Design of Grid Connected Photovoltaic System Employing Increamental Conductance MPPT Algotithm

Abstract

This paper is mainly to develop a grid-connected photovoltaic simulation system with Incremental conductance maximum power point tracking (MPPT) function using MATLAB. By this simulation we predict the behaviors of the real photovoltaic system. A PV model is first developed and then combined with an MPPT algorithm and a DC-DC converter, in order to verify the correctness of MPPT controller. This system is followed by DC-AC inverter and the output is connected to the grid. The results are output voltage and current of PV model, output AC voltage, current and real power to the system.
