Abstract
In order to enhance electricity quality, a grid-connected photovoltaic (PV)
system simulation is presented in this study. A 200 kW photovoltaic system
is integrated to a utility grid and loads. A 25 kV 3-level insulated gate
bipolar transistor (IGBT) bridge converter is used. Through this system
integration of a renewable energy source with a non-renewable source is
achieved. This system also wins over the intermittent nature of the
renewable source (solar energy) and non-reliability of conventional sources
(utility grid). Power and signal quality for various signals such as ripple
factor and total harmonic distortion has improved. The suggested system is
investigated using MATLAB/Simulink environment. Total harmonic
distortion (THD) in voltage and current, ripple factor correction is also
incorporate in the MATLAB model.
