On September 28, 2021, the comprehensive performance evaluation meeting of “Basic Theory of High-Proportion Renewable Energy Grid-Incorporated Power System Planning and Operation”, a keyspecial project of the national key research and development program “Smart Grid Technology and Equipment”,was held in Nanjing. The projectwas carried out bya university + enterprise dual-leader system. The project leader is Professor Kang Chongqing,Dean ofthe Department of Electrical Engineering of Tsinghua University, and the project leading unit is China Electric Power Research Institute Co., Ltd. The project team composed of Tsinghua University andthe other17 participating units has passed the comprehensive performance evaluation of the Ministry of Industry and Information Technology after five years of close cooperation and joint research. The meeting was hosted byNo. 3 Special Project Division of the Industrial Development Promotion Center of the Ministry of Industry and Information Technology. Liu Jia, Deputy Director ofNo. 3 Special Project Division, an expert group headed byProfessor-level Senior EngineerLiu Jianming of the Chinese Society for Electrical Engineering, Science and TechnologyDivision of the State Grid Corporation of China, the project leading unit China Electric Power Research Institute Co., Ltd.,theproject leader Professor Kang Chongqing, projectsubjectleaders andmajor members of the project attended the meeting.

The“Basic Theory of High-Proportion Renewable Energy Grid-Incorporated Power System Planning and Operation” is the firstproject of the first batch ofspecial keyprojects of the national key research and development program “Smart Grid Technology and Equipment” during the “13th Five-Year Plan” period. Facing themajor challenges of “great uncertainty” and “power electronization” in the power system of renewable energy and centered atscientific issues of high-proportion renewable energy gridincorporation and safe and efficientsystemoperation,the project has made a series of important innovations inthe basic theory of coordinated planning and optimized operation of the power system: it put forwarda futureoriented flexibility theory for the analysis of high-proportion renewable energy power system morphology evolution, a security boundary theoryof high-permeability renewable energy distribution network oriented tosource-grid-load flexible planning and operation,a there for the analysis ofmulti-scale dynamic interaction mechanism and stability ofsource-grid-load highly electronized power systems, high-proportion renewable energy power system panoramic operation simulation theory and planning and operation methods under AC/DC hybrid;it publishedstandard calculation examples for the flexibility,transmission grid planning and distributiongrid planning research of high-proportion renewable energy power systems in the world;itdevelopedsoftware platforms forenergy power morphology evolution and supply and demand analysis, transmission grid planning, distributiongrid planning, and power system operation simulation and so on, and constituted an experiment platform for the dynamic simulation of electronized power systems;it alsopublished 2 IEC international standards, 122 SCI search papers,21EI search papers, published 9 academic monographs, applied for 63 invention patents,andcultivated 60 doctoral students and 97 master students. The projectachievements, which have been applied in many placesin Northwest China, are prospective for extensive application and significantly influencing in the world.They caneffectivelysupport the overall goal of thespecial key project“Smart Grid Technology and Equipment”,promotelarge-scale gridincorporation andconsumption of renewable energies,acceleratesmart grid technology innovation,advance the clean transformation of energy structure and energy consumption revolution, andprovide a theoretical foundation for the carbon peak and carbon neutrality of China.
