MODELING & ANALYSIS OF STANDALONE PHOTOVOLTAIC SYSTEM

This paper represents the three phase Photovoltaic system connected with variable load in a standalone mode’s mathematical modeling using MATLAB/ Simulink environment. The sy stem consist of a PV Array, Boost converter, three phase inverter and its control to maintain load in standalone mode. The 40 kW systems at the college site is under the study with a variable inductive load of 30kW which has to be fed by PV system in continuous mode .This paper gives analysis of each components of system while maintaining the load. The constant and boosted DC v oltage is obtained with the help of boost converter from PV Array. The three phase IGBT inverter PWM control scheme is proposed here to normalize the voltage imbalance during vari able load.
