On June 4, the Ministry of Science and Technology issued an article to interpret the "12th Five-Year Plan for Special Projects for Major Technology Industrialization of Smart Grids" (hereinafter referred to as "Planning"), stating that the smart grid is to implement new energy strategies and optimize the allocation of energy resources. The important platform for the implementation of smart grid major science and technology industrialization projects is of great significance for the adjustment of energy structure, energy conservation and emission reduction, and response to climate change.

Relevant layouts will be carried out in the six industries. At present, the construction of smart grids worldwide has started, but since the research and development of smart grids is still in its infancy, the national conditions and resource distribution in different countries are different, and the direction and focus of development are not always the same. the same. Specific to China's energy and power development status, it faces two basic realities: First, the lack of energy resources, it is difficult to support the current social and economic development model, and the geographical distribution of energy resources and electricity demand is extremely uneven; Second, climate change The low-carbon socio-economic development model that has spawned has placed imminent pressure on the development of the power system.

In response, the Ministry of Science and Technology pointed out that in order to support the development of smart grids, during the “Twelfth Five-Year Plan” period, China will need to lay out the following industries:

(1) Clean energy generation, smart grid construction will greatly increase the capacity of the grid to accept intermittent clean energy, which is a prerequisite for the further rapid development of clean energy;

(2) Clean energy power generation equipment manufacturing, such as wind power generation, solar power generation, etc.;

(3) New material industries, such as photoelectric conversion materials, energy storage materials, insulating materials, superconducting materials, nanomaterials, etc.;

(4) Power grid equipment manufacturing industries, such as new power electronic devices, transformers, etc.;

(5) Information communication, instrumentation, sensing, software, etc.;

(6) New energy automobile industry. In addition, smart grids also involve consumer electronics such as home appliances.

“In addition to the cooperation of the power transmission and distribution industry, the construction of smart grids also requires the support of many upstream and downstream industries, and has led to the development of many emerging industries.” The relevant responsible person of the Ministry of Science and Technology of the State Grid said earlier.

“Planning” deploys nine key tasks to build a smart grid that can achieve a comprehensive technological leap in all aspects of power generation, power transmission and distribution, power distribution and power grid operation control, and will be advanced through advanced modernization and transmission and distribution capabilities. Highly-convergence of technology, large-scale development and utilization of new energy and renewable energy, comprehensive improvement of the intelligent control level of large-scale power grid operation, improvement of power transmission and power supply capacity, ability to withstand major failures and natural disasters, and improvement of power supply service capability and level To realize the leap-forward development of China's power grid. So, what technical support is needed for the construction of smart grid in China?

The Ministry of Science and Technology pointed out that the "Planning" has deployed nine key tasks, including large-scale intermittent new energy grid-connected technology, grid technology supporting the development of electric vehicles, large-scale energy storage systems, intelligent distribution technology, and smart grid smart operation. Integrated demonstration of control technology, intelligent transmission and transformation technologies and equipment, power grid information and communication technology, flexible transmission and transformation technologies and equipment, and smart grid integration. Among them, each key task includes several specific tasks. For example, the intelligent operation and control technology of large power grids needs to study the integrated support of key technologies for smart grid dispatch, multi-level and multi-dimensional coordinated energy-saving optimization and scheduling key technologies.

In addition, the "Planning" also attaches importance to demonstration projects and industry development. 20-30 smart grid technology demonstration projects and 3-5 smart grid integrated demonstration projects will be built to build 5-10 smart grid demonstration cities and 50 smart grids. Demonstration parks, and promote investment in technology and technology, energy, transportation, manufacturing, materials, information, sensing, control and other industries of technological innovation and development.
