摘要：

The modular multilevel converter (MMC) with cascaded full bridge cells is available for AC/AC transmission system without transformers in high voltage line. The MMC is focused on as the transformer-less converter to realize light weight and downsizing and the multi-level waveforms to obtain less distorted output. When it is interconnected with power line, it is possible to control the active power flow in order to supply or charge the power in the line. The Hexagonal MMC (H-MMC) for 3-phase AC-AC conversion system with energy storage is investigated. The H-MMC has six arm modules with floating capacitors. In addition, the circuit has energy storage system such as the battery or the super capacitor to compensate surplus or shortage power between input and output. The control theory of H-MMC with the energy storage is explained and the operation is performed in simulation. Effectiveness of the proposed control method in some typical conditions is verified.
