and commercial park model considering the energy-quality coefficient is established. The energy utilization efficiency not only lies in quantity but more in quality. In combination with the weighting method, MATLAB/Cplex is used to solve the objective function with maximum comprehensive energy efficiency and minimum carbon emission. The results show that adding an energy quality coefficient into the system can more accurately measure the output of each piece of equipment; considering the energy-quality coefficient in multi-objective analysis can effectively reduce carbon emissions and improve the cascade utilization of energy.
