Improvement of power quality in grid system based on zeta converter integrated with PV supply

Renewable power grid integration is an option for the supply of constant electricity. The semiconductor technology-based advancement is improving loads of the power electronics penetration. This paper presents a new definition of optimum use of a unified conditioner for power efficiency. The show UPQC inverter is tested for simultaneous sag and swell compensation using three-leg inverters associated with the power transmission lines. The ZETA converter is proposed to enhance the dc-link capacitor voltage generated from the PV module's renewable energy system. The converter is maintaining constant power through the MPPT based PI controller. The control of the shunt and series compensators is accomplished. The results are improved compared to the conventional control systems. The PV energy is fed to the converter, which powering the inverter. The power inverter injects power in the power system lines in the form of shunt and series compensators. The results are obtained using the Simulink environment.
