Simulation of Flywheel Energy Storage System Controls

design, the flywheel operating speed will be between 20 000 (min.) and 60 000 (max.) rpm. Since the inertial energy stored in a flywheel varies as the square of its rpm, it can discharge 90 percent of its maximum stored energy from maximum to minimum speed limits. The flywheel rotational inertia constant selection is based on energy storage

Distributed fixed-time cooperative control for flywheel energy storage

This paper studies the cooperative control problem of flywheel energy storage matrix systems (FESMS). The aim of the cooperative control is to achieve two objectives: the output power of the flywheel energy storage systems (FESSs) should meet the reference power requirement, and the state of FESSs must meet the relative state-of-energy (SOE) variation
