Comparison of the MPPT command based on the PSO, P&O, and IncCond algorithm implemented in Dspace

Abstract

Several algorithms have been offered to track the maximum power point when we have one maximum power point. In this paper, we will propose an improved maximum power point tracking method for the photovoltaic system that utilizes a modified PSO algorithm. The main advantage of the method is the decreasing of the steadystate oscillation (to practically zero) once the maximum power point is located. moreover, the proposed method has the ability to track the maximum power point under extreme environmental conditions. To evaluate the effectiveness of the proposed method, MATLAB simulations are carried out under very challenging circumstances, namely step changes in irradiance and step changes in load. Finally, its performance is compared with the «perturbation and observation” and incremental conductance. The results obtained were validated by a PIL (Processor In the Loop) co-simulation using the DSpace 1104 card.
