摘要

UPFC is a common device used in many buses to growth the power of the buses. This work incorporates Trans-Z-source Inverter (TransZSI) is proposed to progress the power quality of grid connected PV and wind systems. Distinctive issues such as voltage sag harmonics and distortion cause power degradation and system failure. Voltage sag is continually one of the biggest problems for users. Closed loop PI and FOPID controlled UPFC frameworks were analyzed and their results were compared. This study is about the design and simulation of UPFC-based closed loop controlled three-phase voltage trans ZSI inverter in two bus bar system using FOPID and PI is simulated using MATLAB. Comparisons are made in terms of response time parameters such as error rate and solution time. UPFC with FOPID was found to be faster than the PI control system.
