The development and construction of smart grids is a systematic engineering project that involves many disciplines and industries. At the same time, there is no readily available experience for smart grids to learn from, and they must be based on China's national conditions and adhere to independent innovation. Therefore, a strong smart grid will greatly improve the overall technological level of China's power industry and related industries, enhance the system innovation ability of the power industry and related industries, drive the overall optimization and upgrading of the power industry and related industries, promote the rapid development of high-tech and emerging technology industries, play an important role in promoting economic and social coordination and sustainable development, and achieve energy conservation and emission reduction in China, Ensuring national energy security, leading and promoting knowledge and technological innovation, is of great significance.

Promote the optimization and upgrading of the energy industry

There is an inherent deficiency in the distribution of primary energy resources in China, which is contrary to the layout of productivity. Due to the high concentration of coal resources in the western and northern regions of China, with an average railway transportation distance of over 1200 kilometers (the longest transportation distance exceeding 2300 kilometers), coal sold to the southeast coastal areas no longer has a competitive advantage in price compared to imported coal. In addition, there are still problems with extensive development, simple processing, high pollution and high consumption in coal producing areas in China, which makes the ecological environment in the western and northern regions more fragile.

By building a strong smart grid, the coal to electricity conversion ratio in coal producing areas can be improved, the coal development and utilization industry chain can be extended, regional economic coordinated development can be promoted, and its resource advantages can be effectively transformed into economic advantages, driving local economic development. Especially, it can promote the optimization of the local energy industry structure and, on the basis of economic development, attempt a sustainable development model that combines resource development and ecological reconstruction. For example, promoting the deep processing and comprehensive utilization of low-grade coal, accelerating ecological reconstruction and land reclamation in mining areas, increasing the management and utilization of gas and coking gas, and promoting the comprehensive utilization and management of abandoned resources in coal mine production.

Smart grids can directly drive primary energy output, increase production capacity, and promote industrial structure optimization and upgrading, while also reducing environmental pollution. Research has shown that through overall planning and increasing the proportion of power transmission, the central and eastern regions can reduce sulfur dioxide emissions by 550000 tons/year and reduce national environmental losses by 4.48 billion yuan/year by 2020.

Boosting the development of clean energy industry

China's renewable energy resources have the characteristics of large scale, concentrated distribution, and being far from the load center, and must follow the development path of centralized development, large-scale export, and large-scale consumption. With the increasing proportion of clean energy in the power structure, the bottleneck of consuming large-scale clean energy is becoming increasingly prominent; On the other hand, distributed power generation and energy storage systems will take shape, but the existing power grid is not yet fully adapted. The randomness and intermittency characteristics of wind and solar power generation require a significant improvement in the fast, stable, and reliable energy exchange and transmission capabilities of the power grid, as well as the level of safe and stable operation. At the same time, strict requirements are put forward for power grid operation control, dispatch command, low consumption and efficient operation.

The ability of a strong smart grid to access, consume, and stably transmit clean energy on a large scale will continue to improve, and the ability to access and consume distributed energy systems will also continue to improve. This will significantly increase the scale of renewable energy, greatly promote the demand for clean energy and new energy power generation equipment, distributed energy and power generation equipment, and various grid connected control and protection equipment, and drive energy storage The rapid development of the power electronic components and systems industry.

In addition, through the smart grid platform, complementary and balanced utilization of different energy sources can be achieved, their availability and efficiency can be improved, clean energy efficient utilization and scientific development can be promoted, energy comprehensive utilization efficiency can be improved, and energy conservation and emission reduction can be promoted.

Enhance innovation in the equipment industry system

A strong smart grid requires the power grid to have a strong architecture, agile response, agile control, environmentally friendly operation, efficient operation, and economic operation, which provides significant development space and huge challenges for the power equipment industry.

With the promotion of strong smart grid construction, the benefiting industries will cover all aspects of the power equipment industry. The development of the power grid will drive the systematic innovation and upgrading of the power equipment manufacturing industry, and accelerate the widespread application of new materials and environmental protection technologies. The demand for "intelligence" in the power grid will put forward higher requirements for the intelligence of traditional power equipment, thereby driving the traditional power equipment manufacturing industry to optimize industrial structure, improve product informatization, accelerate product transformation and upgrading, and comprehensively improve the comprehensive technical level of China's power equipment manufacturing industry. In addition, as an important component of a strong smart grid, intelligent components, sensors, etc. will also be further upgraded.

