Bearing in mind the earnest wishes of General Secretary Xi Jinping, Nanrui's science and technology workers have ventured into the "no man's land" of science and innovation, occupied the technological commanding heights, and actively provided "Chinese solutions" for the world's power problems.
At the end of November 2023, 14 scientific and technological achievements of Nanrui Group passed the appraisal organized by the Chinese Society of Electrical Engineering - the core technologies all reached the international leading level.State Grid Corporation's chief expert, Nanrui Group's chief expert Xue Feng led the "grid security and stability control system information security protection key technologies and equipment project" is one of them.
A power grid that turns nature's "gifts" into "green power" and delivers it to thousands of households every day.A variety of new energy in the complex power grid shuttle, China's power grid how to keep the record of "more than 20 years without a large area of power outages"? One of the secrets is the "grid security and stability control system".Xue Feng's "grid security and stability control system information security protection key technology and equipment project" is equivalent to the power grid to add a "firewall".
It is reported that the "grid security and stability control system" is an integrated secondary control system covering the extra-high voltage AC and DC networks, which used to be a technical "no man's land" at home and abroad. Xue Feng has been rooted in this field since he joined the work, he and his teammates with "ten years to sharpen a sword" perseverance to overcome the difficulties, and become a guardian of grid security technology.At the beginning of this year, he was honored by the Party Committee of the State-owned Assets Supervision and Administration Commission of the State Council as the "Model of Central Enterprises" for the year 2023.
Looking back on the footprints of the past year, Yang Yu, director of the Science and Technology Information Department of Guodian Nanrui, a listed company belonging to the State Grid Nanrui Group, said, "Keeping in mind the mandate, we are grateful to make progress, and have made a series of new breakthroughs in major technology research. Academician Xue Yusheng led a team that pioneered a hybrid simulation-based optimization method for power systems to actively support energy transition. At the same time, Nanrui Group put forward a new principle of protection that does not depend on the characteristics of the power supply, and made a milestone breakthrough in the research of key core technologies, such as high-altitude multi-terminal flexible DC transmission, and explosion-proofing of faults of large-scale oil-filled equipment of extra-high voltage. We have developed the world's first set of controllable phase-change converter valves, grid safety and stability adaptive emergency control system, and built the first set of inter-provincial spot power purchase auxiliary decision-making system, etc."

On April 1 this year, Xiongan celebrated its seventh birthday. In the past seven years, the construction of Xiongan New Area has been changing day by day, behind which there are the sweat of Nanrui people. The State Grid Xiongan Innovation Center Intelligent Zero Carbon Demonstration Park is a project with "green" as the background color and "ideal into the future". Nanrui Group undertook four types of typical demonstration work, such as clean energy saving and low carbon, load flexibility and interaction, electric carbon trading in the park, and intelligent operation in the park, and created the first complete set of mature and landed intelligent zero-carbon park solutions in Xiong'an New Area.
Nanrui people have always been active in the construction of major projects and the protection of major events in China.Since last year, with the fully localized core technology and equipment, Nanrui Group has helped Zhumadian-Wuhan and other six UHV, Henan Tianchi and other six pumped storage power station, Zhejiang 220kV flexible low-frequency transmission and other major projects to be constructed and put into operation on schedule. In the "Belt and Road" International Cooperation Summit Forum, Shanghai Expo, Hangzhou Asian Games, Chengdu Universiade and other events, Nanrui people also silently undertake major power protection tasks.
At present, a reform of the scientific research system is being accelerated by Nanrui Group. Yang Yu revealed: "We face the new situation and new requirements of the construction of the new national energy system and new power system, completed the overall optimization of the scientific research system of 'a committee, two levels, three poles of the structure', to further build research 'incremental ', activate R&D 'stock', and strive to create a new situation where research and R&D are given equal importance, and research and industry are mutually promoted."
