Abstract

The proposed system ensures the injection of the generated power from the PV array in to the distribution grid with less total harmonic distortion (THD). Photovoltaic (PV) array, Pulse width modulation based (PWM) DC-DC converter, multi-level voltage source inverter, complete system with the control was modelled and simulated in MATLAB Simulink environment. The proposed control strategy has produced a more accurate output current and voltage with Total harmonic distortion (THD) of 1.06 and 1.99%, respectively as compared to a research work conducted in 2014 by Ahuja, R.K. and Kumar, A. S. with current THD of 1.43%.
