摘　　要：综合能源系统(IES)熵态机理与分析方法为面向可再生能源集成的IES能量品质分析提供了一种新的理论基础。针对不同的能源系统规模和场景,如何系统性求解大规模能源系统熵态分布是后续系统规划、运行和能量管控等亟须解决的基础问题之一。在IES熵态理论的基础上,进一步梳理了系统熵态分布的计算体系与思路;根据熵增流求解的需要,定义了一些关键计算矩阵与计算列向量;结合IES㶲流模型和熵态网络的定义,考虑能量枢纽(能源站)熵增流转化与分配机制,建立了基于顺序求解和联立求解的IES熵态计算模型,通过算例验证了两种计算模型的正确性与有效性,并讨论了两种计算方法的异同与适用性。The entropy state mechanism and analysis method of the integrated energy system(IES)provides a new theoretical basis for the analysis of IES energy quality for renewable energy integration.For different energy system scales and scenarios,how to systematically solve the entropy state distribution of large-scale energy systems is one of the basic problems that need to be solved urgently in subsequent system planning,operation,and energy management and control.On the basis of IES entropy state theory,the calculation system and ideas of the system entropy state distribution are further sorted out.According to the needs of solving the entropy increase flow,some key calculation matrices and calculation column vectors are defined.Then,combined with the definition of IES exergy flow model and entropy state network,considering the entropy increase flow conversion and distribution mechanism of energy hub(energy station),the IES entropy state calculation models based on sequential solution and simultaneous solution are established.The correctness and effectiveness of the two calculation models are verified by cases,and the similarities,differences and applicability of the two calculation methods are discussed.
