摘要
能源革命和数字革命共同推动我国智能电网向能源互联网转型升级。能源互联网具备多能流相互耦合、信息物理融合等复杂特性,传统基于机理物理模型的方法难以满足其监测分析及优化运行的要求。数字孪生技术利用传感器、物联网、虚拟现实、人工智能等数字技术对真实世界中物理实体和智能实体对象的特征、行为、形成过程和性能等进行描述和建模,是实现能源互联网实时感知、运行优化及自主进化的理想途径之一。该文主要从数字孪生及能源互联网两方面总结技术研究现状,提出了能源互联网数字孪生系统的总体框架及技术路线,分析了典型应用在具体实施过程中需突破的关键问题及技术,并进行了总结与展望。
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.
