Unknowingly, 2020 has entered the end of the year. In this final sprint, on December 30, 2020, China's first mobile shared energy storage emergency power supply base was put into operation in Jinhua. After the base is put into operation, it will make up for the shortcomings of the original energy storage facilities and equipment application scenarios. Through modular, mobile, and shareable energy storage forms, the main network peak shaving, frequency modulation requirements and the distribution network non-stop operation and emergency The requirements of power conservation and short-term capacity increase are combined to achieve tasks such as optimization and sharing of energy in the region and quality adjustment.

It is reported that after the base is put into operation, in the event of typhoons, ice disasters and other major catastrophic events, the fashion car can be used to implement on-site mobile power protection, emergency repair power protection, power quality adjustment, and live operation protection in Zhejiang and even across the provinces. Electricity and other tasks.

It is understood that China’s first mobile shared energy storage emergency power supply base covers an area of 5,700 square meters and consists of 8 integrated mobile energy storage vehicles, 6 0.5 MW mobile energy storage cabins, 12 1 MW mobile energy storage cabins, It is composed of 17 mobile transformer cabins, 3 mobile electrical primary cabins, 1 mobile electrical secondary cabin and 1 35 kV 25000 kVA transformer cabin, with a total storage capacity of 34 MWh. All equipment is arranged in containers, such as In the event of typhoons, ice disasters and other major catastrophic events, vehicles can be loaded to carry out mobile power protection work. The electricity stored in the base can provide an electric car to travel 135,000 kilometers without interruption, which is about three and a half times around the earth, but it only takes two hours to fully charge.

"The energy storage system of the emergency power supply base has a wide range of applications. It can provide power support for power grid operations such as peak shaving, emergency repairs, and distribution network operations." The relevant person in charge of the operation and maintenance department of State Grid Jinhua Power Supply Company introduced Jinhua as The only city in Zhejiang Province where UHV AC and DC are located at the same time, playing an important role as a power and energy transmission hub in the province. In 2022, Hangzhou will host the 19th Asian Games. Jinhua is the venue for the Asian Games football group matches and sepak takraw competitions. The importance of ensuring reliable power supply is self-evident. With a mobile shared energy storage emergency power supply base, It can be shipped to where there is a shortage of electricity, and stable power transmission is guaranteed.

Take Jinhua 220kV Huajin Substation as an example. It will supply power for the 2022 Asian Games sub-venue and Asian Games sub-village. From January to September 2020, the maximum load peak-to-valley difference of the station in a single day is 155 MW. After the Jinhua Power Grid's mobile energy storage emergency power supply base is put into operation, it can be used for energy storage at night and discharge during the day At the same time, it drives about 40,000 air conditioners to operate, light up 2 million 18-watt energy-saving lamps, supplement the electricity load gap of the Huajin substation, and provide a strong power supply for the peak summer.

It is worth mentioning that the base also adopts a standardized and safety-certified "plug and play" unified interface mode led by the State Grid Zhejiang Electric Power Research Institute. The Zhejiang Electric Power Research Institute Energy Internet Professional said that the interface can be Improve the power grid applicability of mobile energy storage devices, and solve the problems of traditional energy storage systems in design, construction, transportation, installation, commissioning, and standardization.

In recent years, as the concept of green development has gradually entered people's hearts, it has become a social consensus to actively develop clean energy, and the energy storage industry has ushered in new opportunities. In the future, with the popularization of standardized interfaces for energy storage power supply bases, it will be able to communicate with other energy storage devices in other parts of the province to realize energy storage sharing.
