Modeling and Calculation Methods for Multi-energy Flows in Large-scale Integrated Energy System Containing Electricity,Gas,and Heat
摘要
Abstract
To improve the energy utilization efficiency and realize the supply of clean energies,integrated energy sys-tem(IES)has become an important technology for supporting the transition of the energy structure. Therefore,the study of the coupling mechanism of multi-energy flows in the IES is significant to the planning,optimization,and analy-sis of the subsequent system. In this paper,a multi-energy flow calculation method for a large-scale IES containing elec-tricity,gas and heat networks is proposed. First,the steady-state mathematical models of electricity,gas,and heat net-works are established,respectively. Then,the mathematical formulation of the coupling links in the IES is established based on the unified energy bus model. On this basis,the Newton-Raphson method is used to realize the decomposed calculation of multi-energy flows in the large-scale IES. Finally,the effectiveness of the proposed method is verified through the analysis of a numerical example.关键词
