Comparative Analysis of Standalone SPV System with LUT and P&O MPPT Algorithm
Abstract
PhotoVoltaic (PV) power production gathers greater attention recently while the main problems associated with the PV cells are lower power transformation efficiency, high rate and nonlinear nature of output power. Inorder to ensure the working of PV system at its Maximum Power Point(MPP), Maximum Power Point Tracking (MPPT) method employed with power converter is utilised for harnessing maximum accessible power from source to load irrespective of any changes in environmental conditions. In this paper, a relative study is made for a standalone system with Look Up Table (LUT) and Perturb & Observe (P&O) MPPT controllers. Flat and linear interpolation LUT techniques are also analysed. MATLAB/SIMULINK based simulation is done and results for tracking rate, steady state fluctuations and efficiency are analysed.
