On July 14, 2023, General Li Qiang of the National Academy of Health, was in charge of convening the Standing Meeting of the National Academy of Health, pointing out that ensuring the safe and stable supply of power is a major event for national actors. Each aspect must implement its responsibilities and form a joint force, and do a good job in ensuring the supply of power and power with a sense of responsibility of “staying at a time and not being able to make peace of mind”. At present, my country is in the transition period from the transformation from the traditional power system to the new power system. The power transformation is doubled. Sugar daddy is clear that the carbon reduction mechanism is becoming more perfect every day, and some power supply and demand are tight. In this coexistence of opportunities and challenges, certainty and indeterminate sexual intercourse, we must make full use of the New York war influence of the Internet in the supply system to double the safety and reliability of Sugar baby, green, efficient and intelligent modern Internet, to support the power of green low-carbon transformation and high-quality development of economic society.

Future power security and supply risks
From the demand perspective, my country is still the largest developing country in the world. With the construction of modern industry system, the expansion of demand to promote consumption and digital economic energy, the consumption of residents has recovered stably after the epidemic, and the economic development is high-quality. daddy has recently increased its demand for power consumption. With the profound advancement of the development of the western region and the emergence of the central region, the power needs in the central and western regions to exist in a large area of development; under the promotion of the electricity consumption policy, the power needs of the central and western regions need to exist in a large development space; Due to the influence of baby‘s widespread and low-level career, the load in summer shows a rapid growth and growth. In the future, the “dual-cephalus” feature of using electric loads in summer and winter will be doubled. Under the influence of new diversified loads such as electric cars, the power load characteristics are even more complicated.
From the power side of the power supply, our country’s power supply is still mainly coal-electricity, with coal-electricity generating capacity accounting for more than 60%, and the dependence on natural atmosphere is higher than the external dependence of natural atmosphere.ay escort is still above 40%. The supply of coal is not affected by ground politics, price fluctuations, environmental purification, carbon emission reduction and other reasons, resulting in tight supply, rising operating costs of the machine, increasing equipment risks, and lack of top peaks; safe replacement of new forces is not yet fully formed, the overall capacity accumulation is small, and the adjustment effect is unlimited. In the future, the high proportion of new forces will be eliminated and the supply and pressure will be strengthened.
The shape of the power supply guarantee surface in the southern region
First, the space for the load capacity growth in the southern region is huge, and the medium- and long-term supply guarantee format is doubled and severe. The southern region is a region with intensive national strategy layout. With the profound implementation of national serious strategies such as the Hong Kong and Macao Bay Area, Hainan Self-Trade Port, and Shenzhen Pilot Demonstration Zone and the accelerated construction of new development formats, the internal industry in the power supply area has accelerated its transformation and upgrading, and the growth has continued to flow, and the concentrated effect should be obvious. It is expected that by 2060, the electricity consumption of the entire society in the southern region will be about 35,000 kilowatts, accounting for about 20% of the total electricity consumption. In the future, the reality of the “dual carbon” goal of Hong Kong and Macao also requires settlement in the southern region to provide green force guarantees. However, the non-fossil dynamic resources in the southern region are relatively scarce. After considering the power flow within and outside the region and the relatively certain new power supply, it is expected that the medium- and long-term power gap in the southern region will expand further, and the power supply will become more prominent.
The second is that the demand for the positioning and transformation of traditional fossil dynamics is convex, and non-fossil dynamics are lacking in potential. The coal-electric bearing carries the dual loading of the power and quantity guarantee, which is the main basis for ensuring power supply. In the future, coal-electricity positioning needs to transform from profit-making through power consumption to assisting services such as payment and peaking, and provide sufficient and useful power generation capabilities to ensure power supply and supply. In recent years, as international coal prices continue to rise, coal-electric enterprises’ fuel capital has greatly improved. According to the calculation of a 600,000 kilowatt coal-electric machine unit on a platform, the network power generation limit is about 700,000 to 1 million yuan per day, which is far beyond the non-planned suspension of operation inspection price. Therefore, the department’s power generation enterprises can extend the repair time and be inspected, and are unwilling to launch electricity online. At the same time, due to the rising price of coal, large project operating pressure, and weak investment intention of the owner, there is a situation of “indicators and unconstructed” in the development of coal and electricity in the department. The system’s power generation can not match the increase in the load of electricity, which reduces the balanced conflict between power supply and demand. At the same time, the hydroelectric power in the southern area has entered the deep development stage, and the remaining large-scale hydroelectric power supply is lacking. It is subject to the high-level environmental protection, environmental protection and development of capital, and the development process of hydroelectric power stations in the district is slow. In addition, affected by the change of nuclear power in Fukushima in Japan and the maturity of third-generation nuclear power technology, the progress of domestic nuclear power approval and implementation has been delayed in recent years, and has increased uncertainly.
The third is that new momentum continuesWith rapid development, only by ensuring power supply and system adjustment under extreme conditions can the problem be confirmed. In the 14th Five-Year Plan and the middle and long periods, new forces in the southern region will develop rapidly, with new power installations expected to reach 200 million kilowatts in 2025, accounting for 31%; in 2030, new power installations reach more than 30 million kilowatts, and gradually become the first power supply for installations and power in the carbon neutrality process in 2060. The new power “large machine has small output” characteristics are obvious, the power generation “eats with the sky” has a protruding attribute, “extremely hot and windless” and “lightless at night”. The cost of the top peak of the system is relatively low, and the current stage of power balance support is lacking. The low resistance and weak support of the new power generation equipment bring challenges to the safe operation of the Internet. The main peak power supply in the southern region is coal and hydroelectric power. The water and electricity, which has strong functions during flood season, has comprehensive application tasks such as flood control. Only when the adjustment period is severely re-issued, the adjustment period is constantly dozing off with new power installations such as wind and photovoltaics. After waking up, she found that she turned out to be a supporting role in the book. Her growth, only relying on the regular power adjustment period, will not be able to achieve the stable balance and power adjustment period of the Internet, and the peak pressure of the Internet is increasing.
The power network supports power supply and load is a significant effect
The power network is connected with power supply and load, which is the key link to promote the “source load storage” and will double the significant effect in terms of power supply support, such as West Power East transmission, transportation, and installation of power supply in the domestic power supply.
First, we will use the West East to deliver high-quality distribution Escort manila to support the power supply in the East, Central and Southern energy-using areas. The electricity demand in the eastern, central and southern regions of my country accounts for about 70%, which is the energy-consuming area. However, 70% of the hydraulic resources are concentrated in northeastern regions such as Sichuan, Yunnan, and Xidiao. More than 80% of the upper wind energy and solar energy resources are distributed in the western and northern regions, and there is a reverse distribution between the middle and the economic forces. The Internet connects the Northeast Hydropower Base, the New Power Base in the Northeast North, and the Central and South TC:
