Analysis and Performance Evaluation of P and Ompptfor Pvconnecteddc-Dcboost Converter

Abstract

The I-V characteristics of solar cell are affected due to solar irradiation and local temperature conditions. The solar cell array output power varies due to variations in radiation and cell temperature. Various maximum power point tracking (MPPT)algorithms are developed for extraction of maximum powerfrom a solar array when it operates at MPP which varies continuously whenever there is change in solar panels temperature or irradiance. The solar cell array is integrated with intermediate converter to utilize extracted maximum power from the solar panel. This integrated system operated at high efficiency and the low operating cost. This paper discusses about Perturb & observes algorithm implementation by considering only voltage profile of solar cell module. The integrated system comprising of solar array, boost converter along with MPPT is simulated using MATLAB/SIMULINK tool.
