Modeling and Simulation of Solar PV System for Water Pumping

Abstract

Solar Photovoltaic (PV) systems are having growing importance in present time of our power system due to its non-polluting, minimum maintenance, and free fuel characteristics. Photovoltaic systems are comprised of photovoltaic cells, devices that convert light energy directly into electricity. Since the source of light is usually the sun, they are often called solar cells. Photovoltaic modules are widely used in induction motor applications. One of these applications may be in water pumping system. The boost converter has been used boosting the weak output voltage generated by the cells. Boosting of voltage is being done in reality by the maximum power point technique (MPPT). In this technique the automated tracking to give the highest output power is done by an algorithm. This generated power is fed to a boosting load across which the boosted output voltage is being received. This output voltage is then fed to operate a induction motor, driving a pumping system.
