Smart Switching Algorithm Between IC and PO Algorithms for Grid-Connected PV System

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 435)

Abstract

As we know that n number of methods are available to increase the output power to the level of maximum power from the PV cells, but among all of those methods there are two methods which are majority in use which are P and O method and IC methods, in this paper we have analysed each method under less step size and more step size vice versa. As the result says that the IC method tracks the maximum power point efficiently within short span of time with reduced ripples when its step size is less, in the same way the P and O method is able track the maximum level of power more efficiently within short span of time with reduced ripples when its step size is more. Hence, in this paper we have developed a new algorithm which can smartly switch over the technology between P and O and IC methods according to the step size which is demanded by the system so as to improve the efficiency, cut the ripples and improve the power quality when the output power generated from PV is connected to the utility grid. The output from this technique is utilized to change the width of the pulse of Zeta (DC-DC) converter which converts the variable DC to fixed DC to make the output compatible to inverter circuit which is compatible to connect it directly to the commercial grid.
