Functional Coding of Maximum Power Point Tracking by Using Perturb and Observe Method in MATLAB for PV System

Abstract

Implementation of the solar system is nowadays very popular due to less availability and high cost of non renewable fuels. In this work, modelling of the solar panel along with Maximum Power Point Tracking (MPPT) is performed. MPPT is used to make the system more efficient. To gain this Perturb and Observe method is used to obtain the constant DC voltage at the maximum power. In this paper, constant DC voltage is achieved for the different solar irradiations. In this proposed work at 600 W/m², 800 W/m², 1000 W/m² irradiations, the results are obtained.

Keywords: MPPT, PV cell, irradiation, voltage at maximum power
