The largest energy storage power station in Ningxia has successfully connected to the grid
On February 25th, the Mengjiawan 295 MW/590 MWh energy storage power station of Longyuan Power's Tengger "Shagehuang" new energy base in Ningxia was successfully connected to the grid. This power station is currently the largest energy storage power station in Ningxia, injecting new momentum into the development of the local new energy industry and the stable operation of the power grid.
Compared to general energy storage power stations, this power station has the characteristics of quickly achieving frequency and voltage regulation, increasing system inertia, improving short-circuit ratio, and actively stabilizing power grid disturbances, which can greatly enhance the stability of new energy power systems. The cooling system of the battery pack adopts liquid cooling technology, which effectively improves the heat dissipation efficiency and extends the service life of the battery; The fire protection system adopts single PACK level detection+single PACK spraying technology, and the intelligent monitoring system monitors the equipment status in real time through infrared explosion-proof cameras, effectively ensuring the safe and stable operation of the equipment.
After the power station is connected to the grid, it can charge and discharge 190 million kilowatt hours per year based on a daily charge and discharge rate of 95% per charge and discharge. It has a strong energy regulation and reserve capacity, providing strong energy storage support for local new energy generation enterprises. It will play a positive role in peak shaving and frequency regulation of the power grid, peak shaving and valley filling, improving the safety and stability of the power system, and promoting the efficient utilization of new energy. It can effectively alleviate the contradiction between local new energy consumption and power supply and demand.
