| Résumé : |
Partial shading can dramatically decrease PV array power output as wellas complicate operation by causing multiple peak exhibitions in the power voltage(P-V) characteristic curve.
These problems depend not only on the shading area but also and much more significantly on the shading pattern .
In this work three new physical PV array arrangements to mitigate partial shading effects, are proposed .
These arrangements are based on maximizing the distance between adjacent PV modules within a PV array, while rearranging modules to be in different rows and columns without changing the electrical connections .
This allows redistribution of the shading patterns over the entire array .
This result in a power dissipation minimization of the protection diodes in addition to maximizing the power output and eliminating multi peaks.
Simulations are presented to assess the proposed physical PV array arrangements .
This assessment is done through performance comparisons for various PV array configurations and arrangements under different shading patterns and scenarios .
The new physical PV array arrangements yields the highest performance in terms of power output and eliminates the problem of local multi peaks in the P-V array characteristic curve . |
