A Reconfigurable PV Architecture Based on New Irradiance Equalization Algorithm

In the case of partial shadowing or photovoltaic (PV) module failure, the power provided by photovoltaic solar array significantly decreases. A promising technique to mitigate these power losses is based on the dynamic reconfiguration of the electrical connections between the PV modules. This article proposes a reconfigurable PV architecture based on Total-Cross-Tied (TCT) configuration and improved irradiance equalization (IrEq) algorithm. The PV architecture with the proposed optimization algorithm was simulated using Matlab/Simulink environment and compared to the basic equalization irradiance algorithm. The advantages of the proposed algorithm are simplicity and meaningful provision improvements in array power generation, along with the reduced processing time.
