Energy momentum: How should the carbon neutralization of the power industry be achieved?

Recently, abnormal weather such as heavy rain, high temperature, hail, and floods across the country frequently staged in different regions. From the perspective of timeline, climate change brought by global warming, glacier melting, and sea level rising greenhouse effects are seriously affecting our living environment. With the gradual importance of global climate change in various countries in the world, a series of carbon emission plans such as carbon peaks, carbon neutralization, and other carbon emission plans have gradually landed.

Data show that in my country's carbon emissions, energy combustion is China's main source of carbon dioxide emissions, accounting for about 88%of all carbon dioxide emissions. The use of energy combustion is mainly used for power generation. Data show that in 2019, power carbon emissions were 4.227 billion tons, accounting for 43%of the total emissions of the whole society. Energy system decarburization is the key to achieving carbon neutrality, while the power industry's decarbon is the top priority.

So the question is: What are the paths of the power industry in helping to achieve carbon neutrality? How does the digital transformation of the power industry support the carbon neutral and transformation of the energy system?

Road of decarburization

In daily life, there is a power plug that is now available. Plug in the power cord to mobilize the switch. Electrical appliances such as air conditioners, refrigerators, and computers starts to run. In the factory, automated machines are inseparable from the support of power. Small ones. Behind the switch is a huge and precise and complex power system.

The power system behind the power industry, consisting of power production and consumer systems composed of power generation, power transformation, power transmission, power distribution, and power consumption. The road of decarburization in the power industry is mainly based on these key links.

1. In the power generation, thermal power generation is the main source of electricity. According to data from the National Bureau of Statistics, thermal power generation, mainly based on coal -fired power generation, accounts for 71.19%of the national power generation. The second is hydropower, accounting for 16.37%, and then wind power and nuclear energy. Finally, solar power generation, the proportion is only 1.92%. In the existing thermal power generation industry, various types of net coal technology are used to transform the combustion efficiency of thermal power generation to reduce the carbon row. The combustion process control optimization and improve the efficiency of combustion of the unit.

In addition to the supply of thermal power, the scale of wind power and photovoltaic power generation continues to increase. The southwestern region is rich in hydropower, and the construction of large hydropower bases is promoting in an orderly manner. The northwest is mainly wind power and photovoltaic power generation. For example, photovoltaic power generation, the National Energy Administration data shows that as of 2021, the cumulative domestic photovoltaic installation scale reached 305.99GW, an increase of 21.86%year -on -year. 54.88GW, from 2016-2021, the annual compound annual growth rate of the domestic optical installation machine was 32.31%, showing a rapid growth trend.

2. In the substation, the substation is hailed as the nerve center of the power system, and the effects of transforming, allocating, controlling, and monitoring electrical energy. The substation will also consume electricity during the working stage. It is estimated that the total loss of my country's transformer accounts for about 10%of the power generation. The carbon row of this part should not be ignored. The substation will embed some intelligent devices to perceive the state of the control of the device. Scientifically optimize the operating strategy, improve the overall energy efficiency level of the substation, and promote energy conservation and emission reduction.

3. In the transmission power distribution and other links, rely on the scheduling system of the grid to maintain the system balance of power generation and load. By building an advanced intelligent distribution network, we can improve the ability to optimize the allocation of resources. Smart grid has been promoted for nearly ten years, and the level of automation in each link has occupied the top. Digital intelligent intelligence technology and measures are being promoted to promote the efficient and coordinated system of source network loads to improve system regulation capacity and improve the level of power demand.

Of course, there are also supplementary measures outside these paths, such as solving the interval between the grid grid grid -connected process and the hidden security hazard measures, including various types of physical and chemical energy storage methods, such as pumping storage, compressed air, battery energy storage energy storage, energy storage of battery storage Energy storage technology to solve the dilemma of clean energy grid -connected use, and promote the widespread application of low -carbon cleaning power generation technology and the iterative upgrade of smart grid technology.

Digital technology combines the traditional power electronics technology in the power industry's decarburization road in the power industry. Through intelligent coordination or optimization, it will drive the carbon row of the power industry to accelerate carbon neutrality. The digital transformation of the power industry is typical in the new power grid system.

Digital transformation obstacles

If readers who have learned about the power system industry may know that the production model adopted by the traditional power system is "source with the lotus". What does that mean? The traditional power system can adjust the power supply of the power according to the load on the electric side, and use the controllable power generation system to match the poorly measured power consumption system, rolling adjustment during operation, so as to achieve the safety and reliability of the power system to achieve the safety and reliability of the power system run.

