At the end of September, Chinese President Xi Jinping announced at the United Nations Development Summit in United Nations Headquarters in New York: China proposed to explore the construction of a global energy Internet to promote global electricity demand in a clean and green manner. Experts believe that this initiative has positive practical significance for promoting the sustainable development of energy and environment in human society. "The so-called energy Internet means that the energy of diversified production can be easily and quickly transferred to places with higher demand," Joanna &dot, director of the Grantham Institute for climate change at the Imperial College London, UK, said to the new China correspondent in E - mail. "Solar, wind and ocean can have changes and intermittent characteristics, but the energy Internet will allow the integration of decentralized and smaller renewable energy producers." In June this year, Haig took part in a European Climate Forum and was impressed by the concept of global energy Internet introduced by China's national Power Grid Corp. She said that President Xi proposed to build the global energy Internet and support the efforts of the international community to cut carbon emissions. "The news is wonderful." "China has a huge technical capacity, and if China plans to start and support the necessary development of the global energy Internet, I am sure that the great advantage of the global energy Internet will become more and more realistic, and the world is getting closer to a cleaner and greener future," Hague said. It is worth noting that the energy Internet is still not widely accepted. In the United States, Huang Qin, a Chinese professor at North Carolina State University and the author of the best-selling book "the third industrial revolution", and Jeremy &dot, an economist, and reiking, have also put forward the concept of energy Internet. Reevin believes that hundreds of millions of people can produce green renewable energy in their homes, offices and factories, and the excess energy can be shared with others, just as we share information on the Internet, that is, the energy Internet. Huang Qin put forward the concept of energy Internet, more emphasis on each household to participate in the electricity market for real time trading, to transform the closed electric power market for a hundred years into a modern commercial development model which is generally competitive with the Internet. Unlike reevin and Huang Qin, the global energy Internet proposed by the China national grid is more focused on transmission and use. It refers to the backbone grid (channel) using UHV power grid to transport the electricity generated by clean energy, and the strong smart grid, which is interconnected and widely distributed worldwide. At present, the global distribution of new energy is very uneven, such as the abundant solar energy near the equator, rich wind energy near the north pole, and the global energy Internet will connect the above "one pole and one" and the large energy base of all continents to transport the electricity generated by renewable energy, such as wind energy, solar energy and marine energy, to various types of use. Household. At a recent symposium held in New York, New York, Liu Zhenya, chairman of China's national Power Grid Corp, said the key period to build the global energy Internet in the next few decades was divided into three stages: domestic interconnection, intercontinental interconnection and intercontinental interconnection. By 2050, a global energy Internet was built to form clean energy. The dominant energy pattern. Chinese Power Grid Corp personages described to journalists a map of the energy Internet: linked to Europe and Asia on the same continental plate, Asia and North America connected by the Bering Strait, South America and North America connected, North Africa connected to Europe through the Mediterranean, or via the Gibraltar gorge or West Asia, and Egypt and Egypt in East Africa. Ethiopia is connected to Asia, and Southeast Asia and Australia connect through submarine cables. "This is a great idea," Hague said. "Early studies have shown that interconnectivity at least in the continent is feasible, but it needs a thorough solution to the technology of transmission and intelligent control." In an interview with Xinhua news agency, Huang Qin said that the global energy Internet proposed by China's national grid is somewhat similar to that of high-speed rail, connecting all major regions. The first thing to do is to determine where there is a large demand for power transmission, followed by many political and policy aspects, "may not be a simple technical problem." For example, there are regulatory problems in the US power grid, and not every company can enter it.

For the various concepts of the energy Internet, he thinks there is complementarity and there is actually no conflict. China's State Grid is ahead of the world in UHV, and can play its advantage by using UHV to build an energy Internet backbone network. The concept of Huang Qin focuses on the user side. The goal is that every user plays a more important role in the transmission, distribution and trading of electricity. Looking ahead to the future of the energy Internet, Huang Qin said that energy is now seen as a necessity, but it has not yet been seen as an engine of economic growth. It is hoped that the energy Internet can release more powerful development power than the information internet, so that everyone can benefit from it.
