Large-scale All-vanadium Liquid Flow Battery Shared Energy Storage Power Station in Severe Cold Regions Put Into Operation

On December 24, the large-scale all-vanadium redox flow battery shared energy storage power station in severe cold areas and the first centralized shared energy storage power station in Northeast China - Jilin Songyuan Qian'an Zhonghui Yuzi Energy Storage Power Station was officially put into operation, filling the need for large-scale energy storage in severe cold areas. Construction and application gaps. In the construction of energy storage power stations, Energy Storage Overload Protection Fuse will play an important role.

The average winter temperature in the Songyuan area is usually minus 10 degrees Celsius, and the extreme minimum temperature is below minus 30 degrees Celsius. According to my country's climate zoning and building climate zone classification standards, Songyuan is in a severely cold area. Jilin Songyuan Qian'an Zhonghui Yuzi Energy Storage Power Station is located in Shuizi Town, Qian'an County. It is organized and operated by State Grid Jilin Electric Power Co., Ltd. and is an important part of the first batch of centralized shared energy storage demonstration projects in Jilin Province. The station has an installed capacity of 100,000 kilowatts/400,000 kilowatt-hours and uses all-vanadium redox flow battery technology. It has the advantages of high energy conversion efficiency, long cycle life, long peak shaving time, and good safety. It is especially suitable for large-scale energy storage scenarios. . According to estimates, the station can consume approximately 300 million kilowatt-hours of new energy power every year, which can effectively deal with the intermittency and volatility of local new energy power generation, improve the power grid's regulation capabilities and stability, and enhance the grid's acceptance of new energy power. ability. The Energy Storage Fuse products produced by our company can be used in the construction of energy storage power stations.

This station is an active exploration of the shared energy storage model. The shared energy storage model is a new model that uses the power grid as a link to provide energy storage services to multiple new energy power stations at the same time. It changes the original relationship of one energy storage power station corresponding to one new energy station into one energy storage power station. Corresponding to multiple new energy stations, it maximizes the efficiency of energy storage systems, improves the level of new energy consumption, and increases the total income of energy storage participants. The station is equipped with Energy Storage Overload Protection Fuse, which provides distribution and storage capacity for 13 new energy power generation companies in Jilin Province. It can not only solve the distribution and storage problems of power generation companies, but also play a large-scale energy storage peak-shaving role.

It is understood that State Grid Jilin Electric Power has fully demonstrated in the early planning and design of the project and established a multiple energy storage technology route including Energy Storage Fuse and a centralized shared construction and operation model, in order to explore the optimal technical route for the development of energy storage in severe cold areas. and provide experience in construction and operation plans, playing a key role in optimizing the regional power supply structure and improving the utilization rate of new energy.
