[Abstract]:Firstly, the basic principle of bidirectional energy converter in flywheel energy storage system is analyzed, and then the optimal charge and discharge control strategy of flywheel energy storage system is put forward, including the improved compound control strategy during charging and the comprehensive optimization weak magnetic control strategy during discharge, which solves the limitations of the application of traditional control strategy, and gives the control block diagram of the system. The simulation results and experimental results show that the proposed charging control strategy is suitable for the flywheel working mode, the constant torque control is switched quickly to the constant power control, and the proposed discharge control strategy can stabilize the DC bus voltage in the full power range, which is effective and feasible.
