The Central Political Bureau recently held a meeting and explicitly proposed to deeply tap into the potential of domestic demand, strengthen the planning and construction of the "six networks" of water network, new power grid, computing power network, new generation communication network, urban underground pipeline network, and logistics network. As a hub platform connecting power production and consumption, the power grid is the core link of the new power system, and its importance in the "six networks" is self-evident. According to the 4 trillion yuan investment plan previously announced by State Grid, combined with investments from Southern Power Grid and local power grids, the total investment scale of China's power grid is expected to exceed 5 trillion yuan during the 15th Five Year Plan period. The construction of a new type of power grid will have a significant driving effect on stabilizing growth, ensuring employment, and promoting transformation. During the 14th Five Year Plan period, China's power grid has achieved remarkable historical achievements in building a new form of modern power grid. It has become the world's largest power grid with the strongest transmission capacity, the highest operating voltage level, the largest scale of new energy grid connection, and the longest record of safe operation, providing strong support for high-quality economic and social development. In terms of large-scale resource allocation capability, China has built and put into operation a total of 45 ultra-high voltage transmission channels, including 24 direct current and 21 alternating current lines, and constructed a "power expressway" that spans east and west and north and south. At present, the transmission capacity of "West East Electricity Transmission" in China has reached 340 million kilowatts, accounting for about 23% of the country's maximum electricity load in 2025, and the ability to optimize the allocation of power grid resources is world leading. In terms of power security and supply capacity, the main grid frame of the ultra-high voltage (UHV) regional power grid continues to improve, and the power supply guarantee and comprehensive carrying capacity of the distribution network continue to improve, effectively supporting China's annual average of 80 million kilowatts of new power load demand, ensuring a huge amount of power supply equivalent to the total electricity consumption of the United States, the European Union, and Japan throughout the year, and without large-scale power outages for many consecutive years. In promoting the green and low-carbon transformation of energy, China's power grid has become the world's largest new energy consumption platform, providing strong support for the integration and efficient consumption of over 1.8 billion kilowatts of new energy nationwide, and helping China's non fossil energy consumption to exceed 20% by 2025. With the continuous increase in the proportion of new energy and the acceleration of industrial transformation and upgrading, a stronger, greener, and smarter power grid has become a necessity of the times. Liu Mingyang, Deputy Director of the Electric Power Department of the National Energy Administration, stated that in the future, the power system will exhibit characteristics such as high energy penetration rate, high power electronicization, and high supply and demand randomness, presenting higher complexity and randomness, which puts forward new requirements for the development of the power grid. The "Guiding Opinions on Promoting High Quality Development of Power Grid" jointly issued by the National Development and Reform Commission and the National Energy Administration (hereinafter referred to as the "Guiding Opinions") clearly states that by 2030, a new type of power grid platform with the main power grid and distribution network as important foundations and intelligent microgrids as beneficial supplements will be initially established. Liu Zhiqiang, Deputy Director of the Planning and Development Department of China Electricity Council, stated that the new power grid platform is essentially a modern power grid new form that adapts to the rigid growth of electricity demand, gradually increases the proportion of new energy supply, steadily builds a unified national electricity market, and promotes the diversified development of new power formats. The effective enhancement of resource allocation capability. According to relevant plans, the core direction of the new power grid is to focus on building a new pattern of coordinated development between the main and distribution microgrids. Among them, the main power grid focuses on "strengthening the backbone, ensuring safety, and smooth circulation", continuing to play the role of "ballast stone" for power supply and "main artery" for resource allocation. On April 28th, the State Grid Zhejiang 1000 kV high-voltage AC ring network project started construction. After full completion, it will consume over 57 billion kilowatt hours of clean energy annually, providing green momentum for the energy transformation of the Yangtze River Delta. The total investment of the project line reaches 29.3 billion yuan, making it the largest and most expensive ultra-high voltage AC transmission project in China. The reporter learned that this year, the State Grid will also accelerate the construction of ultra-high voltage projects such as Datong Huailai South Tianjin, Aba East Chengdu, Mengxi Beijing Tianjin Hebei, Panxi ultra-high voltage AC, and 750 kV power transmission and transformation projects in Karamay. The distribution network focuses on "strengthening the foundation, enhancing capabilities, and promoting interaction", strengthening full coupling with the main power grid, and supporting the rational development of distributed new energy. Since the beginning of summer, the Suzhou area in Anhui Province has continued to experience sunny and hot weather, and photovoltaic power generation has entered its annual peak period. In