A Typical Review on Static Reconfiguration Strategies in Photovoltaic Array Under Non-Uniform Shading Conditions
Maximum power extraction from the photovoltaic (PV) system plays a critical role in increasing efficiency during partial shading conditions (PSCs). It directly reduces the output power of the PV array. There are different factors
such as bypass diode configuration
array size
array configuration
shade intensity
environmental conditions etc.
affecting the performance of the solar photovoltaic panel. Furthermore
series (S)
parallel (P)
series-parallel (SP)
total-cross-tied (TCT)
bridge-linked (BL)
and honey-comb (HC)
etc.
are the various configurations to deal with the mentioned issues. But these PV array configurations also have drawbacks
such as low dispersion factor
mismatch losses
and line losses under partial shading conditions. To overcome these issues
the reconfiguration of the PV array is one of the effective approaches. A comprehensive study of literature shows that PV modules are connected under different reconfigured schemes namely Sudoku
Optimal Sudoku
Magic square
zigzag
Skyscraper
etc. In this paper
a comprehensive review is performed to highlight the advantages and limitations of each scheme. This study can be used to address the advancement in this area since some parameter comparisons are made at the end of every technique
which might be a prominent base-rule for picking the most promising reconfiguration technique for further research.
