Performance of MPPT Under Irradiation Changes on PV Systems

Abstract: As an intention to meet the growing energy demand and to change from all costly fossil fuel sources, many countries have promoted renewable energy source. PV costs are dropping and a lot of attractive projects have resulted throughout the world. Furthermore, the easy and quick implementation of Solar PV gives it a competitive advantage over other renewable energy sources. A MPPT technique is implemented to the system to track the maximum power point of PV. This paper presents a comparative study of seven conventional Maximum Power Point Tracking (MPPT) algorithms. Their performance is evaluated using the simulation tool called Simulink. In particular, this study compares the behaviors of each technique in the presence of solar irradiance. The Results show that Hill Climb, Perturb and Observe and Incremental Conductance generate much more energy under constant condition. And also that the MPPT Constant Current does not vary under the change of irradiation and has a fast response to reach a steady state compared to the other ones.
