Abstract

The energy storage device is vital to the smooth operation of the capacitor power and optimize the power quality. A hybrid energy storage capacitor control system based on the microgrid is designed. The battery pack and the super capacitor in the system hardware are connected in parallel through the DC/DC converter. When the mixed storage energy of the microgrid is abnormal, the F28M35 central control chip collects the data of the battery pack and the Super capacitor, completing the charge and discharge control of super capacitors and batteries. After analyzing the detailed information of the super capacitor, the control strategy of parallel bidirectional DC/DC converter is adopted to achieve the hybrid capacitance control of the microgrid. The experimental results show that the average capacitance stability of the system is 99.99 %, and the convergence speed is fast. After
controlling 7 ms, the active power of the microgrid tends to be stable, and the capacitance power of the microgrid can be guaranteed to run smoothly.
