Power Improvement of Partial Shaded Photovoltaic System Using Water Swirl Arrangement Method

The phenomenon of the partial shading is major cause which affects the operation of the PV system. The non uniform irradiation mainly caused due to towers, passing of clouds, falling of trees, etc. This becomes the reason to power reduction and mismatch loss. In this developed arrangement method, a new reconfiguration method is developed to enhance the power of the PV system which follows the Water Swirl (WS) pattern. The operation of PV system with minimum mismatch loss of PV array using shaded dispersion method is allowed. For array formation of developed method, the equations with constraints are expressed. Simulation of
$\mathbf{9}\times \mathbf{9}$
Photovoltaic arrays is simulated in MATLAB/Simulink and output analysis has been validated. The comparison is made between mismatch loss generation under non-uniform pattern and power improvement with various arrangement methods. The developed arrangement method is good and well than total cross tied and series-parallel patterns methods. For assumed system mismatch losses are minimal and power output is improved using shade dispersion.
