To address the problems of slow response and low ramping rate of traditional thermal power units in peak and frequency regulation
this study selects flywheel energy storage as the research object by comparing the technical performance and economics of mainstream energy storage systems. Using the energy storage system auxiliary frequency regulation technology
the rated power
capacity
frequency regulation effect and economic benefits of flywheel energy storage are calculated and analyzed. The research shows that relying on its technical advantages of fast response and long cycle life
the flywheel energy storage system can significantly improve the frequency regulation performance of thermal power units and bring considerable economic benefits
indicating that it has important application value and promotion potential in the flexibility transformation of thermal power units.
