Abstract

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.

Key words: energy Internet, digital twin, technology framework, typical application, difficulties and prospects