As the scale of renewable clean energy increases, new energy power is incorporated into the large power grid, which will change this model. New energy such as wind energy and solar energy is easily affected by the climate. The production of electricity is random and volatility. The power generation and load in the power grid must always maintain the power balance, which also challenges the security and stability of the power grid. The research and development and extensive application of large -scale energy storage technology is the guarantee of improving intermittent and volatility of renewable energy power generation. It can significantly improve the level of elimination of renewable energy such as wind and light, which is the key to promoting the transformation of the energy structure.

Whether it is to adapt to the large -scale and high -scale grid -connected or elimination requirements of new energy sources, or widely access to distributed energy facilities such as energy storage, it is necessary to use digital technology to empower the grid to promote the coordination and interaction of source network loads, promote the new model, and promote the new type The power grid upgrades to a more intelligent and more general energy Internet. The digital transformation of the new power system power grid requires a new generation of digital technologies such as cloud computing, big data, the Internet of Things, and artificial intelligence to digitize traditional grids to support the green economy transformation of the power system. However, digital technology faces a lot of obstacles in the process of empowering the intelligent green transformation of the grid.

At this stage, the power industry is highly automated and the basic system of informationization is complete. Therefore, in terms of digital transformation, power companies pay more attention to the application of new technologies such as IoT, big data, and artificial intelligence. The establishment of the smart system model of data -driven decision -making in the power grid is not mature; in the grids of new energy power, the power grid -driven power grid predicts the power of power generation is not accurate. Stability and security cannot be fully guaranteed, the control of the power grid is difficult, and the situation of abandonment is high.

At the same time, the data associated with the power grid equipment under the empowerment of digital technology is huge, and a large amount of production and operation data information is split. There is no unified management platform that integrates various types of information better. Various types of information are in the state of the islands on their respective platforms. , Can't play the effect of data. And these data are related to the sensitive data of the people and resources, and also put forward higher requirements for network security, and the construction of security data protection system has also become a test.

The digital green transformation of the power grid is in the initial stage of development. These problems and challenges need time and technology to run in and the road of carbon and neutrality in the power industry. It will be easy to reach overnight.

Unwilling general trend and breakthrough

The digital transformation of the power industry is also aimed at the core pain points of the Green Reform of the power grid system. In the power industry, in addition to the various key links of the power grid system, the digital technology also has an integrated form such as the industrial Internet platform to enhance the pair. Data collection, analysis, and application.

At present, power equipment manufacturers, big data AI technology service providers and power companies cooperate, and use AI, the Internet of Things, and big data to analyze modeling through the technical platform access source, network, and load real -time data. Essence On the one hand, by supporting new energy, the efficiency of operational operations is improved by unmanned duty, less people on duty, and regional maintenance models, and on the other hand, it improves the efficiency of new energy power grid grid and overall power consumption of the power grid system, reducing energy loss energy consumption, and energy loss consumption. , Support the optimized allocation of energy resources of power grid, promote green production and consumption of energy, and ultimately support the achievement of the "dual carbon" goal.

The carbon neutralization of power companies is a complex system engineering. There are many links involved. The green reform, operation control, and security protection of the power grid system become more complicated. The grid of energy and power supply, the investment of power electronic technology and equipment, brings the larger volatility of the entire power grid system. Although the reform is difficult, the path of carbon neutralization of the power grid system is irreversible.

Although clean energy will bring challenges, new technologies such as hydrogen energy, energy storage, and controllable nuclear fusion of hydrogen energy may achieve technological breakthroughs and reach the degree of commercialization, which will also bring breakthroughs to the transformation of the power structure. In all kinds of news, we will always see the news of fast -charging batteries and energy storage batteries in new energy vehicles. The innovation of lithium battery technology will bring disruptive innovation to the power system. Solve the challenges brought by ultra -high proportional new energy access to the power system. However, energy storage technology still requires a long way from laboratory to commercial use. This uncertainty brings space to the development of other technologies.

Whether it is hydrogen energy, energy storage, or controllable nuclear fusion technologies, it is not possible to completely solve the problem of power grid systems for the time being. It is still in the initial stage of exploration and development, and it is facing a lot of twists and turns. However, in the long run, the carbon neutrality requires the evolution of the power system into a "zero -carbon power system". The balance of the power grid needs to be achieved with the help of digital technology and emerging technologies. Structural deepening and reform also bred a new one. Ring's scientific and technological innovation and opportunities.

Not only means stepping on the development of Dongfeng, it can also allow technical service providers to seize the highlands of digital technology and improve competitiveness. If the digital capabilities in these complex systems are radiated into the changes of other similar scenarios, it will also bring efficiency improvement to more industries. On the way to achieve carbon neutrality, it will expand into a wider industry, create more creation, and create more Large social value.
