when the sun rises from the Gobi, the Zhangye 300MW/1200MWh independent shared energy storage power station supplied by Shangneng Electric is operating efficiently. In the low hum of transformers, clean energy is imported into the power grid with this “super charging treasure”, injecting new green kinetic energy into the livelihood and economic development of Hexi corridor area, and adding a beautiful color to colorful Danxia.
the northern foot of Qilian mountain has a total amount of 7.76 million kilowatts of scenery that can be developed. however, due to the lag of power grid consumption and the annual power generation exceeding 2.2 billion kilowatt hours, the local area still has the serious problems of surplus photovoltaic power generation during the day and insufficient power consumption at peak at night .
in order to solve this dilemma, the energy storage power station has become the key to opening up the “last kilometer” of new energy consumption in the region: the 4-hour long-time system matched with the power station can store up to 1.2 million kilowatt-hours of green electricity at a time, and can reduce the wind and light abandonment by more than 79 million degrees per year , significantly improve the consumption capacity of Gansu power grid .
the wind and light in the Hexi corridor have since had a “energy relay station” that can be stored and deployed, and the 1250kW centralized PCS of shangeng electric is the surging heart of this system that undertakes energy conversion. Compared with the previous generation of products, the power density of the product is increased by 25%, the full-load efficiency in the full voltage range is> 98.5, and the power conversion is efficiently enabled within the smaller footprint ; By reducing the number of battery clusters connected in parallel by 50%, the charging and discharging capacity of the system is increased by 0.75 , fully release the full life cycle potential of the battery . The millisecond response capability of the product provides strong support for the power grid auxiliary service capability of the power station , and protects every degree of green power with the “double engine” of technology and safety.
The integration of optical storage is an inevitable trend in the development of the industry, and is also the core track for the deep cultivation of Shangenergy Electric. In the future, Shangneng Electric will continue to focus on cutting-edge application scenarios, respond to customer needs with innovative technologies and products, and inject strong momentum into the early realization of the dual-carbon goal.