Dangshan County, Suzhou City, State Grid Suzhou Power Supply Company has built and renovated relevant distribution line connection channels to construct a circular network between "major electricity consumers" and photovoltaic power stations on the lines, breaking the original "islands" of the lines and dynamically matching photovoltaic output with high load electricity consuming enterprises, allowing clean electricity to be directly supplied to surrounding enterprises without leaving their homes. Not only does it effectively resolve the risk of midday light abandonment and control the fluctuation range of line voltage within a reasonable range, but it also reserves sufficient interfaces and adjustment space for the integration of new formats such as electric vehicle charging stations, energy storage facilities, and zero carbon parks in the future. Zhang Chi, Director of the Smart Distribution Network Department of State Grid Suzhou Power Supply Company, introduced that in recent years, with the explosive growth of distributed new energy installed capacity, the distribution network is facing common problems such as on-site consumption of distributed photovoltaics and unstable voltage. The company has coordinated the layout of three-level energy storage in substations, transmission lines, and substations, synchronously implemented substation upgrades and new distribution network construction, and connected the entire chain of green power generation, transmission, distribution, and use, exploring a new path of "source grid load storage" collaborative interaction and on-site consumption of green power. Liu Mingyang stated that the next step is to optimize the flow of electricity nationwide and steadily increase the scale of cross provincial and cross regional transmission channels. Accelerate the construction of transmission channels for the "Shagehuang" new energy bases from Gansu to Zhejiang. Strengthen the construction of the main power grid frame and vigorously enhance the flexibility and mutual assistance capability. Continuously promote the construction of new distribution systems, comprehensively enhance their ability to accept distributed new energy and adapt to the development of new business models. Develop smart microgrids according to local conditions, enhance self balancing and self regulating capabilities, and promote the nearby consumption of new energy. The level of intelligence has significantly improved. With the rapid development of digital technology, fully utilizing digital technology and intelligent means to promote the comprehensive upgrading of power grid functions, operation management, and service models has become an important development direction. According to the Guiding Opinions, by 2035, the development of the backbone power grid, distribution network, and smart microgrid will be fully coordinated, and the intelligence and digitization level of the entire life cycle of power grid facilities will be significantly improved. The geological environment in Yunnan region is complex, and natural disasters are prone to occur, posing challenges to the safe and stable operation of high-voltage direct current transmission main grid equipment. Recently, in the face of sudden natural disasters, the production and operation support system of Southern Power Grid Ultra High Voltage Transmission Company Dali Bureau automatically triggered the emergency special patrol mode, remotely activating the "intelligent image+inspection robot+drone" terminal to carry out all-round three-dimensional inspections. Only two people completed the AI inspection and status evaluation of 965 towers and 2 converter station key equipment in 10 minutes from a distance. Compared with the previous method of relying on manual grouping to go to the scene for basic investigation, which took two days, the time for risk assessment has been significantly reduced, and the ability to respond to disasters and ensure safety supply has been significantly improved. The head of the Production Technology Department of the bureau, Gao Yujie, said that traditional manual inspections have low efficiency, high risks, and delayed response under extreme disasters, making it difficult to meet the needs of power grid security defense and emergency supply guarantee. By focusing on the two major fields of digital transmission and digital transformation, and strengthening the deep collaboration of machine to human and intelligent brain assistance, we have achieved one screen monitoring and automatic alarm push for weather disasters such as wind, fire, ice, lightning, floods, and external damage, creating a safe and intelligent digital transmission and transformation power operation model. The new functional positioning and physical architecture of the power grid cannot be separated from technological innovation, development, and breakthroughs. The Guiding Opinions propose to promote the empowerment of artificial intelligence technology and digital technology in the development of the power grid. Promote the integration of digital technology and data elements into the power grid business, and promote the deep application of artificial intelligence technology in power grid planning and construction, equipment management, regulation and operation, power supply services, security defense, and other aspects. By combining advanced technologies such as quantum communication, IoT sensing, 5G-A/6G, we aim to expand the application scenarios in the field of power grids. Liu Zhiqiang suggested that in terms of technological innovation, we should focus on tackling key technologies such as smart grids and flexible DC, and accelerate the research and development of domestically produced core equipment and its large-scale application; Accelerate the empowerment of "artificial intelligence+power grid" application scenarios; Promote the construction of a collaborative and interactive standard system for "source grid load storage", and support the construction of a new power grid platform.
