Abstract

This paper presents the simulation model of a 3.5 kW PV array followed by a boost converter, which boost up the output voltage of the PV array. Maximum Power Point Tracking (MPPT) can effectively improve the solar energy conversion efficiency of PV array, in this paper Perturb- and – Observe (P&O) algorithm has been used to achieve this function. Grid connected PV system needs a three phase inverter for synchronization. The inverter control system modeling has been carried out in Matlab/Simulink 2010 environment with the aids of the proportional-integral controllers, sinusoidal vectored pulse width modulation technique and park transformation. Phase Locked Loop (PLL) is used to lock the grid frequency and phase. Finally different types of AC faults are created on the grid side and Total Harmonic Distortion (THD) is calculated in each of the case.
