President Xi Jinping pointed out in his speech at the opening ceremony of the Group of Twenty Business Summit (B20 Summit, European-style cable joints) yesterday that China has set innovative growth methods as the focus of the Hangzhou Summit and promoted the formulation of the "G20 Innovation Growth Blueprint." , The purpose is to drive innovation, vitality to reform, grasp the historic opportunities of innovation, new technological revolution and industrial transformation, and the digital economy to enhance the medium and long-term growth potential of the world economy.
"Our innovation is to develop the world's most advanced UHV transmission technology, which is a long-distance, large-capacity, and low-loss transmission technology." Shu Yinbiao told reporters.
According to reports, more than 75% of my country's energy resources are in the north and west, and the load centers are mainly in the middle and east, two to three thousand kilometers apart. UHV transmission technology can directly send energy from the west to the east. According to the plan of State Grid, the scale of power transmission from west to east during the "13th Five-Year Plan" period will reach more than 300 million kilowatts.
UHV transmission technology has been successfully developed and applied in China, which has solved the problem of domestic energy imbalance, and also provided a realistic alternative technical solution for the development and delivery of large-scale renewable energy bases around the world in the future And operating experience, Shu Yinbiao said.
There are about ten interconnected lines between the State Grid and neighboring countries, and the annual transaction power is about 20 billion kWh. Shu Yinbiao said that State Grid actively responded to the initiative of President Xi Jinping at the United Nations Development Summit on September 26 last year to "discuss building a global energy Internet to meet global electricity demand in a clean and green way." The global energy Internet is broader and broader. The interconnection of power grids and the replacement of fossil energy by clean energy are the general direction of energy development.
Among the proposals submitted by the B20 to the G20 this time, it is specifically mentioned that the Global Infrastructure Interconnection Alliance should explore the potential impact and feasibility of establishing new industries or regional projects, including the Global Energy Internet (lightning arrester manufacturers).
"In the future, some new energy sources, such as the Sahara Desert or some large-scale wind power bases, can be developed after the energy storage technology can be commercialized and used UHV technology to transport thousands of kilometers away to solve the problem of new energy development. "Shu Yinbiao said
In the interview, Shu Yinbiao also mentioned two world-leading technologies of State Grid, one is security control technology. According to reports, China’s power grid is currently the safest in the world and depends on an efficient power system and independent knowledge. Power grid control and protection technology; the other is the largest scale of new energy access. China’s renewable energy accounts for 35%. The installed capacity of new energy power generation is about to exceed 200 million kilowatts, making it the largest scale of new energy access in the world. Power grid, which mainly relies on smart grid technology.
The fundamental driving force to promote the development of the world economy is innovation. Shu Yinbiao said that facing the general trend of energy transition and supporting the development of low-carbon economy, State Grid will further study more advanced technologies, including energy storage technology, electric vehicles, and grid-friendly new technologies. Energy power generation technology, etc.
