Modeling and Simulation of Photovoltaic Pumping System Used for Irrigation

this paper presents the modeling and simulation of photovoltaic pumping system which consists of PV panel, DC-DC converter, and DC motor driving a centrifugal pump. These systems are very useful for remote areas with no access to power grid. The output power of PV panel strongly depends on external conditions such as solar irradiance and temperature. The fuzzy logic maximum power point tracking algorithms have been implemented to regulate the duty cycle of the DC-DC converter. A comparison between Photovoltaic pumping system with MPPT connection of the PV panel and Photovoltaic pumping system with direct connection of the PV panel are performed to show the efficient of MPPT controller.
