ABSTRACT

Due to increasing demand of electric power supply and shortage of natural resources. it is necessary to use the renewable energy resources. World has solar Photovoltaic energy potential due to ease of availability and huge amount of potential. to meet its over increasing energy demand. Th is research purposes the performance and operation of Photovoltaic system to provide i n detail analysis of the semiconductor physics and the Photovoltaic phenomena. The modeling and simulation of grid connected PV system which is the main objective of this research. Then main emphasis is to be placed on the photovoltaic system. t he modeling and simulation photovoltaic system, the MPPT control and the DC/DC converter and DC/AC
inverter have been analyzed and evaluated. The step of modeling with MATLAB and SIMULINK of the photovoltaic system is shown respectively and simulation results are provided .The results of SIMULINK model of the PV system could be used in the future for extended study with different DC/DC converter topology. Optimization of MPPT algorithm can be implemented with the existing Photovoltaic and DC/DC converter and DC/AC inverter