The "intelligentization" process of a strong smart grid and the "integration" process of power flow, information flow, and business flow will greatly promote the integration and technological integration of the power industry and information technology industry. Therefore, in the construction process of smart grids, the demand for the information and communication industry will reach an unprecedented level, which will become an emerging growth point driving the development and innovation of the information and communication industry.

Strengthening the weak points of basic industries

The construction of a strong smart grid will play a role in reinforcing, promoting, and breaking through the weak points in some basic industries in China.

Technologies such as chips, communication, and basic materials are the foundation and focus of achieving intelligence in the power grid, and are also the core industries that ensure the safety and reliability of China's future smart grid. With the advancement of the construction of a strong smart grid, new technological challenges have been posed to related industries. For related industries, this is a significant opportunity to achieve core technology autonomy, key equipment localization, product preparation industrialization, and industrial system systematization, as well as a rare opportunity to break foreign technological monopolies. Moreover, the strong smart grid has a positive mutual driving and promoting relationship with it: on the one hand, the demand for related industries in the strong smart grid involves various aspects, and through increasingly high technical requirements, it improves its technical level and promotes industrial development; On the other hand, the improvement of technological level in related industries will promote the development of strong smart grids and provide them with more flexible intelligent control methods.

A strong smart grid has put forward higher requirements for controllability and adjustability, which can make the application of power electronic devices and equipment in power systems a future technological trend, leading another revolution in China's power electronic technology field and semiconductor material technology field.

Promote environmental protection, energy conservation, and livelihood industries

The smart grid is a friendly, interactive, transparent, and open "flexible" power grid. Electricity, as the main way of using energy as a social terminal, will become an important symbol of the future well-off life of the people. Therefore, smart home appliances, smart electricity terminals, and power fiber optic households will become important components of future environmental protection, low consumption, and efficient living. The strong smart grid will not only provide a solid foundation for its development and implementation, but also effectively promote the leapfrog development and transformation innovation of China's home appliances, information communication, network and supporting industries; At the same time, it will drive the development of China's energy efficiency management industry and promote energy conservation and consumption reduction throughout society.

In order to alleviate the increasingly scarce pressure of fossil energy, a strong smart grid will fully increase the proportion of renewable energy in the power structure, supporting the construction of charging facilities suitable for various types of electric or hybrid vehicles, laying the foundation for the formation of a large-scale energy-saving, low consumption, and low emission transportation network, and extending to drive the rapid development of energy storage, power electronics, and control technology industries.

Improving the comprehensive social and economic benefits

At present, smart grids are basically on the same starting line both domestically and internationally, which not only provides important strategic opportunities for China to achieve leapfrog development of related industries and reach world advanced levels, but also challenges that China must face to seize the strategic heights of future energy conservation, environmental protection, and economic development. To achieve coordinated, sustainable, and healthy development in China's economy and society, it is necessary to transform the development model and approach. The development of smart grids will drive the optimization, upgrading, and transformation of related industries, drive high-quality and creative employment, create new development growth points with good social and economic benefits, and promote the awareness of energy conservation, environmental protection, and sustainable development of the entire society.

Firstly, the demand for strong smart grid construction itself will have a huge market effect, directly promoting the improvement of related industry scale, energy efficiency, and efficiency, and driving the innovative development of upstream and downstream related industries. Secondly, the smart grid will provide society with higher quality, environmentally friendly, reliable, and efficient electricity, reduce resource consumption, improve investment cost-effectiveness in various industries, and optimize industrial upgrading. At the same time, smart grids can enhance the enthusiasm, initiative, and participation of the public in energy conservation and environmental protection. In addition, the smart grid itself can also generate huge economic benefits. If China's peak electricity consumption can be reduced by 5%, it will save hundreds of billions of yuan within 20 years.

A strong smart grid is an economically efficient, clean and environmentally friendly modern power grid, which is conducive to the rational planning and implementation of macroeconomic policies and economic leverage, to encourage the development of energy-saving and emission reduction industries, eliminate outdated, high pollution and high energy consuming industries, fundamentally promote resource conservation and rational utilization, and reduce the comprehensive cost of social and economic development. At the same time, the smart grid will create an outstanding number of job positions and job opportunities, with the highest proportion being "green collar jobs" and "green collar job opportunities".

I believe that with the advancement of the construction of a strong smart grid, it will inevitably drive the upgrading and innovation of a series of industries, promote the transformation from "Made in China" to "Created in China", and promote the leapfrog development of power and related industries; At the same time, it will also bring radiation and driving effects to surrounding industries such as infrastructure and livelihood services.
