Adaptive P&O MPPT Method Using Zeta Converter for Solar PV Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
This paper implements an Adaptive Perturb and Observe (P&O) Maximum Power point tracking (MPPT) method using Zeta converter (Dc-Dc converter) for photovoltaic systems. In this proposed method current perturbation is considered to speed up the tracking performance under suddenly changing environmental conditions using Peak Current Control technique which eliminates the PI controller. The Adaptive P&O MPPT controller controls the duty cycle of the Zeta converter, which finally controls the PMDC motor used for solar PV application. The proposed method is implemented in MATLAB/SIMULINK simulation software and the results validate that the proposed system has faster dynamics, improved stability compared to Conventional P&O method and capable of tracking Maximum Power Point (MPP) accurately and rapidly under suddenly changing environmental conditions.
