I. What is Smart Grid
Smart grid is the intelligentization of power grid, also known as "grid 2.0", which is built on the basis of integrated, high-speed two-way communication network, through the sensing and measurement technology, equipment technology, control methods and decision support system technology application, to achieve the grid's reliability, security, economy, high efficiency, environmentally friendly and safe use. safety of use.
The establishment of Smart Grid is a huge and historic project, and many complex Smart Grid projects are currently underway, but the gap is still huge.
Smart grid is the embodiment of the changes in the development of power and energy industry in today's world, and is an important platform for the implementation of new energy. In the "Internet + +" under the wind, the smart grid will certainly open the door to the organic combination of energy and the Internet, with the technology in the grid is widely used, and the original smart grid facilities are highly integrated and integrated, the smart grid is the inevitable trend of China's power grid construction, so the smart grid in the future must be a long-term development of the Main line, there are faster development opportunities, it is worth paying attention to!
Second, how the development potential of the smart grid
Grid is a key industry strongly supported by the state, and intelligent is in line with the current trend of green development and digital transformation of the preferred choice, in the supply and demand stimulus and policy support, with the acceleration of the power market reform process, the smart grid industry has a broad prospect. With the gradual implementation of policies, China has accumulated a wealth of project experience and technical achievements in many areas, while also introducing a series of policies to encourage the development of the smart grid industry, the industry will usher in the future significant development opportunities.
Smart grid is the embodiment of the changes in the development of the world's electric power and energy industry, and is an important platform for the implementation of new energy strategies and optimization of energy resource allocation. "Internet + +" under the wind, the smart grid will open the door to the organic combination of energy and the Internet, smart grid layout has also become an important strategic measure for the country to seize the high ground of the future low-carbon economy.
The smart grid industry chain is mainly divided into five major links: power generation, power transmission, power transformation, power distribution and power consumption. The upstream power generation link is divided into renewable and non-renewable; the midstream includes three links of smart transmission, smart substation and smart distribution, and the downstream is the end-user, which is mainly divided into industrial power, commercial power and residential power.
The upstream of the smart grid industry chain is mainly all kinds of power generation energy, which can be divided into two categories: traditional energy and new energy. Traditional energy includes thermal power and hydropower. New energy sources include wind power, nuclear power and photovoltaic power. The state has stepped up efforts to plan and build a new energy supply and consumption system based on large-scale wind power bases, supported by clean, energy-efficient and energy-saving coal power in the vicinity, and carried by stable, safe and reliable extra-high voltage transmission and transformation lines. The downstream of the smart grid industry chain consists of end-user electricity consumption. It is mainly categorized into industrial electricity, commercial electricity and residential electricity.
Grid is the key link of the power system, energy and power in China's carbon peak carbon neutral strategy has a pivotal position, the "14th Five-Year Plan" is the key period of carbon peak, window period, focusing on building a new energy-based power system.
With the technology in the power grid is widely used, and the original smart grid facilities and a high degree of integration and integration, the level of intelligence of the power grid has been greatly improved, the smart grid is the inevitable trend of China's power grid construction.
According to the analysis of the research report "2022-2027 China Smart Grid Industry Market Panorama Research and Development Prospect Forecast Report" by CRRP, in recent years, under the favorable policies, the market scale of China's smart grid has continued to expand, amounting to 79.63 billion yuan in 2020, with a year-on-year growth of 6.78%, and it is expected that the market scale in 2022 will be more than 90 billion yuan.
The construction of smart grid has become an infrastructure to pull China's economic development. Compared with traditional power grids, smart grids have obvious advantages in the four major segments of power generation, transmission, distribution and consumption. Smart grid is also necessary for the development of new energy and smart cities. In this regard, the state attaches great importance to the construction of smart grids, and the outline of China's 14th Five-Year Plan proposes to accelerate the intelligent transformation of grid infrastructure and the construction of smart microgrids.
