A Study of a Photovoltaic Production Line Controlled with a PI Corrector

Abstract

This article presents a study and simulation of a photovoltaic production line. It consists of PV panels sized to recover the maximum power output. These photovoltaic panels power a DC-DC boost converter that produces a DC output voltage greater than the input voltage. The output of the DC-DC boost converter is influenced by the variation of temperature and solar irradiance. Thus, a PI control is used to stabilize its value. The boost converter supplies a DC-AC converter that converts the DC input voltage to AC voltage. The control of the inverter applied is a sinusoidal pulse width modulation. An LC filter is connected to the output of the inverter to eliminate some unwanted frequency components. This system is simulated under the Simulink matlab software.
