New Digital Technology for Power System

At present, to achieve the “dual carbon” target, the energy and power sector is the main battlefield and the main position, and the low-carbon transformation of the energy and power industry is an important path and strategic choice. The State Grid Corporation of China comprehensively promotes the wide application of digital technology in all links and fields of the power grid[1], coordinates and promotes the collaborative interconnection of power grid control and information systems, gives full play to the advantages of reliable, timely and safe control systems and the characteristics of intelligence, sharing and interaction of information systems, and meets the needs of safe, real-time and economical new power systems. The rapid development and widespread application of digital twin technology will have a profound impact on energy and power transformation and innovation[2]. This paper analyzes the use of digital twin technology in power system, and uses the digital grid to create a closed-loop enabling system for grid data, realize the interaction between the digital world and the physical world, and create a digital energy ecology[3].
