Modeling and Simulation of a MPC Based Grid-Tied PVDG system

Roshan Pradhan, Aurobinda Panda

Abstract


This paper presents the modelling of a grid-tied photovoltaic distributed generation (PVDG) system with model predictive control (MPC) implemented for maximum power point tracking (MPPT) of PV arrays and inverter control for achieving multiple control objectives such as dc-link voltage control, active and reactive power flow and power quality control. A dc-dc boost converter has been used for adjusting the operating point of the PV array for MPPT and a single phase bridge inverter for grid integration. The performance evaluation of the PVDG system model has been done using MATLAB simulations. Model predictive control provides a faster MPPT response under rapidly changing atmospheric conditions and an effective inverter control strategy with power quality enhancement and improved efficiency.
