In the current landscape, the explosive growth of AI computing power and the widespread adoption of high-power electric vehicle charging stations are imposing unprecedented demands on power grids. Smart grids now require a more robust and intelligent computational "heart."
Known as the "intelligent power router," the Solid-State Transformer (SST) is capable of effectively replacing traditional power frequency transformers. It enables millisecond-level voltage regulation and flexible AC/DC conversion, significantly mitigating the instability introduced by new energy grid integration and the power supply pressures of high-demand scenarios. This technology stands as a foundational piece of core equipment for constructing new-era power systems in the age of AI and renewable energy.
Nanjing's Jiangning District is one of China's regions with a high concentration of smart grid industries. It is home to nearly 200 enterprises in the sector, including industry leaders such as the State Grid Electric Power Research Institute (NARI Group) and the China Electric Power Research Institute, achieving comprehensive coverage across the entire chain from generation, grid, load, and storage to regulation.
Leveraging its existing industrial foundation and the leadership of major firms, Jiangning District is now targeting the multi-billion-yuan distribution network SST market. The focus is on accelerating the development and manufacturing of core equipment and system integration. The district is speeding up the construction of solid-state transformer projects and related applications, actively fostering a cohort of upstream and downstream enterprises in the industrial chain, such as Hongjing Intelligent and Zhongdian Transformer. These efforts are aimed at cultivating a regionally influential solid-state transformer industrial cluster.
