This paper focuses on the use of model predictive control (MPC) to control a DC/DC boost converter in order to regulate the PV power. When integrated with the grid, the PV system must deliver maximum power most of the time; however, if a voltage sag occurs, new grid codes demand that the control system should limit the PV power generated to avoid over current conditions and, consequently, a grid disconnection...
This paper focuses on the study of a two-stage, multi-string photovoltaic (PV) system connected by a common DC bus to a centralized inverter, interfaced with a utility grid. The distribution network model, load model and DC bus model are used for simulation. PV system exhibits non-linear v-i characteristics and an intermediate boost converter is employed to operate the PV array at its maximum power...
