Predictive Direct Power Control of a Grid Connected Three-Phase Voltage Source Inverter for Photovoltaic Systems
TLDR
In this article, the control of a three-phase voltage source inverter (VSI) for a grid-connected photovoltaic (PV) system is discussed.Abstract:
This paper deals with the control of a three-phase voltage source inverter (VSI) for a grid-connected photovoltaic (PV) system. The direct power control (DPC) is combined with a predictive approach for selecting the optimal inverter switching states. This optimal selection is carried out by minimizing a suitable cost function. Moreover, in order to extract the maximum available power from the PV generator, a fuzzy logic maximum power point tracking (MPPT) controller is applied to a DC-DC quadratic boost converter acting as an interface between the PV generator and the inverter. Modeling and simulation of the system were performed by using Matlab/Simulink softwareread more
