The flywheel energy storage system (FESS) has a large capacity, high energy conversion rate, high instantaneous power, and high-frequency charge and discharge characteristics. It has broad application prospects in grid frequency modulation, uninterrupted power supply, and kinetic energy recovery and reuse.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
Based on MATLAB/Simulink simulation, the role and effect of secondary frequency modulation assisted by Flywheel Energy Storage System (FESS) in regional power grid with certain wind power penetration rates are studied.
