摘要
To realize the multi-gradient utilization of energy and reduce environmental pollution, the integrated energy system (IES) coupling with electricity and natural gas generally occupies a significant part of the global energy structure. To clarify the operation characteristics of the system and fully tap the dispatching potential of the energy sub-network, the dynamic simulation researches of the integrated energy system are gradually deepened. In the natural gas network, the pipeline transmission process has a profound impact on its dynamic process. However, the existing pipeline transmission process time-domain simulation algorithms have a dilemma of accuracy and efficiency. To handle the above problems, a dynamic simulation algorithm of integrated energy system gas network based on time-domain two-port model is proposed. First, based on the characteristic method, the source-load node relationship matrix of the gas network is constructed, and the time-domain two-port model is further given. Then, referring to the numerical format of the characteristic method, the spatial distribution matrixes of the state quantity are constructed to obtain the state quantity distribution of the gas network, and a dynamic simulation algorithm of the gas network based on the time-domain two-port model and distribution matrixes is proposed. The numerical results show that the proposed method has two advantages of high efficiency and high accuracy, and it is suitable for the long-term simulation of the integrated energy system with gas-electric coupling. ©2024 Chin.Soc.for Elec.Eng.
