Who is stronger in smart grid?
In 2021, Jiangsu Nanjing smart grid industry won the advanced manufacturing cluster competition of the Ministry of Industry and Information Technology and became the "national team" of the advanced manufacturing cluster; In 2022, Nanjing launched an action plan to build a 500 billion-level smart grid industrial cluster; In June this year, the Nanjing Action Plan for Promoting a Strong Industrial City (2023— 2025) proposes that by 2025, Nanjing smart grid will become a leading world-class industrial cluster in China. From leading the country to competing for the world, Nanjing has industrial ambitions.
Nanrui Group is undoubtedly the flagship of this industrial aircraft carrier. In 2022, the industrial scale of smart grid cluster in Nanjing reached 268 billion yuan, of which Nanrui Group realized operating income of 47.8 billion yuan, up 16.3% year-on-year.

On the afternoon of July 6th, General Secretary of the Supreme Leader came to Nanrui Group in Jiangning Development Zone, Nanjing for investigation and study, listened to the general introduction of Nanjing’s national advanced manufacturing cluster of smart grid, and looked at the display of independent and controllable technology products of enterprises.
A few days ago, People’s Daily reporter walked into Nanrui Group, and the book on the wall of the exhibition hall read the important instructions of the General Secretary during his inspection: "Energy security and safety are related to the national economy and people’s livelihood and cannot be ignored for a moment ‘ The big country ’ " "It is necessary to accelerate the iterative upgrading of key technologies and core products and the empowerment of new technology wisdom to improve national energy security and support capabilities".
Heart is "the country’s greatest"
Nanrui Exhibition Hall is the first stop for General Secretary of Supreme Leader to visit Nanrui Group. Here we can see the development course of Nanrui Group: it developed from Nanjing Institute of Automation, Ministry of Electric Power, which was established in 1973. Through the continuous efforts of several generations of scientific and technological personnel, it has won 86 national-level scientific and technological awards, and achieved international leadership and independent control in important sectors such as UHV, large power grid security and stability, power grid dispatching automation and relay protection.
From lighting the light bulb to lighting the industry, the new power system has developed into a huge and complex industrial system, and its safe and stable operation is a "national power" and a world-class problem. In the exhibition hall of Nanrui, the 10 characters of "Guardian of Safe Operation of Power Grid" are particularly eye-catching. Such confidence comes from the power grid safety and stability device and control system developed by Xue Yusheng team of Nanrui Group.
Xue Yusheng, who is 82 years old, is an academician of China Academy of Engineering trained by Nanrui Group. He has been engaged in the research of power system stability theory and power system automation since he studied PhD in 1985. In his view, the "newness" of the new power system lies in the need to adaptively respond to the uncertain state and events in various related fields, and also in meeting the multi-objective optimization needs in different fields, etc. "This requires us to carry out a large number of innovative work at the source and solve problems one by one."
However, the process of tackling key problems in scientific research is arduous, not only to sit on the "cold bench", but also to bear the doubts of the industry sometimes. Xue Feng, chief expert of State Grid and director of the system protection laboratory of Nanrui Group, joined the Xue Yusheng team in 1992. He still remembers that Xue Yusheng used "self-knowledge, loneliness" as his motto to encourage the team. Based on the actual needs of the safe and stable operation of the power grid, they simulated various states of the power grid operation, constantly tried various parameters for theoretical derivation, and repeatedly verified the new method.
It takes ten years to sharpen a sword, and hard work pays off. Today, the WARMAP system developed by Xue Yusheng team has covered more than 90% of the provincial power grids in China, and established a comprehensive advantage in the field of power outage early warning system for large power grids.
In recent years, Nanrui Group has also achieved a gorgeous turn from "following" to "leading" in the UHV field. It is understood that Nanrui Group has broken foreign blockades and achieved international leadership in technologies such as UHV, flexible HVDC transmission, large power grid security and stability, power grid dispatching and relay protection, and its products and services have been delivered to more than 110 countries and regions around the world.
"Run one stick after another"
The sun is burning outside the window and the indoor atmosphere is warm. Jin Yulong is discussing some key technical difficulties in the research and development of virtual power plant system with his colleagues. Since he joined the Power Grid Application Research and Development Center of Nanrui Research Institute for four years, he has devoted almost all his body and mind to this project.
"Virtual power plant is a system that manages and dispatches distributed energy through information technology and intelligent equipment. Although it is characterized by virtuality, its role is really worthwhile." Jin Yulong takes a large-scale commercial complex as an example. During the peak hours of power consumption in summer, the virtual power plant controller can realize minute-level or second-level remote control, and the temperature of the central air conditioner can be raised by 2~3 degrees Celsius, which can effectively reduce the peak load and ensure the safe supply of power.
"If we can aggregate more buildings and factories, we can better release the potential of existing electricity and ensure the safety of the power grid without building new power plants." Jin Yulong said that at present, the team has basically formed a set of relatively mature virtual power plant solutions, and related achievements have been demonstrated and applied in Jiangsu, Shanxi, Ningxia and other places.
Dedicated to the tide of the times of self-reliance and self-improvement in science and technology, Jin Yulong really felt the message from the Supreme Leader General Secretary "Take ‘ Do one thing in a lifetime ’ Persistence, tackling high-tech problems and achieving a valuable life ". On the afternoon of July 6, in the intelligent manufacturing production area of Nanrui Group, the general secretary asked: "Are you satisfied with working here?" In the unanimous answer, "Satisfied!" in Jinyu Longkou. From the heart. It is understood that as a leader in the young scientific research group, he got the equity incentive last year.
