电化学储能在330MW火电机组辅助AGC调频中的应用与分析OA

By integrating an electrochemical energy storage system,a combined thermal-storage frequency regulation system can be established for thermal power units.This fully leverages the advantages of electrochemical energy storage—namely,its rapid response and high regulation accuracy—to effectively enhance the overall Automatic Generation Control(AGC)frequency regulation performance of thermal power units.Taking a 330 MW thermal power unit as an example,the practical application results of electrochemical energy storage assisting AGC frequency regulation are analysed.It is indicated by the results that the unit's frequency regulation performance indicators were significantly improved by the commissioning of the energy storage system.Furthermore,in response to power oscillations that occurred during the initial phase of system operation,measures such as optimising control strategies and restricting operating modes effectively ensured the safe and stable operation of the power grid,the unit and the energy storage system,whilst further enhancing the performance of the combined frequency regulation system.
