Abstract To address frequency fluctuation challenges caused by high-penetration renewable energy integration, this study proposes a hybrid frequency regulation architecture combining aqueous organic redox flow batteries (AORFBs) with coal-fired power units. Leveraging the redox mechanisms of water-soluble organic electrolytes, AORFBs exhibit millisecond-level dynamic response, long cycle life, and inherent safety, effectively compensating for the thermal inertia delay of coal-fired units while reducing mechanical wear and enhancing regulation accuracy. By optimizing key technologies such as high-stability organic electrolyte synthesis and long-life ion membrane preparation, and implementing collaborative control strategies, the demonstration project verifies the effectiveness of the AORFB system in improving frequency regulation performance. Results demonstrate that coordinated control strategies achieve efficient thermal-storage synergy, with scalability potential to optimize lifecycle costs. This system provides a secure and reliable frequency regulation solution for future power grids, advancing energy transition through technological innovation.
