Abstract

The presented work in this paper deals with various step sizes used in incremental conductance (INC) related to the maximum power point tracking (MPPT) technique. In the solar photovoltaic system, the variable step size selection method for INC is proposed and compared. The MATLAB/Simulink and hardware setup are used for assessing and analyzing step size methods. The variable step size (DVS), fixed step size (DFS) are comprehensively studied and compared. This DVS method is having a lower ON delay time (Td <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ON</sub> ) as 148 msec as regard to 164 msec in the DFS method. On the other hand, the lowest peak-peak oscillations in load current as 0.04 amp for DVS as compared to 0.5A for the DFS method, lower peak current as 1.96A for DVS as compare to 2.37A for the DFS method. In this way, the performance of the DVS method is found superior as it is analyzed and compared with the DFS algorithm.

Summary

Introduction

Researchers emphasize the use of nonconventional resources for fulfilling the energy requirement due to the harmful effects produced by non-renewable energy resources. Human beings always tried to change their environment, which resulted in wreckage and desolation. The non-conventional or alternative fuel sources including the wind, fuel cell, solar etc. Non-conventional fuel resources possess the massive potential for enhancing the capacity of conventional electric power generation. There will be significant growth in the field of alternative fuel sources. With the advancement in technological systems, a reduction in cost and size can be figured out from the process of generation to transmission of renewable energy [1]
