Decoupled Active and Reactive Power Control for Asymmetric Cascade Multilevel Energy Storage System

For the asymmetric cascade multi-level hybrid energy storage system based on battery and capacitor, a control method based on active/reactive decoupling is proposed. The H-bridge output voltage is decomposed into an active component parallel to the grid current and a reactive component perpendicular to the grid current. The active voltage is distributed on demand, one for DC capacitor regulation and the other for battery and grid interaction. The reactive voltage is distributed at the maximum allowable value, ensuring that the reactive component is fully distributed to each module without overmodulation. The proposed control method realizes the distribution of power between links, and ensures the stable operation of the system. Finally, the correctness and effectiveness of the method are verified by simulation.
