The Ninth Meeting of the Financial and Economic Commission of the CPC Central Committee pointed out that building a new power system with new energy as the main body. The construction of new power system is inseparable from the construction of digital power grid. Digital power grid is a new generation of digital technology as the core driving force, with data as the key factors of production, with the modern electric power network and the new generation information network as the foundation, through the digital technology and the depth of fusion energy enterprise business, management, constantly improve the level of digital, networked, intelligent, forming a new type of energy ecosystem. The construction of digital power grid will help promote the energy revolution.
Under the goal of carbon peak and carbon neutralization, during the 14th Five-Year Plan period, China's power system will transform to a sustainable comprehensive energy and electricity development mode with high proportion of new energy access, high proportion of power electronic equipment access, and coordinated development of backbone grid, regional grid, local area network and micro grid. On the power supply side, the proportion of wind power and photovoltaic new energy is increasing, and both centralized and distributed new energy are developing. On the power grid side, a high proportion of electric power electronization, AC-DC hybrid connection, micro-grid and multi-energy network access; On the load side, the number of new loads increases, and multiple market players have different interests. At the same time, large-scale energy storage increases, and new forms of energy storage continue to emerge. In the process of power grid transformation, various structural changes pose new challenges to power grid scheduling, control, operation and maintenance, planning, marketing and other aspects. As an important part of the power system, the power grid should not only increase "quantity", but also change "quality". It needs to better promote digitalization, intelligence, adapt to change and realize transformation.
Consolidate key data base. Extensive data acquisition and processing is the basic condition to guarantee large-scale new energy grid connection and consumption. Data acquisition, data storage, data acquisition and intelligent analysis can be realized through a large number of sensors and sensor networks deployed in the power system. Through the construction of digital grid real-time perception system, the various state of the grid can become "transparent".
Speed up research on computing force algorithms. The number of new power system objects increases sharply, the time constant is small, the frequency domain distribution is wide, the dynamic process is mixed, the dynamic behavior is more complex, and the accuracy and rapidity of calculation are required to be higher. Only relying on the empirical model and data, the characteristics and laws of the power system can not be accurately depicted in real time. The testability of new power system can be significantly improved by using digital power grid technology and data-driven method.
Fast collaborative response to rapid change. The new power system puts forward high requirements for the fast coordination of power production and supply and customer service. Through "data + computing power + algorithm", digital power grid can grasp the information of the whole life cycle of power grid operation in real time, and can give feedback quickly and timely, so as to cope with the complex changes of power consumption in real life, and meet the demand of power consumption subjects faster and better.
In addition, digital power grid will also play an irreplaceable role in carbon monitoring, carbon tracking, carbon metering, carbon authentication and other tasks. Through the vast and diverse power system of new forms of energy production and consumption to carry out real-time monitoring, synchronization acquisition and release all kinds of terminal power and carbon emissions data, can build a complete and accurate the whole caliber of electricity - carbon model, trend analysis, and on the basis of carbon in power system and related party's potential carbon reduction, It plays an important role in developing green electricity industry and promoting energy conservation and emission reduction in the whole society.
Looking into the future, digitalization and greening will be the two main arteries of China's economic development, and digital power grid, can be said to be the intersection of digitalization and greening, can realize the mutual promotion and complement each other. The construction of digital power grid will support the greening with the digitization and intellectualization of power grid, thus further promoting the energy revolution and speeding up the construction of an energy power country.
