"The innovation of the national grid is to develop the most advanced UHV transmission technology in the world and is a long-distance, high-capacity and low-loss transmission technology. Energy represented by new energy sources, smart grids, large-scale modern energy storage technologies and electric vehicle development The revolution in the field may give rise to a new round of industrial revolution. "Recently, Shu Yinbiao, chairman of China State Grid Corporation, said in an interview with reporters during the B20 summit. According to reports, more than 75% of China's energy resources are in the northern part of western China, while the load center is mainly in the eastern part of the country, two or three kilometers apart. Through the UHV transmission technology, western energy can be sent directly to the east. According to the plan of the State Grid, the scale of the transmission from west to east during the 13th Five-Year Plan will reach over 300 million kilowatts. EHV transmission technology has been successfully developed and applied in China, solving the problem of domestic energy imbalance and providing realistic options for the future development and delivery of large-scale renewable energy bases in the world. And running experience, Shu Yin Biao said. There are about 10 interconnected lines between the State Grid and the neighboring countries, with an annual transaction volume of about 20 billion kwh. Shu Yinbiao said that SGCC responded positively to the proposal put forward by President Xi Jinping at the UN Development Summit on September 26 last year, "exploring the construction of a global energy Internet to meet the global electricity needs in a clean and green manner." The global energy Internet is wider and wider Power grid interconnection, clean energy to replace fossil energy is the general direction of energy development. In the B20's proposal to the G20, it was mentioned that the Global Alliance for Infrastructure and Connectivity should explore the potential impact and feasibility of establishing new industries or regional projects, including the Global Energy Internet (GEI). "In the future, some new energy sources, such as the Sahara or some large-scale wind power bases, can be developed if commercialized energy storage technologies can be used to transport UHV technology thousands of kilometers away to solve new energy development problems "Shu Yin Biao said. In an interview, Shu Yinbiao also mentioned two of the world's leading technologies of the State Grid, one of which is security control technology. According to reports, China's power grid is currently the world's highest level of security and depends on an efficient power system and independent intellectual property Of the grid control and protection technology; the other is the largest access to new energy sources, China's renewable energy to achieve 35% of the proportion of new energy power generation installed capacity is about to break 200 million kilowatts, is the world's largest new energy access The grid, which relies mainly on smart grid technology. Shu Yinbiao said that facing the general trend of energy transformation and supporting the development of a low-carbon economy, the State Grid needs to further study more advanced technologies, including energy storage technologies, electric vehicles and grid-friendly new technologies. Energy generation technology.
