President Xi Jinping pointed out in his speech at the opening ceremony of the G20 Business Summit (B20 Summit, European Cable Joint) yesterday that China has set innovative growth methods as a key topic of the Hangzhou Summit and promoted the formulation of the "G20 Blueprint for Innovative Growth". The purpose is to seek power from innovation and vitality from reform, seize the historic opportunities of innovation, new technological revolution, industrial transformation, and the digital economy, and enhance the medium- and long-term growth potential of the world economy.
“Our innovation is to develop the world’s most advanced ultra-high voltage transmission technology, which is 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 northern part of the west, while the load centers are mainly in the central and eastern parts, two to three thousand kilometers apart. Energy from the west can be directly sent to the east through UHV transmission technology. According to the State Grid’s plan, the scale of west-to-east power transmission 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, solving the problem of domestic energy imbalance and providing realistic alternative technical solutions and operational experience for the future development and delivery of large-scale renewable energy bases around the world, Shu Yinbiao said.
There are about ten interconnected lines between the State Grid and neighboring countries, and the annual transaction volume of electricity is about 20 billion kilowatt hours. Shu Yinbiao said that State Grid actively responded to the initiative put forward by President Xi Jinping at the United Nations Development Summit on September 26 last year to "explore the construction of a global energy Internet to meet global power demand in a clean and green way." The global energy Internet is a wider and wider range of power grid interconnection, and the replacement of fossil energy with clean energy is the general direction of energy development.
Among the recommendations submitted by the B20 to the G20, it was specifically mentioned that the Global Infrastructure Connectivity 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 wind power bases, if energy storage technology can be commercialized, they can be developed and transported thousands of kilometers away using ultra-high voltage technology to solve the problem of new energy development." Shu Yinbiao said.
During the interview, Shu Yinbiao also mentioned two world-leading technologies of State Grid. One is safety control technology. According to reports, China's power grid is currently the safest in the world, relying on an efficient power system and grid control and protection technology with independent intellectual property rights. The other is the largest scale of new energy access. China's renewable energy has achieved a proportion of 35%. The installed capacity of new energy power generation is about to exceed 200 million kilowatts. It is the power grid with the largest scale of new energy access in the world. This is mainly relying on smart grid technology.
The fundamental driving force for world economic development is innovation. Shu Yinbiao said that in the face of the general trend of energy transformation and supporting the development of a low-carbon economy, State Grid must further research more advanced technologies, including energy storage technology, electric vehicles, and grid-friendly new energy power generation technology.
