Abstract

Under Partial shading conditions (PSC), traditional MPPT methods such as, P&O, IncCon and SMC, cannot track down the Global MPP. Thus, the energy conversion of the PV modules will decrease. To overcome this drawback, two evolutionary algorithms; PSO and CS, were presented. Also, the study introduces a hybrid optimization method to enhance the overall performance of the PV system under PSC. MATLAB simulations will be used in order to illustrate the efficiency of the proposed method.
