In 2022, the “14th Five-Year Plan for Modern Power Systems” (Development and Reform Power [2022] No. 210) issued by the National Development and Reform Commission and the State Administration of Dynamics will provide clear indicators for the flexibility of power systems. Only by power coordination can the operation of power coordinated operations continue to strengthen, and by 2025Sugar In the year, the proportion of flexible power supply reached 24%, and the side effect of power demand should be 3% to 5% of the maximum power load. Pumped storage is the main component of the flexible power supply, and the construction procedures for pumping storage during the 14th Five-Year Plan period have clearly accelerated. In March this year, the “Guiding Opinions on Strengthening the Power Network Peak Energy and Intelligent Escort Temporary Construction” (simplified “Guiding Opinions”) jointly issued by the National Development and Reform Commission and the State Administration of Dynamics proposed that by 2027, the power system adjustment will be significantly reduced, and the scale of pumped storage power stations will reach more than 80 million kilowatts. The development of pumped storage is ushering in a golden period, and its high-quality development is attracting attention. Recently, this magazine visited Zhao Zenghai, a member of the Party Committee of the General Office of Hydropower and Water Conservancy Planning and Design, and distributed his friends his profound thoughts and policy suggestions on the development of pumping and storage from the perspective of system thinking and long-term planning.

Issued recently The “Guiding Opinions” clearly requested, “Stately optimized layout and build and make good use of various types of adjustment resources, promote the scale-based and high-quality development of power side, power website side, and load side, and after the structure and telephone connection, the little girl began to use short videos again. Song Wei asked with concern: New power development is a suitable power systemSugar babySugar babyStandard adjustment ability. “What are the characteristics and advantages of pumped storage compared with other flexible adjustment power sources? How to plan the construction of pumped storage?

Zhao Zenghai:

Today, in addition to pumped storage power stations and new energy storage, the flexible power supply also has power types such as gas, water and electricity. In the future, the ignition will also have flexible adjustment capabilities and slowly change the color of the head. my country’s gas and electricity development scale is affected by gas sources, and water and electricity are affected by resource resources, and the space for continuous growth is still unlimited. It is expected that the gas TV scale will be about 200 kilowatts and the hydroelectricity will be about 500 kilowatts by 2035.

Compared with new energy storage, pumped storage power station equipmentThere are three advantages in the following aspects: First, the safety performance is advantageous. In the new power system, the new power output is strong and the power network will frequently use the modular power supply. The existing operation data confessed that pumping storage technology is mature and can fully meet the needs of new power systems for frequent applications. The commercialization time of new power storage is short. It seems that the frequent applications of power systems will still affect its life cycle, and safety is still to be verified; second, economical advantages, the operation period of pumping storage power stations can reach 100 years, and after the loan period is over, its capital will drop rapidly, even Sugar baby can reduce 80%. From the perspective of the entire life cycle, pumped storage power stations are economically more affordable, 1.5 times to 2 times that of new energy storage; third, they are technically superior, which is comparable to new energy storage. Pumped storage power stations have a longer tuning, “Oh, then your mother should be very excited when she knows.” Jun sighed, “There is a long time, and it can supply the system to convert the transformation habits and adjust the performance of the meter, and the machine system The model can reach a million kilowatt level, which is more obvious to the support of the provincial power system. The new energy storage scale is small, the service scope is small, and the operation cycle is short. The support of the power network is not as good as that of the pumped storage power station.

Since the 14th Five-Year Plan, pumped storage has ushered in a period of rapid development, and the policy support is also increasing. In April 2021, the National Development and Reform Commission issued the “About Into an IntegrationSugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar daddySugar price change〔2021Escort] No. 633), and made clear regulations on the two departments’ related issues such as the electricity price policy and price division diversion mechanism. In September of the same year, the National Bureau of Dynamics issued the “Medium- and Long-term Development Plan for Pumped Storage Energy (2021~2035) 》, propose development goals, key tasks and guarantee methods for the entire industry system. Under the accelerated development of pumped storage, new concepts and new forms have gradually expanded into new formats. From the perspective of development thinking, pumped storage has transformed from the “luxury product” of the development of power systems to the “must-end product” of system development, with the number from a small to a large number and the layout has become more diverse. From the perspective of service objects, pumped storage is Sugar baby From the original performance of satisfying the peak, valley filling, frequency and phase adjustment of the power system, it has transformed into a new industry to generate energy-energy influence and construct diversified integrated bases, and its service targets have been diversified and its industrial development has been doubled.

EnvironmentalityTo adjust the demand scale of power supply, we need to consider the development needs of new power systems and new power systems in a comprehensive manner. In April 2023, the National Bureau of Dynamics issued the “Notice on Promoting a Problem in the Construction of Pumped Storage Plans” and requested the “Certification on Fair Needs for Pumped Storage” as soon as possible. The focus of the pumped storage demand certification is the power expansion plan. “Pumped storage + new energy storage + new power” is one of the low-carbon power expansion plans that can meet the demand for new power and power in the future. Using “pumped storage + new energy storage” to supply new power (regular) support, and using new power to supply new power support is an inevitable choice for the realization of power clean, low-carbon, safe and efficient transformation and development. Following the “dual carbon” target request, regulating various types of power supply, comprehensively considering the fair application rate of new forces, and the ability to afford electricity prices. According to analysis and analysis, the national pumped storage and new energy storage demand will be about 600 million kilowatts by 2035.

“Currently drawSugar daddyThe scale is still lacking, but it must develop as needed and develop in an orderly manner”

“China Power Enterprise Governance”:

In May of previous years, the General Department of the National Power Bureau issued the “About the First-class Development” by the General Department of the National Power Bureau. A step-by-step notification on matters related to the construction of pumped storage planning” pointed out that “there are currently situations such as insufficient later verification, poor tasks, unclear requirements, and over-project applications in the department.” How do you deal with problems that can exist in the actual development of pumped storageEscort?

Zhao Zenghai:

Overall, the pumped storage energy planning is governed by the National Dynamics Bureau. The National Dynamics Bureau has always been closely grasping the “planning entry link”, and the pumped storage energy has always been developing in an orderly manner in accordance with the planning. The competent department of the National Movement attaches great importance to the phenomenon of self-scrutiny of pumping and storage in some regions, strictly follows the planning and formulates and adjusts the planning based on the requirements scale evidence in accordance with the principles of “franchise the total, improve the quality, choose the best, enter and out, and dynamic adjust TC:
