| Abstract: | This article proposes a battery‐based hybrid power flow controller (B‐HPFC), offering enhanced flexibility for power flow regulation and energy storage. First, the structure of B‐HPFC is given, where the cascaded H‐Bridge (CHB) is integrated with the phase‐shifting transformer (PST). The batteries are connected to the modules of CHB. Doing so, the power flow can be adjusted by tuning the PST and CHB while the batteries can be charged or discharged by tuning CHB. Then, the hierarchical control method is given. The power flow control strategy operates as the outer loop, and the battery control strategy operates as the inner loop. Finally, the proposed structure and control method are verified by the hardware in the loop prototype. The results show that the power flow can be controlled smoothly while the SOC of batteries can be balanced. [ABSTRACT FROM AUTHOR] |
