ABSTRACT:
|
The photovoltaic system is
one of the renewable energy device, which directly converts solar radiation
into electricity. The I-V characteristics of PV system are nonlinear in
nature and under variable Irradiance and temperature, PV system has a single
operating point where the power output is maximum, known as Maximum Power
Point (MPP) and the point varies on changes in atmospheric conditions and
electrical load. Maximum Power Point Tracker (MPPT) is used to track MPP of
solar PV system for maximum efficiency operation. The various MPPT techniques
together with implementation are reported in literature. In order to choose
the best technique based upon the requirements, comprehensive and comparative
study should be available. The aim of this paper is to present a
comprehensive review of various MPPT techniques for uniform insolation and
partial shading conditions. Furthermore, the comparison of practically
accepted and widely used techniques has been made based on features, such as
control strategy, type of circuitry, number of control variables and cost.
This review work provides a quick analysis and design help for PV systems.

CONCLUSION:
The prominent techniques of MPPT are
discussed in this paper. It may be used as tutorial material on solar MPPT.
Also, an attempt has been made to describe the important GMPPT techniques with
sufficient details. A comprehensive comparative analysis has been contributed
in this paper considering performance, cost, complexity of circuit and other
parameters of MPPT. The results of this analysis will be helpful for proper
selection of MPPT method. The generated power performance through few MPPT
controllers has been illustrated with the help of simulation excercise. This
also provides better understanding through numerical comparison. This review
work has also presented a brief analysis and comparison of MPPT techniques for
partial shading conditions. This paper may be useful for solar PV system
manufacturer and solar inverter designer.
