Long-length horizons dynamic matrix predictive control for a MMC inverter Article uri icon


  • This paper proposes an indirect model predictive control (I-MPC) strategy that allows considering long-length horizons to control a modular multilevel converter (MMC) working as an inverter, where such a MMC has the purpose to transfer bidirectionally active power to the grid, and simultaneously compensate reactive power. In the proposed scheme the dynamic matrix control (DMC) technique is adopted to generate the direct power control (DPC), where new power references are computed by taking into account the system behavior from a detailed circuit or model. In addition, the DMC allows to present a hybrid modulation structure that involves a sinusoidal pulse width modulation (SPWM) together with a voltage capacitor balance strategy. Finally, with the aim to illustrate the feasibility of controlling highly redundant converters, the MMC, the hybrid modulation technique and the control scheme are tested on a real-time simulation environment OPAL-RT®. © 2018
