High Power Density: Flywheel energy storage systems can store a large amount of energy in a small space, making them suitable for applications where space is limited. Fast Response Time: Flywheel energy storage systems can respond quickly to changes in demand or supply.
Fig. 7.8 shows the integration of the flywheel energy storage system with the grid. In this method the stored energy is transferred to the grid by a generator, alternative current (AC)/direct current (DC) rectifier circuit, and DC/AC inverter circuit. Figure 7.8. Flywheel energy storage system topology.
In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California. The system was part of a wind power and flywheel demonstration project being carried out for the California Energy Commission.
While many papers compare different ESS technologies, only a few research, studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the
