The grid-forming vanadium flow battery energy storage project at the Xinhua Hydropower Wushi Energy Storage Power Station, which was supplied by NR Electric, successfully passed the artificial short-circuit test in one go. This marks the first grid-forming vanadium flow battery energy storage project in the world whose core equipment and systems have successfully withstood the most stringent grid fault conditions. After evaluation by all parties, the project has been successfully transferred to commercial operation.

The Xinhua Hydropower Wushi Energy Storage Power Station Project has a total capacity of 500MW/2,000MWh, making it the largest grid-side hybrid energy storage power station in China to date. The project adopts a hybrid energy storage technology combining 250 MW/1,000 MWh lithium iron phosphate batteries and 250 MW/1,000 MWh vanadium flow batteries, aiming to fully leverage the characteristics of different battery technologies (lithium iron phosphate batteries offer fast response times and high power density; vanadium flow batteries are long lifespan, high safety, and suitability for long-term energy storage), to meet grid support, peak shaving, frequency regulation, and renewable energy integration requirements. NR Electric as the core technical solution provider and equipment supplier, is responsible for the entire station's energy management system (EMS), power management system (PMS), and all grid-connected converter integrated equipment for the vanadium flow energy storage system. The successful completion of the short-circuit test for the vanadium flow storage system serves as strong evidence of the performance and reliability of NR Electric's grid-forming PCS in large-scale vanadium flow storage applications.

Short-circuit test completed successfully
NR Electric has long been committed to research and innovation in the field of power system safety and stability. Pioneering the use of grid-forming technology to address the growing complexity of power system construction challenges, NR Electric has developed the ideal synchronous voltage-source grid-forming technology through extensive research and practical application. This technology enables energy storage converters to simulate or even surpass the characteristics of synchronous generators, providing the power grid with robust inertia, damping, and short-circuit capacity support. This significantly enhances the stability and resilience of new power systems dominated by renewable energy sources. This project marks another major breakthrough for NR Electric's grid-forming technology, following its successful application in lithium-ion battery energy storage. This test represents a significant validation of the technology's applicability in the field of long-duration energy storage, particularly in flow battery applications.
NR Electric will continue to focus on core technologies for grid-forming energy storage, deepen cooperation with industry partners, and contribute to the construction of a safer, more stable, and more flexible new power system.
