On July 6, Zhejiang's first metropolis commercial air -conditioning flexible response demonstration project landed in Ningbo, realizing the real -time monitoring and flexible adjustment of the air -conditioning system, such as the air -conditioning system of Ningbo commercial complexes, to further expand the demand side side to further expand the demand side Adjustable energy capabilities to improve the comprehensive utilization efficiency of public construction units.

Since the beginning of this year, the State Grid Zhejiang Electric Power Digging has deeply digged power resources inside and outside the province, strengthened the scheduling of power grid, deepened the application of new power system results, promoted the healthy interaction of the source network lotus, improved the power system regulation, and fully ensured the reliable supply of energy and power.

Policy empower the power to protect the power to form a joint force

On June 29, the State Grid Zhejiang Electric Power and the Luzhou Municipal Government signed a strategic cooperation framework agreement to jointly promote the construction of a new type of power system to ensure the reliable supply of power. According to the agreement, the government will increase the support of new energy storage policies, explore the establishment of county -level demand response subsidy funds pools, and promote the response of the entire society's resources to participate in the power grid.

In recent years, as the country has proposed the goal of "carbon peaks, carbon neutralization" and building a new type of power system, new energy has entered a period of rapid development. However, the volatility and intermittentity of the new energy cause uncertainty to the balance of power, and need to improve the resource regulation capacity in all aspects.

As a coastal economy province, Zhejiang, with the continuous increase in power consumption energy in recent years, the characteristics of high -rate, high proportional cleaning energy, and peak valley difference rate of high -proportion of power grids have become more obvious. State Grid Zhejiang Electric Power proposes to build a "circle of friends" to build electricity, gather resources from all parties, and improve the system regulating ability to cope with the pressure caused by high load and uncertainty to the operation of the power grid. The policy empowerment is the primary factor.

On July 2nd, Baihe Beach -Zhejiang ± 800 kV high -voltage DC transmission lines in the Zhejiang section achieved the entire line, and the "circle of friends" contributed. The efficient collaborative mechanism established by the power grid company and the government will timely solve the problems encountered in the construction of the project, ensure that the Zhejiang section is the first to penetrate, and lay a solid foundation for the early delivery of power arteries.

This is the epitome of Zhejiang's deepening policy empowerment and creating electricity to protect the "circle of friends". As early as 2021, all counties (cities, districts) in Zhejiang issued a "new energy+energy storage" policy, and new energy projects were added at 10%of the capacity to allocate energy storage to improve the power system regulating energy and ensure the supply of power safety.

Right now, the scale of such a "circle of friends" is continuously expanded and the category is becoming increasingly abundant. In the new city of Fuchun Bay, Hangzhou, the State Grid Zhejiang Power promoted the Hangzhou Municipal Government to introduce the cost sharing mechanism of power access engineering. Expenses of more than 500,000 yuan. With this policy landing, Hangzhou alone is expected to save more than 1 billion yuan for enterprises in one year. At present, all the 11 municipal governments in Zhejiang have issued a mechanism for the cost of power access engineering.

Energy storage support power guarantee has elasticity

On June 30, Changlong Mountain pumping water storage power station No. 6 was put into operation. At the peak of electricity loads in summer, Zhejiang Power Grid added 2.1 million kilowatts to adjust the power support. At this point, Zhejiang has been launched in Zhejiang's total capacity of 6.68 million kilowatts, and more regulators have been used in power balance.

As an important regulatory resource for the construction of a new type of power system, energy storage has attracted more and more attention, the scale of construction has continued to expand, and the amount of investment has continued to increase. On June 22, Hangzhou announced that 5 water pumping projects were built in 2030, with a total investment of more than 40 billion yuan. The data shows that the total installed capacity of the water storage power station in Zhejiang is 10.6 million kilowatts.

The "Fourteenth Five -Year Plan" of Zhejiang Province Energy Development "is clear, accelerating the construction of water storage power stations, and building a hybrid (small and medium -sized) pump storage power station. above.

State Grid Zhejiang Electric Power also strengthened the balance adjustment function of the energy storage power system, and accelerated the development of various types of energy storage power stations. On June 17, the country's first 35 -kilovolt -hanging energy storage power station was operated in Shaoxing to further enhance the support capabilities of the grid, and used as a large -scale backup power supply to effectively improve the recovery capacity after failure and reduce the economic loss of power outages.

On July 8th, Da Chen Island, Taizhou City above the East China Sea, was officially put into operation on July 8th. Send it to the large power grid to achieve the full consumption of clean energy and enhance the power grid regulation capacity.

According to the "Fourteenth Five -Year Plan" Energy Storage Development Plan for Zhejiang Province ", Zhejiang will build a new type of energy storage of 3 million kilowatts during the" Fourteenth Five -Year Plan "period. State Grid Zhejiang Electric Power gives full play to the advantages of new types of energy storage, good matching with new energy development, and good economy of pumping and storage economy, stimulating significant economic effects, coordinating various energy storage development, supporting new power systems Construction to ensure the safety supply and green low -carbon transformation of Zhejiang.

Digital traction power guarantees for deep excavation potential

On June 30, the State Grid Zhejiang Power launched the "one -click response" practical exercise in Zhejiang's power load, simulating the fault of the main change of the Hangzhou Qiaosi Supply District, which caused the section over the section. Negative removal part of the remote sub -circuit is not important to ensure the safe operation of the power grid.

2022 is a key year for Zhejiang to implement the "double carbon" target task and build a common prosperity demonstration zone, and it is of great significance to ensure power supply. On the basis of accelerating the layout of the power supply and improving the structure of the grid, the State Grid Zhejiang Electric Power uses digital traction new power system construction, builds a new type of power load management system, promotes the healthy interaction of source network loads Level. On May 29th, the staff of the State Grid Hangzhou Yuhang District Power Supply Company came to Wanda Plaza, Yuhang District to install the load control load control load control load control load control load control circuit for the power distribution room. Under the premise of not affecting elevator safety and lighting, flexible adjustment of electricity is not affected by elevator safety and lighting.

On June 30, the State Grid Zhejiang Electric Motor Company completed the real -time adjustment of electric vehicle adjustable loads within the province through the charging load aggregation platform, and issued the power adjustment instructions to 4587 charging piles and 8 power stations, the maximum peak peak cutting. The load is 126,000 kilowatts.

Since the beginning of this year, State Grid Zhejiang Electric Power Deepen the application of energy big data, excavate the full time -scale user resources, and build a total of 11 million kilowatts, 2 million kilowatts hours, and 1.3 million kilowatts of minutes. 10,000 kilowatts, laid a solid foundation for the peak summer power guarantee.

State Grid Zhejiang Power further taps the value of big data. The power grid company and the government jointly build a big data center for energy, promote the co -construction and co -governance of energy data, and use digital to empower the optimization of energy power. In Luzhou, local power supply companies optimize the system balance level and ensure the safety supply of power safety by opening the carbon accounts, implementing energy -based management, "green energy+energy efficiency services", and optimizing the total amount of power use and time.

With the peak of electricity consumption in summer, Zhejiang refined and implemented 2 million kilowatts of electricity supply in the province, ensuring that the provincial foreign purchase of electricity increased 2 million kilowatts, and the peak adjustment capacity of the demand side was 3 million kilowatts to ensure that the power balance during the summer period during the summer period Essence At the same time, deepen the application of the construction of new power systems, give play to digital traction, mobilize the entire social resources, improve the power system regulating power, and fully ensure the power safety supply of power.
