Kehua Data: Innovations in Grid-forming Energy Storage Empower New Power System Construction
As the energy storage industry continues to thrive, grid-forming energy storage has emerged as a focal point due to its exceptional performance and wide-ranging application potential. Kehua Data, a global leader in energy storage system solutions, draws upon its profound technical expertise and innovative spirit to provide new insights and directions for the advancement of the energy storage sector.
On April 11, during the 13th International Energy Storage Summit sub-forum, Kehua Data delivered an impressive presentation titled “Exploration of Grid-forming Technology for Large-scale Energy Storage Stations”. The discussion included a comprehensive analysis of the current state of the industry, advancements in grid-forming energy storage technology, and its mission. The company highlighted its advanced liquid-cooled cluster PCS system solutions and numerous successful project implementations, garnering high recognition from experts and industry professionals in attendance.
Kehua Data noted that with a high proportion of clean energy being integrated into the grid, the system’s inertia decreases, posing challenges to grid stability. Grid-forming technology enables energy storage systems to simulate the functions of synchronous generators, actively responding to, supporting, and enhancing the grid’s inertia, frequency, voltage, and short-circuit current, thereby providing robust support for the new power system and effectively addressing grid adaptability issues.
The maturity of grid-forming energy storage technology is increasing, with its applications expanding significantly and its potential being vast. In the microgrid support domain, it is adaptable for various sizes of microgrids in off-grid areas, meeting the power supply needs of high-altitude and other special regions to ensure microgrid reliability. In terms of black start for the grid, it can serve as a regional black-start power source, enhancing the grid’s emergency capabilities and facilitating rapid recovery of large power grids. For grid stability support, it cleverly addresses local grid stability challenges, enhancing the transmission and receiving capabilities of key plants, and providing solid voltage support to ensure stable and reliable power supply.
In the field of grid-forming energy storage, Kehua Data is committed to continuous technological innovation and product upgrades. The latest liquid-cooled cluster PCS energy storage solution, unveiled during the summit, not only enhances the existing product line and broadens application scenarios but also elevates Kehua Data’s innovation in energy storage technology to new heights. The next-generation liquid-cooled cluster management PCS achieves ultra-high power density, reducing costs while laying the foundation for the efficient operation of energy storage devices.
In terms of grid-forming performance, the new product boasts comprehensive grid-forming support capabilities, demonstrating outstanding performance. It can operate stably within complex grid environments, even achieving reliable operation under three times overload. It features millisecond-level power response and microsecond-level voltage build-up capabilities, along with adaptive wide short-circuit ratios, multi-cooperative group black start, and domain-level black start functionalities.
For thermal management, the new product employs a fully liquid-cooled design with patented cooling plate technology, akin to providing the equipment with a powerful “air conditioner.” Even at high temperatures of 50°C, the PCS maintains stable operation without derating, significantly enhancing device stability and reliability. This upgrade also extends the system’s lifespan by over 25%.
In terms of structural protection, the new product features IP66+C5 composite corrosion-resistant protection and has passed various rigorous environmental tests, ensuring it can withstand rain, snow, sand, and high-corrosion environments effortlessly. Furthermore, the product’s adaptability is highly flexible, compatible with various cell sizes and capacities, catering to both 2-hour and 4-hour application scenarios, thus improving system availability.
This innovative achievement not only demonstrates Kehua Data’s deep expertise in energy storage technology but also injects new vitality into the development of grid-forming energy storage technology, leading the industry’s direction. With 37 years of solid foundation in power electronics technology and the experience of developing over 4,000 new energy projects, Kehua Data holds a competitive advantage in large-scale, long-duration grid-forming energy storage applications.
Since 2007, Kehua Data has delivered over 1GW of grid-forming energy storage systems. In exploring diverse regional grid-forming projects, the company continually expands its application fields, leaving footprints in various scenarios from microgrid applications to strong overload black start, and from islands and remote areas to weak and strong grids in new energy regions.
In 2024, Kehua Data became the first company in China to pass the comprehensive grid-forming verification test conducted by the China Electric Power Research Institute, marking its leading position in the industry. In 2025, the company delivered a 300MW/1200MWh grid-forming energy storage project in Xinjiang and a 60MW/300MWh independent grid-forming energy storage project in the high-altitude region of Tibet, providing full-capacity grid-forming energy storage system solutions and setting a benchmark for GWh-level grid-forming energy storage and ultra-high-altitude energy storage stations.
As a pioneering force in the grid-forming energy storage field, Kehua Data significantly contributes to the stable operation of the grid and the widespread use of clean energy through its exceptional technological strength and extensive practical experience. Moving forward on the path of energy transition, Kehua Data will continue to strive for innovation and exploration, contributing to the safe and sustainable development of the energy storage industry and leading the sector to new heights.
