en.Wedoany.com Reported - The second phase of the Shanxi Datong Fanzhuang Smart Ultra-Fast Charging Station has completed the installation and commissioning of core equipment and officially entered operation, with facilities such as flexible DC interconnection and grid-forming energy storage fully deployed and activated. Located in the Datong Economic Development Zone and constructed by State Grid Datong Power Supply Company, this station is the province's first integrated "solar-storage-ultra-fast charging" smart charging facility. It is equipped with four 600kW full-liquid-cooled ultra-fast chargers, 23 fast chargers, and two V2G chargers, enabling a range replenishment of up to one kilometer per second.
Following the operation of Phase I, the "self-generation, surplus storage" model reduced charging costs and enhanced grid interaction efficiency. Building on this, Phase II completed technological upgrades, optimizing station operation logic and improving charging system balance and power supply stability. The station also integrates 710kW of rooftop solar, 400kWh of energy storage, and 700kW of low-voltage flexible DC interconnection equipment. Liang Shangrong, a fourth-level management expert in the marketing department of State Grid Datong Power Supply Company, stated that flexible DC interconnection technology has broken down barriers between the station's solar, storage, and charging equipment, enabling centralized dispatch of various energy resources within the station and improving energy utilization efficiency. The newly added grid-forming energy storage equipment stabilizes the station's power supply during grid fluctuations and abnormal operating conditions, and flexibly stores and discharges energy during peak and off-peak periods, optimizing distribution network operation.
The project also leverages cross-district flexible interconnection and load mutual-aid technologies to break traditional district barriers, achieving dynamic grid capacity expansion and addressing shortcomings such as insufficient distribution network capacity and rigid scheduling. With a 20-millisecond seamless on-grid/off-grid switching capability and a 27-second full-station black start performance, the resilience of power supply at the grid's end has been significantly enhanced. In the event of sudden faults or extreme weather, the charging station can quickly "self-heal" and continue providing services. Additionally, the project innovates a "technology + intelligence" development model, establishing a practical pathway for smart strategies to participate in electricity market trading, offering replicable experience for refined and intelligent industry operations.
