Energy revolution and digital revolution jointly are promoting the transformation and upgrading of smart grid to energy internet. The traditional model-based methods are difficult to meet the requirements for monitoring analysis and optimal operation of energy internet which has the complex characteristics of multi energy flow coupling and cyber-physical fusion. Digital Twins technology describes and models the characteristics, behaviors, formation process and performance of physical entities and intelligent objects in the real world by using digital technologies such as sensors, Internet of things, virtual reality and artificial intelligence. It is one of the effective way to realize real-time perception, oprating optimization and autonomous evolution of energy Internet. This paper summarized the status of technology research from two aspects of digital twins and energy internet, proposed the overall framework and technical roadmap of energy internet digital twins system(EIDTS), and analyzed the key problems and technologies that need to be broken through in the specific implementation process of typical applications, and finally gave a summary and prospect.
