Abstract: The flywheel energy storage has little need for the circumstance, and it has a low impact on the environment. In addition, the charging depth of the flywheel energy storage is simple, and the prediction of the health condition is basic.This paper constructed a single-machine grid-connected simulation model of the flywheel energy storage system in MATLAB/Simulink based on the mathematical model of a back-to-back dual PWM inverter and permanent magnet synchronous motor. By analyzing the simulation results under complex working conditions, this research found that the system has a low ability of anti-disturbance and severe problems with DC bus voltage fluctuations.This paper proposed an optimized dual-loop feedforward coordinated control strategy for back-to-back inverters by theoretical analysis. This method added a capacitor current control loop to the structure of the inner current control of the traditional grid-side converter. Moreover,it used the estimated value of the load current and the grid voltage as feedforward terms. It verifies the effectiveness of the control strategy through simulation analysis. In addition, this research proves it could realize the integrated control of the converters on both sides. All in all,it improves the self-disturbance immunity and dynamic performance of the whole flywheel energy storage system.
Key words: back-to-back inverter; flywheel energy storage system; vector control; feedforward control; load disturbance; pulse-width modulation
