Abstract：Adjustable speed pumped storage hydropower plants can effectively compensate the power fluctuations resulted from the renewable energy generation. As a modular cascaded direct AC to AC multilevel converter, the modular multilevel matrix converter (M3C) is a promising topology to meet the super high-voltage and high-power demand of hydraulic pumped storage plants. To improve the frequency regulation capability and the system operation efficiency, the paper proposed a M3C based hydraulic pumped storage system. A 10kW M3C prototype with 27 modules had been established to verify the full-frequency operation of the M3C under pump and generator operation.
