The paper deals with the simulation study of PV cells as well as power quality conditioner for voltage sags. A computer simulation derived study of photovoltaic cells or modules utilizing MATLAB is demonstrated. The MATLAB is an analog simulator or digital simulator which estimates voltage and current in a circuit under a variety of distinctive situations. This MATLAB is used to simulate a circuit based model for PV cells or modules and then to conduct a behavioral analysis under altering conditions of solar insolation, including blending effect, temperature, diode model variables, series and shunt resistance. In future the supporting services provided by PV system could speed up their penetration in to power systems. Furthermore low power PV systems can be used effectively to enhance the power quality using MPPT algorithm. This paper presents a single -phase voltaic system that furnishes grid voltage support and compensation of harmonic distortion at the point of common coupling (PCC). Simulation results validate the proposed solution.
