摘要
综合能源系统实现了多种能流的综合管控与协同优化,是未来社会能源系统发展的必然趋势,研究综合能源系统动态特性对综合能源系统科学管理具有重要意义。目前,针对综合能源系统建模仿真的研究已取得很多有价值的成果,但对综合能源系统网络动态传输过程的模拟还存在诸多不足,尤其是特殊流动现象还无法得到很好的模拟。因此,以气—热—电综合能源系统为研究对象,采用模块化的建模方法,基于Modelica和Julia语言建立充分考虑网络动态特性的电—气—热综合能源系统模型,并对输气管道的快瞬变流、慢瞬变流特性以及传输过程的“水锤”“热惯性”等现象进行模拟验证。最后,对综合能源系统负荷变化时不同能流之间的动态响应情况进行仿真分析。结果表明,该方法对描述综合能源系统的网络动态特性以及不同能流之间的动态响应均有良好效果,研究结果可支撑综合能源系统运行优化及多主体在线能流分析等研究,为提高综合能源系统的科学管理能力提供依据。
The integrated energy system realizes the comprehensive control and collaborative optimization of multiple energy flows,which is an inevitable trend in the future development of social energy systems.Studying the dynamic characteristics of integrated energy systems is of great significance for the scientific management of integrated energy systems.Currently,research on modeling and simulation of integrated en⁃ergy systems has achieved many valuable results.However,there are still many shortcomings in simulating the dynamic transmission process of integrated energy system networks,especially for special flow phenomena,which cannot be well simulated.Therefore,this paper takes the gas-heat-electricity integrated energy system as the research object,adopts a modular modeling method,and establishes an gas-heat-elec⁃tricity integrated energy system model that fully considers the dynamic characteristics of the network based on Modelica and Julia languages.The fast and slow transient flow characteristics of gas pipelines and phenomena such as"water hammer"and"thermal inertia"during transmis⁃sion are simulated and verified.Finally,the dynamic response of different energy flows under load changes in the integrated energy system is analyzed by simulation.The results show that the method proposed in this paper has good effects on describing the dynamic characteristics of the network in integrated energy systems and the dynamic response between different energy flows.The research results can support the opera⁃tion optimization of integrated energy systems and multi-party online energy flow analysis,providing a basis for improving the scientific man⁃agement capability of integrated energy systems.
