  Grid-forming Energy Storage Converter (PCS) is a new-generation energy storage conversion equipment independently developed by CRRC Qingdao Sifang Rolling Stock Research Institute Co., Ltd. leveraging its core technical expertise in rail transit power electronics, featuring active voltage support capability.

  Adopting a voltage-source grid-forming control architecture, the product can independently establish stable voltage and frequency references, realize seamless switching between grid-connected and off-grid operating modes as well as system black start, and break through the bottleneck of traditional grid-following PCS relying on the bulk power grid.

  The product is deeply adaptable to a wide range of application scenarios, including wind-solar-storage integrated power stations, virtual power plants (VPPs), standalone microgrids, industrial and commercial peak shaving, and grid-side frequency and voltage regulation. It effectively addresses industry pain points caused by high-penetration new energy grid integration, such as insufficient grid inertia, low voltage/frequency stability margin, and poor power supply reliability, supporting the construction of the new power system and driving the upgrading of the energy storage industry towards high reliability, high intelligence, and high adaptability.
