According to the promotion of the national “dual carbon” goal, the construction of a new power system has become an inevitable trend to achieve energy transformation and the mission of the power industry. The new power system adapts to a high proportion of renewable energy access, adapts to the instability of new energy, adapts to a high proportion of power electronic equipment, adapts to the coordinated operation of smart dispatching of multiple energy sources, and adapts to more flexible active power consumption characteristics. The new generation of information communication and digital technology is deeply integrated. The application of digital twin technology in the power industry empowers smart grids and smart power plants, provides more real-time, efficient, and intelligent service value, effectively promotes the digital transformation of power companies, and promotes the construction of new power systems.
At present, the digital economy has become a hot spot in global development. Countries around the world have proposed digital economy development strategies, and digital twin technology and social and economic development have been continuously integrated and deepened. “The 14th Five-Year Plan for National Economic and Social Development of the People’s Republic of China and the Outline of Vision 2035” proposed: “Accelerate the promotion of digital industrialization. Cultivate and strengthen artificial intelligence, big data, blockchain, cloud computing, network security, etc. Emerging digital industries.” The “14th Five-Year Plan for Digital Economy” issued by the State Council listed digital twin technology in “accelerating the promotion of digital industrialization” as a strategic strategy for enhancing the innovation capabilities of key digital technologies and strengthening the supply of superior technologies. The forward-looking new field is also the field of innovative technology integration that is a key breakthrough in the “14th Five-Year Plan” period.
This white paper first analyzes and expounds the application value of digital twin technology in the power industry from the perspectives of production, education, research and application combined with the characteristics of the power industry. It introduces the application status and typical applications of digital twin technology in the power industry, and sorts out the common problems and application trends faced by the current development of digital twin technology in the power industry, and puts forward strategies and suggestions for the next construction and implementation. Finally, by sorting out the application and development of digital twin technology in the power industry, it analyzes the application hotspots, industry trends and future trends of digital twin technology, and puts forward relevant standardization work requirements.
This white paper is led by the Science and Technology Development Service Center of China Electricity Council, and jointly released by the Digital Department of State Grid Corporation of China, the Digital Department of China Southern Power Grid Co., Ltd., the Department of Science and Information Technology of China Datang Corporation, and the Planning Institute of the China Academy of Information and Communications Technology. Experts from multiple fields of digital technology research such as twinning participated in the compilation, condensing the wisdom and hard work of experts, and I would like to express my heartfelt thanks to the experts who participated in the compilation! At present, digital twins are a key technology to promote digital transformation, and the electric power industry has a lot to do with digital technology. Preliminary exploration and trial of the application of twin technology, continuous exploration and iteration for the application of digital twin technology in various professional fields such as power generation, transmission, substation, distribution, etc., need to further build consensus and summarize and refine, errors are inevitable in the writing process, please also The majority of readers provide valuable comments and suggestions.
