N2 - This paper proposed a Z-type modular multilevel converter (Z-MMC) based static synchronous compensator (STATCOM) with capacitor voltage self-balancing ability. With series connection of Z-type submodules, the Z-MMC can generate stepped output voltage waveform with very small harmonic contents. The voltage rating of the Z-MMC can be easily scaled up by adding new ZT-SMs, which makes it suitable for medium/high voltage applications. Different from the traditional modular multilevel converter (MMC) that requires complex voltage balancing control for each capacitor, the capacitor voltages of the Z-MMC are self-balanced. Therefore, the control of the Z-MMC based STATCOM is simplified compared with the MMC based STATCOM. Simulation results confirm the effectiveness of the proposed Z-MMC based STATCOM.