"Scientific research is an endless long-distance running, which requires both ‘ Do one thing in a lifetime ’ Persistence, but also through the talent incentive policy to let the scientific research team ‘ Run one stick after another ’ 。” Zhang Yan, deputy director of the human resources department of Nanrui Group, said that they are speeding up the establishment of a capability evaluation system and a performance appraisal system oriented to innovative value, ability and contribution, and taking the lead in creating a multi-medium and long-term incentive "experimental field", thus forming a situation in which young talents are competing with each other.
Nowadays, young talents have become a pillar here, and group-level experts under 40 account for more than 65%. Zhang Yan introduced that among the winners of Nanrui Group’s science and technology awards in 2020, the proportion under 40 years old exceeded 60%; Among the "333 High-level Talents Training Objects" selected in Jiangsu Province in 2021, youth accounted for more than 20%; In the past two years, there were 9 candidates selected for the Young Talents Promotion Project of State Grid Corporation and the Young Talents Promotion Project of China Electrical Engineering Society, with young people under 35 accounting for more than 40%.
I personally listened to the words of the Supreme Leader General Secretary encouraging young R&D personnel, and Huang Guiyuan was deeply touched after 00. He graduated from Nanjing University with a major in software engineering last year, and is currently engaged in the interface visualization of power dispatching system. "R&D is not a rush, I want to be like the general secretary, ‘ Aim high, be down-to-earth, and move forward step by step ’ . I believe that our young people will be able to provoke the beam of rejuvenating the country through science and technology! " He said.
Industrial ambition of gathering potential and strengthening chain
During this inspection tour in Jiangsu, the General Secretary of the Supreme Leader entrusted Jiangsu with "four new" major tasks, one of which was "showing new achievements in strengthening the chain and extending the chain".
In the past half century, Nanrui Group has developed from a unit with less than 100 employees to a modern enterprise with 14,000 employees. Correspondingly, the smart grid industry in Nanjing has grown from scratch to cluster, with more than 1,200 related enterprises in the city, accounting for 80% of the national market, forming a "one valley and two districts" cluster development pattern with Jiangning Smart Grid Industry Valley as the core and Nanjing Economic and Technological Development Zone and Nanjing Jiangbei New District as the two wings.
The national smart grid sees Nanjing, and the Nanjing smart grid sees Jiangning. As early as the "Twelfth Five-Year Plan" period, Jiangning District planned to build a smart grid industrial park of 7 square kilometers. In recent years, it has built 13 state-level technology business incubators and 20 state-level creative spaces, providing an important platform for accelerating the industrialization of new technologies, improving the regional innovation ecology and gathering innovative small and medium-sized enterprises. At present, around Nanrui Group, Jiangning Smart Grid Industry Valley has gathered more than 280 affiliated enterprises, covering nine key links in the industrial chain.
"Our main product is power equipment, which is a very critical part of the industrial chain." Huanyu Group (Nanjing) Co., Ltd. settled in Jiangning Binjiang Economic Development Zone in 2009. Fan Jianlun, vice president of the company, said that the company has cooperated with Nanrui Group, Guodian Nanzi, Jinzhi Technology and other companies in Jiangning. "Undoubtedly, a sound local industrial chain has greatly helped our business development."

Jiangsu Hengan Energy Storage Technology Co., Ltd. just settled in Jiangning Development Zone last year. Here, enterprises have found a way from scientific research and development to industrial application. "The process of a project from research and development to mass production is not easy." In the view of Duan Huiyuan, the general manager of the company, the team has been engaged in the research of zinc-bromine flow battery for 17 years and entered the industrialization stage. "If we rely solely on our own strength, it will take a lot of time and capital costs."
Duan Huiyuan introduced that when building a new automated production line, they found local equipment provided by Copilon, and Eston provided robots for assembly of production components for the production line. They also sought the research team of Southeast University to jointly solve the problem of improving battery conversion efficiency, and also discussed technical cooperation with Nanrui Group. When they learned that a cooperative enterprise was developing photovoltaic power generation business, they changed from "customers" to "suppliers" to design energy storage power stations for them.
"Our first production line took a year and a half from design to commissioning. The new production line here is expected to complete equipment production, installation and commissioning in half a year, and it will be put into production around the Spring Festival next year. " Duan Huiyuan said frankly that the local mature industrial chain "ecological circle" has greatly accelerated the pace of enterprise development.
"We have implemented regional dislocation development and continuously optimized the industrial layout. The planned output value of smart grid industry has increased from 67.6 billion yuan in 2018 to 122.7 billion yuan in 2022, with a cumulative increase of 69.8%." The relevant person in charge of Jiangning District Bureau of Industry and Information Technology introduced that Jiangning Development Zone promotes the construction of smart grid industry valley around high quality, and builds the core area of smart grid high-end equipment industry and the source of original technology; Binjiang development zone takes advantage of port logistics and modern equipment manufacturing industry, focusing on introducing equipment manufacturing projects related to the shortcomings of the industrial chain; Other parks and street industrial concentration areas, combined with regional reality, guide the transformation and entrepreneurship of scientific and technological achievements related to smart grid industry.
More than a month ago, the smart grid industry multiplication action plan of Jiangning Development Zone was released, the second phase project of Nanrui Jibao Intelligent Electrical Equipment Industrial Park started, and the project of Sunshine Power Nanjing R&D Center was signed and settled; More than two months ago, Nangang’s user-side energy storage power station, known as the "super-large charging treasure", was launched in Jiangbei New District. The industrial layout is steady, major projects are stepped up, and a 500 billion-level smart grid industrial cluster is built. Nanjing is full of horsepower and is determined to win.
