Site of the Fifth World Smart Conference Urban Energy Revolution Summit Forum

At the 5th World Intelligence Conference being held in Tianjin, China's first "Carbon Peak, Carbon Neutral" industry alliance co-sponsored by State Grid Tianjin Electric Power Company and Tianjin New Energy Association was unveiled, which provides a platform for energy transformation and upgrading. new ideas. China has previously announced that it will strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. This is a major strategic decision made by China based on the responsibility to promote the building of a community with a shared future for mankind and the inherent requirements of achieving sustainable development. Experts and scholars participating in the World Intelligence Conference believe that accelerating the construction of smart energy will provide a feasible solution for China's low-carbon green development. In this newly established alliance, energy and power-related industry associations and enterprises, energy equipment manufacturers, large-scale energy-using enterprises, scientific research institutions, and design institutes are among them. From the perspective of cooperation path, by coordinating energy enterprises, scientific research institutions and design institutes to achieve technology integration, the efficiency of alliance members in the process of technology research and development, market development, and supporting supply can be effectively improved, and the formation of co-construction, co-governance and shared industries will be promoted. Ecosphere.

In this regard, He Ping, deputy chief engineer and head of the development department of State Grid Tianjin Electric Power Company, believes: "The establishment of the alliance is conducive to promoting the integration and optimization of resources and the improvement of the industrial chain, and to accelerate the transformation and upgrading of energy and serve the local 'dual-carbon' goals. The greatest combined force of energy and electricity.” In practice, Chinese electric power researchers have found that cities are the main body of energy consumption. Zhang Zhigang, deputy general manager of State Grid Corporation of China, revealed that every one percentage point increase in the urbanization rate will drive energy consumption of tens of millions of tons of standard coal. Therefore, to accelerate the transformation of urban energy and provide green, low-carbon and sustainable urban energy solutions, grid intelligence is an important direction.

Zhang Zhigang said that by integrating and applying advanced information and communication technology and energy technology to improve the intelligence level of the power grid, it can not only better meet the needs of large-scale grid connection of new energy, but also effectively support the needs of distributed power, electric vehicles, energy storage and other facilities. It can also promote the coordinated interaction of the source, network, load and storage, improve the efficiency of urban energy resource allocation, and support the large-scale development of new energy. Improving energy efficiency through smart energy is gradually becoming a reality in industrial applications. In FAW FAW BENTELER Auto Parts (Tianjin) Co., Ltd., a large number of intelligent robots not only improve the production efficiency of enterprises, but also bring about the problem of grid load. As long as 79 intelligent robots for automatic welding of auto parts are operated at the same time, a strong inrush current will be formed instantly, causing the voltage to drop synchronously, and it is difficult to ensure the welding accuracy.

Smart energy control systems provide the solution. Once the voltage of the production line in the factory is unstable, the smart energy control system will immediately monitor it, and issue a protection command to the terminal management equipment, and the uninterruptible power supply and other management equipment will immediately activate the protection function to ensure the safe and stable operation of the production line. "After adopting the 'smart energy consumption system', the welding accuracy of the enterprise can be improved by 5%, and the defective product rate can be greatly reduced." Wang Wei, director of the company's equipment department, said that today the company reduces the average number of scraps by about 40 every day, which can save losses every year. more than 1 million yuan.

Yu Yixin, academician of the Chinese Academy of Engineering, admitted that achieving carbon peaking and carbon neutrality requires a high proportion of renewable energy, especially the development of distributed energy, such as wind power, photovoltaics, etc., which can not only save the construction and transportation costs of large power grids, but also The reliability of power supply can be improved. Of course, wind energy and solar energy are facing the problem of periodic instability. The key to solving this problem is to build a new power grid. Among them, source-network-load-storage coordination is the key, and digital empowerment is an important means. "The goal of the smart grid is to generate new technologies and business models like the Internet." Looking ahead, Yu Yixin believes that smart grid technology can not only drive wind power, electric vehicles, photovoltaic power, green energy-saving buildings and smart homes, etc. The upgrade of technology can also drive the technological progress of the smart grid creation platform, and promote the latest research in engineering technology and electronic technology.

Zhao Honglei, deputy director of the Development Planning Department of State Grid Corporation of China, said that the energy revolution and the digital revolution are rapidly converging. In the future, the development idea of the energy Internet is to ensure the green and safe supply of energy, and comprehensively improve the information collection, transmission and processing capabilities through the digital transformation of the power grid. Achieving carbon neutrality goals”.
