Abstract

Combined Cooling, Heating and Power (CCHP) system, as a typical form of Integrated Energy System (IES), enhances the coupling of cooling, heating and power network. In this paper, a sequential method for multi-energy flow calculation of CCHP-IES is proposed based on two-stage integrated energy system composed of district and terminal CCHP system. Firstly, the mathematical models of heating and power network are established respectively. Secondly, a more detailed terminal cooling network model with cold airflow as transmission medium is developed based on the general laws and the heat transfer characteristics of pipeline in fluid mechanics, aiming at increasing the accuracy of energy flow calculation results. On this basis, an energy flow calculation model of CCHP-IES is constructed. Numerical case analysis shows that the proposed terminal network model can improve the accuracy of the energy flow calculation, and the sequential method can reduce the convergence time to no longer than 0.236s.
