Simulation of reconfiguration system using matlab-simulink environment

Abstract

Reconfiguration strategy of solar energy has been a challenging task in the energy opti- mization field, in which the intention is to minimize losses and increase efficiency of the photovoltaic (PV) system under non-homogeneous solar irradiation based on irradiance equalization. The recon-figuration system (RS) proposed includes: irradiance equalization algorithms which is effective in the calculation to find an optimal configuration; dynamic electrical scheme (DES) switching matrix which is controlled to obtain the optimal configuration for PV array. Recently, publications have focused on bringing out the algorithms with the aim to select the optimal connection configuration and control DES switching matrix. However, to our knowledge, there has been no published work using Matlab-simulink to simulate the RS operation. The simulation enables researchers to perform experiments and evaluate reconfiguration algorithms effectively before deploying in reality. In the paper, we present a study on simulation of RS operation using Matlab-simulink environment. The results show that, with RS, the effectiveness of the PV array performance can rise by 10-50%.
