Summary: | This work deals with a grid-tied single-phase photovoltaic (PV) Cascaded H-Bridge (CHB) inverter implementing a distributed battery energy storage system (BESS) able to output a constant active power in scheduled time intervals. The control strategy is based on a hybrid modulation technique exploiting a sorting algorithm performed on batteries' state-of-charge (SoC). The aim is to prove the reliability of the system after recovering from grid trip, which causes unbalance among the batteries' SoC. Additionally, the proposed inverter is investigated considering a deep mismatch among the PV generators. Numerical analyses are performed on a 19-level CHB inverter in PLECS environment to show the effectiveness of the proposed control strategy. |
