Abstract
This thesis focuses on increasing energy extraction in stand-alone PV water pumping systems by improving maximum power point tracking (MPPT). A photovoltaic dependent maximum power point tracking technique is introduced, modeled and assessed. It is then compared with the conventional Perturb and observe and incremental conductance techniques. The results show that the curve fitting MPPT has faster dynamic response and eliminates oscillations around the MPP under steady-state conditions.The three MPPT methods are implemented in the simulated PV water pumping system and compared.The results confirm that the new method has improved energy extraction and dynamic tracking compared with simpler methods. All simulations were done using MATLAB/SIMULINK
