Charging and discharging controller designing and modeling of Flywheel Battery based on SIMULINK

As a new style of mechanical battery with lots of advantages, Flywheel battery nowadays gets more and more attentions. It realizes power conversion through efficient charging and discharging. One powerelectric control system based on id =0 control scheme, for flywheel’s charging and discharging, is presented in this paper; meanwhile the corresponding whole continuous charging and discharging simulation model of flywheel battery is established by Matlab, and it works in the simulation experiment. The simulation result show that the highspeed flywheel achieves stability quickly with good dynamic characteristics in charging, and in discharging its speed declines stably and output direct current is in expectation. Thus this control system has been proved correct, which demonstration flywheel battery’s viability and efficiency.
