A new approach to analysis and simulation of flywheel energy storage system

To power electronic gadgets, hybrid energy storage systems have emerged as a worldwide option during the last several years. Many of the benefits of energy storage systems may be correctly coupled with these technologies, and a sufficient supply of energy for certain applications can be achieved as a result of doing so. Today's world demands an ever-increasing amount of energy, but it demands that this energy be cleaner than that generated by the existing generating systems. Distributed generating technologies and especially renewable energy sources have grown in popularity because of this necessity. Flywheel Energy Storage System (FESS) is one of the emerging technology to store energy and supply to the grid using permanent magnet synchronous machine (PMSM). Electromagnetic induction is the primary source of mechanical power in a permanent magnet synchronous machine. The machine speed will fluctuate and influence power usage if there are sudden changes in loading and unloading. A PMSM's speed stability can be enhanced by using a flywheel with varying moments of inertia, which is shown in this paper. The moment of inertia of the variable inertia flywheel can fluctuate if there is an imbalance between the induction motor's output torque and the load torque. As an internal feedback loop, it uses the motor's angular acceleration as input and lessens the load's rapid impact using the variable inertia flywheel. The reduced sensitivity of the motor to the loading impact is confirmed by SIMULINK simulation results under sudden loading and unloading conditions. Variable flywheel inertia reduces power consumption and provides a smoother response and better anti-disturbance capability for PMSM motor systems of FESS.
