Coordinate development and security, and promote the safe and high-quality development of the power industry

Accurately understand the new situation and new problems facing the electric power industry

In today's world, major changes unseen in a century are accelerating, and China's development environment is facing profound and complex changes. An accurate understanding of the current new situation and new problems facing the development of the electric power industry is the premise and basis for doing a good job in the "14th Five-Year Plan" period of electric power work, and it is also an inevitable requirement for ensuring high-quality economic and social development.

The goal of carbon neutrality is steadily advancing, non-fossil energy sources are increasingly connected to the grid, and the reliable supply of electricity is facing challenges. The power industry has relatively large carbon emissions, undertakes important emission reduction tasks, and is also an important support for transportation, manufacturing and other industries to reduce carbon and decarbonize. Under the guidance of the "double carbon" goal, the proportion of new energy generation with high intermittenness and volatility has increased year by year, the construction of UHV AC and DC transmission channels has accelerated, the operation characteristics of the main grid and the system have undergone major changes, the superimposed system has insufficient flexible peak regulation, frequency regulation, voltage regulation and backup capacity, and some regions face double shortage of power in some periods, and the reliable supply of electricity is facing challenges.

With the acceleration of the construction of new power systems, there are deficiencies in the collaborative governance of "source and network load and storage", and the risk of safe operation of power grids is increasing. On the power side, the situation of power gap during peak hours in some areas is still continuing, and the peak power generation capacity is insufficient. On the power grid side, with a large number of grid-connected entities and uneven grid-related performance, the power grid pattern of multiple DC transmission and receiving is constantly strengthened, and the existing power grid operation control theory and modeling analysis method need to be reformed. On the load side, the existing regulation and control means are still unable to achieve comprehensive observation, measurement and control of massive load access, and the demand-side response mechanism still needs to be improved. On the energy storage side, the current energy storage configuration is still insufficient, and the energy storage technology with low cost, large capacity, long time and cross-season adjustment has yet to be broken through.

Entering the new stage of development, the internal and external environment of China's development has undergone profound changes, and the power information network security is facing prominent threats. With the continuous development of science and technology, all kinds of digital technologies are fully integrated into all aspects of power production and operation, the network security boundaries of various scheduling and monitoring systems and production information systems continue to extend, the network security exposure of power systems increases, and the attack paths increase, and the situation of network security in the power industry is more complicated and the challenges are more severe. In recent years, the trend of confrontation in the international cyberspace has become increasingly obvious, and attacks against power infrastructure have continued around the world. We must prevent and actively respond to them in advance.

The scale of power equipment has increased significantly, and extreme events are frequent, which puts higher requirements on power safety work. On the one hand, China's power facilities are widely distributed, large power plants, hub substations and other important power facilities with high load, precision equipment is relatively concentrated, once subjected to natural disasters and other force majeure factors, or the occurrence of switching, main protection refuse to operate mistakenly, may destroy the stability of the large power grid, causing a large area of power outage. On the other hand, in recent years, extreme weather has become more frequent and destructive around the world, with hotter, colder, more waterlogged and drier extreme weather continuing to occur, increasing the risk of damage to important power infrastructure due to disasters.

Balance development and security,

Deeply understand the new deployment and new requirements of the Party's 20th National Congress on electric power work

The Party's 20th National Congress made arrangements for further promoting the energy revolution, ensuring energy security, planning and building a new energy system, and pointed out the direction for further electricity security work. In-depth study and understanding of the spirit of the Party's 20 major Congress, a deep understanding of the Party's 20 major Congress of the new deployment and new requirements for power safety work, is the basic premise of doing a good job of power safety work.
