What changes will occur in the grid model, which is the main source of energy transmission, in the transformation of old energy production and consumption patterns and the optimization of energy resources in larger areas? What new transmission methods and control methods will be adopted in the future grid? Which new science and technology can meet the requirements for safe, efficient, and intelligent operation of power grids under new energy supply and consumption patterns? These problems are one of the most concerned issues of current experts in the energy and power fields. Many countries and institutions in the world have started relevant research and are committed to the research and development of the roadmap for the development of power grid and power grid technology. In order to extensively explore the various challenges faced by the development of China's power grids in the context of the new energy revolution, to look into future grid models and development trends, to explore the key factors and scientific issues affecting the development of power grids, and to evaluate the application of new technologies in the development of power grids, Xiangshan Science From September 27 to 29, 2012, the conference was held in Beijing to discuss the theme of “Future Grid and Grid Technology Development Forecast and Countermeasuresâ€. Prof. Zhou Xiaoxin from China Electric Power Research Institute, Prof. Cheng Shijie from Huazhong University of Science and Technology, Professor Guo Jianbo from China Electric Power Research Institute, Prof. Liang Xiaodong from the Department of Electrical Engineering of Tsinghua University, and Prof. Xiao Liye from the Institute of Electrical Engineering of the Chinese Academy of Sciences as Executive Chairman of the conference. More than 50 experts and scholars in various disciplines and fields. Invited to participate in the meeting, the participating experts centered around (1) the future grid model and power system; (2) new transmission methods and transmission technologies; (3) superconductivity and advanced energy storage technologies; and (4) new materials, devices, and power transmission and transformation Equipment and other central issues are discussed in depth. Prof. Zhou Xiaoxin made a report commenting on the topic of “Prospects for the future development of power grid and power grid technologyâ€, pointing out that the main driving force of the new energy revolution is the shortage of fossil energy and the threat of global climate change, and its mission is to build new energy power transmission and distribution. Network, flexible and efficient energy network, energy power and information integrated service system and safe and reliable power supply system. From the perspective of development prospects, if the per capita electricity consumption is estimated to be 8000 kWh and 1.5 billion people, China's total installed capacity in the future (2020 to 2050) will be 3.2 billion kW, or 2.1 kW per capita, and the demand for electricity transmission will reach 710 million kW. China's future third-generation grid model will be a combination of large backbone power supplies and distributed power supplies; large-scale transmission backbone networks will be combined with local transmission and distribution networks and micro-grids; clean energy power will account for more than 50%. From 2020 to 2030, the shape of China's power grid should be a complex grid of super-large-scale super/UHV AC/DC hybrids. From 2030 to 2050, China will build a flexible, controllable, low-loss, high-reliability trans-regional super power transmission network nationwide. Ten key technologies that have a significant impact on power grid development are large-scale new energy and renewable energy friendly power access technologies (including distributed), large-capacity transmission technologies, advanced sensor network technologies, power communication and information technology, Large-capacity energy storage technologies, new types of power electronic devices and application technologies, advanced power grid dispatch, control and protection technologies, advanced computational simulation technologies for power systems, intelligent (active) distribution networks and micro-grid technologies, and smart electricity technologies. Experts at the meeting held a lively discussion on the per capita electricity consumption of 8000 kWh, and proposed to radically change the lifestyle and consumption perspectives, adopt a more energy-saving and environmentally-friendly life mode, and the per capita electricity consumption should be controlled, which is much less than this value. According to many years of experience in power planning, China's "repair-style" consumption will lead to a substantial increase in per capita electricity consumption, even without using 2050 will exceed the 8000kWh index. Everyone agrees that per capita electricity consumption indicators should be combined with social science experts and electric power experts to conduct in-depth studies. The second hot issue is related to the development ratio of coal-fired power and renewable energy. Some experts believe that the 40% coal-to-electricity ratio is not feasible, and the current development scale of wind power, photovoltaic, and nuclear power is slower than expected, and the coal-fired power ratio should be Considering 50% or even 60% is more practical. The third topic of discussion is about the scale of transmission. Some experts pointed out that: 710 million transmission capacity, according to the existing transmission technology to estimate, requires more than 100 transmission channels, but the resource and environmental constraints make it impossible to build so many transmission channels, so there must be a change in the scale of development, change Development model and the process of seeking new technological revolutions. I.

The gradual replacement of fossil fuels with renewable energy, and the realization of clean energy such as renewable energy and nuclear energy, account for a greater share of primary energy production and consumption. The establishment of a sustainable energy system is the main goal of this new energy revolution. 2. Under the conditions of the new energy revolution, the importance of the power grid has become increasingly prominent. The power grid will become a large-scale new energy power transmission and distribution network; it will integrate organically with distributed power sources, energy storage devices, and comprehensive and efficient energy use systems to become a flexible and efficient smart energy network; with high reliability of power supply, basic elimination of large Area outage risk; Widely integrated with information and communication systems, complete energy, electricity, information integrated service system.
