摘要:

随着传统能源互联系统逐步向能源互联网升级转化,仅基于机理建模的方法难以描述其高维性、非线性以及多能耦合性等特征。数字孪生技术可将真实系统精准映射到虚拟空间,对实现能源互联网的特征描述、运行分析、监控优化以及智能决策具有重要意义。首先,从数字孪生技术的发展出发,对能源互联网中的数字孪生技术体系进行分析,提出了涵盖“多源数据采集-模型构建-平台支撑-智能交互”的分层技术体系框架,细化了数字孪生技术在能源互联网中的应用价值;其次,详细阐述了数字孪生技术在能源互联网中的典型应用以及需要突破的难点,并给出了其当前的发展瓶颈;最后,对数字孪生技术在能源互联网中的发展路线进行了总结与展望。

Abstract:

With the gradual upgrading and transformation of traditional energy interconnection system to energy Internet, it is difficult to describe its high dimensionality, nonlinear and multi energy coupling characteristics if only based on the mechanism modeling method. Digital twin technology can accurately map the real system to the virtual space, which is of great significance to the realization of the feature description, operation analysis, monitoring optimization and intelligent decision-making of the energy Internet. Firstly, from the development of digital twin technology, an analysis is made on the digital twin technology system in the energy Internet, and a hierarchical technology system framework is proposed, which covers “multi-source data acquisition-model building-platform support-intelligent interaction” and the application value of digital twin technology in the energy Internet is elaborated. Secondly, the typical applications of the digital twin technology in energy Internet and the current development bottleneck are introduced in detail. Finally, the development route of the digital twin technology in energy internet is summarized and envisaged.
