Model Predictive Control for a Modular Multiport Solid-State Transformer

This paper proposes a model predictive control (MPC) strategy for a modular multiport solid-state transformer (SST). The proposed system enables the interconnection of low- and high-voltage systems including electric vehicles, renewable energy sources and DC grids. The adopted SST topology uses a modular multilevel converter (MMC) followed by input-series output-parallel dual active bridge (ISOP DAB) converters. The presented simulation results demonstrate the effectiveness of the proposed MPC-based SST controller.
