This paper explores a utility-scale photovoltaic (PV) plant configuration based on a dc–dc stage interfaced directly to a modular multilevel converter (MMC) used for an HVdc power station. Since PV systems are dc by nature, the proposed solution has several advantages, such as full dc operation and step-up transformers avoidance with modular and reliable configuration. The contributions of this paper...
Model predictive control (MPC) has been successfully applied to several power converters topologies, mainly because of the finite set of inputs which are given by the available switching states of these devices. However, MPC could not directly control the DC-link voltage in active-front-end(AFE) rectifiers, because they feature a non minimum phase behavior that produces an initial inverse dynamic...
