Connected MPPT Based Photovoltaic System
Author Name : Sibasish Panda, Dr Anup

Synopsis :
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.
