Abstract
In this paper, we consider the problem of controlling a single-phase grid-connected photovoltaic system using the backstepping technique and an adaptive observer. The conversion system includes a PV panel, a DC-DC Boost converter, a DC-AC half bridge inverter connected to the grid via an LCL filter. This work aims at achieving threefold control objectives: i) extracting the maximum available power ii) guaranteeing a unitary power factor (UPF) by forcing the grid current to be sinusoidal and in phase with the electric network voltage, iii) regulating the DC link voltage to a desired references value. The performance of the proposed regulator is evaluated through numerical simulation using MATLAB/SIMULINK environment.
