Comparative of performance for UPFC with DPFC

Abstract

UPFC and DPFC are two important devices for power quality improvement. These FACTs devices are generally used between sending end and receiving end. This paper deals with comparison of UPFC & DPFC systems operating at same load and same sending voltage. A basic two bus system with UPFC is modelled and simulated. Basic DPFC system with multiple DVRs is also modelled and simulated. The results are compared in terms of real power, reactive power and THD. The result of comparison indicates that two bus system with DPFC gives better performance when compared to two bus system with UPFC.
