FCS-MPC for grid-tied three-phase three-level NPC inverter with experimental validation

Distributed power generation systems (DPGS) tend to increase their capacities of production of electricity. Multilevel converters are considered today among the most suitable topologies for DPGS connected medium voltage grids. On the other hand, Finite-Control-Set Model Predictive Control (FSC-MPC) has become in the last decade a promising control method thanks to its fast dynamic response and robustness. In this paper, this control method is applied on a grid-tied three-phase three-level neutral point clamped (NPC) inverter. The main objectives behind the proposed method are: performs a perfecto control of the powers exchanged with the grid active and reactive powers in steady state operation, and avoid the overcurrent due to the grid faults. The effectiveness of the proposed FSC-MPC applied on the NPC converter is validated with numerical simulations and experimental tests.
