能源互联网背景下的多能源输送网络联合建模

Joint Modeling of Multi- Energy Transportation Network under Background of Energy Internet

构建多元多向的能源输送网络、建设清洁能源供应基地,能够提升能源的利用效率,降低能源供应成本,是支撑能源互联网发展的基础和前提。多类型网络的整合与互联,打破了不同类型能源之间的"隔离性",使得各类能源输送网络发展呈现相互依托、相互促进的关系。电力网络与天然气网络作为两大发展成熟的网络,其网络特性以及网络耦合形式值得深入研究探讨。介绍了以电-气联合系统为主的能源输送网的研究现状,总结了不同能源的传输形式以及多种能源输送网络之间的耦合关系,着重分析了电力网络与天然气网络之间的耦合方式,并综合分析了计及不确定性和相关性的多能源输送网络的研究方法。最后,就电-气联合系统的数学模型及实现方式进行论述,并对未来的研究方向以及研究侧重点进行了展望。

Constructing diversified and multi - directional energy transportation network and building clean energy supply base, which can enhance the efficiency of energy utilization and reduce the cost of energy supply is the basis and premise of development of energy interconnection. The integration and interconnection of various types of networks,breaking the ＂isolation＂ among different types of energy, make the development of various types of energy transport network demonstrate the mutual support and mutual promotion. As two major development mature networks, power network and natural gas network, their network characteristics and network coupling form are worthy of further research and discussion. Based on the combination of electric and gas system,the research status of energy transportation network is introduced, the different forms of energy transmission and the coupling relationship among multiple energy transportation networks are summarized, the electrical and gas combined system is emphatically analyzed,and the research method of multi energy transmission network considering uncertainty and correlation is discussed. Finally,the mathematical model of electrical and gas combined system is summarized and the future research direction and research focus are prospected.
