摘要：
This paper shows the performance of a LCL-type grid-connected three-phase H-bridge neutral-point-clamped converter photovoltaic inverter controlled with conventional Finite Control Set Model Predictive Control scheme. The main issue with this application is the potential resonance between the converter and the grid side, which must be fully avoided. This control problem is addressed by including a simplified active damping technique based on series and parallel virtual resistors to the conventional predictive scheme. Furthermore, current reference tracking for active and reactive power injected to the grid are achieved.
