Abstract
This paper presents the cascade multilevel UPQC for sag and swell mitigation of a grid connected hybrid system. Power quality is the major problem facing by today’s power system. Due to the use of power electronic converters and devices the harmonics are injected into the grid that may result in grid failure. To mitigate these harmonics custom power devices are used. UPQC is the custom power devise that is used in this paper. The seven level cascade multilevel converter is used for both the series and shunt inverters of UPQC for better harmonic distortion. This system is connected to the PV+WIND hybrid system to provide effective utilization of the resources. The UPQC contains a DC link which controls the Sag and Swell, LG Fault and improves the power quality of the system. This system is simulated in MATLAB/SIMULINK
