摘要(Abstract)：

随着微型燃气轮机发电技术和电转气技术的发展,电力系统与天然气系统之间的耦合不断加深。为了分析电力系统和天然气系统在动态运行过程中的相互影响,针对一个电-气互联的终端能源系统进行建模和仿真研究。建立了包含微电网、天然气供应网络、以微型燃气轮机发电系统和电转气系统为核心的电/气耦合环节的数学模型;在MATLAB/Simulink仿真平台上搭建了系统的仿真模型,研究了微电网动态过程对天然气供应网络的影响。算例仿真结果表明,所搭建的系统模型可以有效反映微型燃气轮机发电系统和电转气系统参与微电网动态过程调节时天然气管道内气体状态的动态变化过程。
With the development of micro-turbine generation technology and power-to-gas technology, the coupling between electric power system and natural gas system continues to deepen. In order to study the interactions between electric power system and natural gas system in the process of dynamic operation, modeling and simulation of an electric power-natural gas interconnected terminal energy system is studied in this paper. First of all, mathematical models of the micro-grid, the natural gas supply network, and the coupling units including micro-turbine generation system and power-to-gas system in the terminal energy system are respectively built. After that, simulation model of the system is set up on MATLAB/Simulink platform, and influence of dynamic process of micro-grid on natural gas supply network is mainly researched. The simulation results show that the established model can reflect dynamic gas change in the natural gas pipeline when the micro-turbine generation system and the power-to-gas system participate in the dynamic process regulation of the micro-grid.
