"2021 carbon peak carbon neutralization Yantai forum" was held in Yantai City, Shandong Province from October 19 to 21. At the "sub Forum on integrated smart energy" held on October 20, the guests had an in-depth discussion on the hot spots and pain points of the current development of integrated smart energy, and shared new ideas, new models and new schemes for the development of integrated smart energy.

       Sun Yaowei, chairman of the energy investment committee of China Investment Association and former inspector of the information center of the national energy administration, analyzed the new characteristics of the development of the power industry. The typical characteristics of the new power system are high proportion of new energy, high elastic power grid structure and decentralized supply. He said that under the new scenario, the development of comprehensive smart energy is the general trend, and the electrification, high efficiency, low-carbon, digital and zero carbon industries of power system will accelerate their development.

       Qi Yue, vice president and chief engineer of the comprehensive Smart Energy Professional Committee of China Power Technology Market Association, said that the comprehensive smart energy will become an important carrier and foundation of the new power system with new energy as the main body. It is also a strategic choice for the realization of the new energy security strategy and carbon neutralization goal, and will play a key role in energy activities and the process of carbon neutralization of the whole society.

       Wang Zhigang, general manager and Deputy Secretary of the Party committee of CNNC Huineng Co., Ltd., believes that comprehensive smart energy can realize horizontal cooling, heating, water and gas and vertical network source load storage control, and provide integrated system solutions for the coordination and interaction between multiple energy supply links. The development of comprehensive smart energy industry should move closer to the direction of "source network load storage multi energy coupling".

       Zhao Rui, deputy general manager of digital intelligence technology branch of State Power Investment Comprehensive Intelligent Energy Technology Co., Ltd., introduced the technical system and advantageous functions of Tianshu 1 intelligent energy brain independently developed by state power investment group, as well as the core services provided to project development units, energy operation and maintenance units and energy service units, And shared the successful practice of tianshu-1 in the typical scenario of the integrated intelligent energy platform.

       Zeng Bo, deputy director and associate professor of transmission and Distribution System Research Institute of North China Electric Power University, pointed out that under the goal of carbon neutralization, promoting the energy revolution and building a new power system still face many challenges in the fields of energy production, consumption, technology and system. Scientific planning is the basis for building a comprehensive intelligent energy system.

       During the same period of the meeting, Hu Jun, party secretary and President of CNNC Tongfang Co., Ltd., introduced the potential and cases of smart energy in the construction of low-carbon cities. Li yanpo, deputy general manager of China Nuclear Power Group Xinhua hydropower Co., Ltd., expounded the practical significance of enabling carbon neutralization goal with comprehensive smart energy. Wang Changshan, deputy director of the comprehensive smart energy center of the state power investment group comprehensive Smart Energy Technology Co., Ltd., shared the good practice of the state power investment comprehensive smart energy. Li Zhenming, a professor level senior engineer at the Institute of energy storage and new electrical technology, Chinese Academy of Electric Power Sciences, introduced the cutting-edge technology of comprehensive intelligent energy and the idea and practice of multi class energy Internet mixed transmission technology. Meng Wei, deputy chief engineer of Suzhou Thermal Power Research Institute of China Guangdong Nuclear Power Group, shared the emerging technology to improve the performance of nuclear power operation - the research on key technologies for the reliability of nuclear power cold source.

       Participating experts agreed that vigorously developing comprehensive smart energy is an important part of building a clean, low-carbon, safe and efficient energy system and a new power system dominated by new energy. Taking the carbon neutralization goal as an opportunity, comprehensive smart energy will drive into the fast lane of development.
