JEE_V9_N4_RP5 Bal Mukund Sharma Kuldeep Sahay Journal on Electrical Engineering 2230 – 7176 9 4 37 46 Maximum Power Point Tracking (MPPT), Photovoltaic Array, Buck Converter and Perturb and Observe Algorithm This study presents a new kind of Maximum Power Point Tracking algorithm based on perturb and observe algorithm. A generalized photovoltaic array simulation model in Matlab/Simulink environment is developed and presented in this paper. The model includes PV module and array for easy use on simulation platform. The proposed model is designed with a user-friendly icon and a dialog box like simulink block libraries. Considering the effect of solar irradiance and temperature changes, the output current and voltage of PV modules are simulated and optimized using this model. A perturb and observe algorithm based maximum power point tracker is also developed using the presented model in Matlab/Simulink. It can successfully track the maximum power point more accurately and quicker than other conventional method based controller in these situations. The general model was implemented on Matlab scrip file, and accepts irradiance and temperature as variable parameters and outputs the I-V characteristic. A particular typical 800W solar panel was used for model evaluation and results. April - June 2016 Copyright © 2016 i-manager publications.
