To address the pressing demand for grid frequency stability under high-proportion renewable energy integration and mitigate the slow frequency regulation response of thermal power units, aqueous organic redox flow batteries (AORFBs) have emerged as a viable technical solution for frequency regulation scenarios due to their advantages of long cycle life and low self-discharge rate.
A thermal-storage combined AGC frequency regulation technology utilizing AORFBs for energy storage is presented. The fundamental principles of coordinated thermal-storage technology and AORFBs are elaborated, the core performance parameters of flow batteries are tested, a frequency regulation control strategy for AORFBs-assisted thermal power units is proposed, and this approach is applied to the 200 kW/400 kW·h thermal-storage combined frequency regulation demonstration project at Luoyuan Power Plant.
Operational data and analytical testing demonstrate that AORFBs exhibit rapid regulation and precise output response characteristics, thereby enhancing the frequency regulation capability of the combined system.
Applying AORFBs to thermal power frequency regulation is feasible.
