Abstract

The flywheel energy storage (FES) system presented in this paper is composed of four parts: the flywheel, the bearing, the motor/generator and the power converter. The control methods and strategy of the FES system in power network are introduced in detail. During the storage period and generating times, the waveform of the power converter output currents is controlled to be sinusoidal by using sinusoidal pulse width modulation (SPWM) control method, so the efficiency of the energy conversion is high and the torque ripple of the motor/generator is minimized. The control methods of starting and operating large moment of inertia of the flywheel are simulated and studied for the power converter. The latest experimental results of the FES system are introduced, and the control validity is verified through these results.
