The global energy Internet will help the three major technological innovations to make major breakthroughs

Building and promoting the development of the global energy Internet will drive major breakthroughs
in UHV, smart grid and new energy technology innovation.

The first is to promote the development of transmission technology to a higher level
.
With the acceleration of the construction of intercontinental interconnected large power grids in the future, the UHV transmission technology will be promoted to develop in the direction of larger capacity and higher voltage level, with a transmission distance of more than 3,000 kilometers and a transmission capacity of more than 10 million kilowatts, with a larger range of resource optimization allocation capabilities; Secondly, the development of large-scale new energy bases in offshore and polar regions plays an important role in promoting the development of flexible HVDC transmission technology, which will further improve the voltage level and transmission capacity of flexible HVDC transmission, and the voltage level is expected to reach ±500kV~±800kV, and the capacity will increase to 300~5 million kilowatts, which will play an important role
in supporting the grid connection and transmission of offshore wind power and large-scale polar new energy bases 。 At the same time, it will put forward higher requirements for the safe operation control technology of large power grids, further improve the level of large-scale AC and DC power grid simulation modeling, safety control protection technology and automation technology, and ensure the safe and stable operation of power grids and reliable global power supply
under the condition of high proportion of new energy access.

The second is to promote breakthroughs
in new energy power generation technology.
The new energy base is an important energy source for the global energy Internet, and it is very urgent
to build a global energy Internet and accelerate the innovation and development of new energy technology.
At present, 4-6MW wind turbines have been operated on a large scale, 8MW wind turbine prototypes have entered the installation and testing stage, European and American complete turbine design companies have entered the 10MW class design stage, and began to explore and study the 20MW model scheme, the future wind turbines will develop towards large-capacity and high-parameter technology; At present, the maximum power generation efficiency of crystalline silicon and thin-film cells can reach 25% and 20.
8%, and it is expected to further increase to 30% and 25%
in 2030.
At the same time, three generations of solar cell innovative technologies such as perovskite type and lamination will play an important role
in improving efficiency, reducing costs and developing on a large scale.
At the same time, new energy power generation will develop in the direction of considerable, measurable and controllable technology, so as to achieve the overall power generation technical performance of renewable energy power plants to reach the conventional power supply capacity, and truly become the main power source
of power system friendly.

The third is to promote the leapfrog development
of smart grid technology.
Internet technology will open up the cross-integration of power system, information and communication, advanced materials and other fields, comprehensively improve the intelligent and interactive level of the power grid, and enrich and expand the development space
of smart grid.
In the future, based on big data analysis, cloud computing, Internet of Things and other Internet information technologies will be deeply integrated and applied in various fields of the power system, promoting the gradual transformation of the future power system from a single production power supply system to a comprehensive energy service platform, and a new architecture that is user-centered, experience-oriented, and two-way flow of energy flow and information flow will be possible to establish to realize the two-way interaction
between producers and consumers in energy flow and information flow 。 At the same time, in the future, the distribution network will have a reliable and flexible hierarchical and zoning topology, a strong grid structure, and a further improvement in the level of distribution automation, supporting a large number of distributed power sources and energy storage devices "plug and play", and greatly improving the level of development and utilization of
distributed power sources.

The essence of the global energy Internet is "UHV + smart grid + new energy"
.
At present, developed countries such as the United States, Japan and Europe have successively introduced a new energy development strategy that reflects the national will, and carried out a strategic layout for energy and power technology innovation in the next decade or even longer, and large grid technology, smart grid technology, and new energy technology have become the key content
of scientific and technological innovation and deployment in various countries.

The global energy Internet will drive the upgrading of emerging industries and is a powerful engine
for promoting economic and social development.
Energy and power development is an important material guarantee
for a country's economic growth and social development.
Relying on the global energy Internet, accelerate the innovation of new energy power generation technology and large-capacity transmission technology, enable large-scale and efficient development and utilization of various new energy sources, and achieve a larger range of optimal allocation through the large power grid, ensure the clean and sustainable supply of global energy and electricity, and provide inexhaustible power for economic and social development; At the same time, the deep integration of the global energy Internet with the Internet of Things and the Internet will drive the innovation and development of strategic emerging industries such as new energy, new materials, intelligent manufacturing, and electric vehicles, and have a significant pulling effect
on economic growth, structural adjustment and industrial upgrading.
