[0002] In power systems, especially power plants, energy storage technology is increasingly used, especially in auxiliary frequency regulation. Energy storage devices can quickly respond to changes in grid frequency and improve the stability and reliability of the system. The development of this technology not only helps to optimize energy utilization efficiency, but also can provide backup power in emergency situations to ensure the safety of power supply. With the large-scale access of renewable energy, the importance of energy storage technology has become more prominent and has become an indispensable part of modern power systems. In order to realize the auxiliary frequency regulation function of power plant energy storage, there are currently many commonly used solutions. Among them, one of the common methods is to use large-capacity battery packs as energy storage units and manage the charging and discharging process through a central control system. In addition, there are energy storage systems based on supercapacitors, which have the characteristics of high power density and long life and are suitable for frequent charging and discharging needs. In addition, flywheel energy storage systems are gradually being used in power frequency regulation. The system stores kinetic energy through a high-speed rotating flywheel and then converts it into electrical energy through a generator. It has the advantages of high efficiency and fast response.
