Superconducting power technology will change China's traditional power grid model and promote new energy transformation

It is reported that in the future, China will still maintain the pattern of national networking, and "west-to-east power transmission, north-south power transmission" will be China's basic national demand
.
Superconducting power technology has significant advantages
in improving the security and stability of the power grid and power quality, improving the large-capacity long-distance transmission capacity, reducing the loss of the power grid and reducing the land used for power equipment.
If it is widely used in the power grid, it is of great significance to promote the transformation of
new energy.

Superconducting power technology will usher in the third stage of development, the core of which is to realize the practical application of superconducting technology, but it is necessary to focus on the physical mechanism of high-temperature superconductivity and increase the critical temperature of high-temperature superconductors to make major breakthroughs
.
The cross-regional interconnection of the national power grid will still be the basic demand of China, and the new transmission technology of the DC transmission grid based on superconducting transmission has great advantages in principle, due to the large loss of conventional transmission technology, if a major breakthrough in superconducting physics and materials will be of great significance
.

Superconducting power technology is a completely new paradigm that will revolutionize the traditional grid model
.
However, the development of superconducting power technology requires long-term efforts, in addition to increasing the critical temperature of superconductors, new breakthroughs
need to be made in superconducting materials, cryogenic engineering and other aspects.
At present, the direction that the power grid has special needs and is difficult to solve with conventional technology can be selected as the entry point, such as short-distance large-capacity power transmission of transmission
lines across rivers and tunnels.
Since the development of power grids requires the integration of multiple technologies, attention should also be paid to the organic integration and complementarity
of superconducting power technology and other technologies.
The composite application of superconducting energy storage systems and various energy storage systems is of great significance to promote the utilization of
renewable energy.

China should set up a "superconducting power technology action plan", strengthen the overall design of superconducting power technology and formulate a short-, medium- and long-term development strategy roadmap, highlighting the goal-driven orientation
.
Superconducting power technology will become one of the important research and development directions of
China's future power grid technology.
