Nowadays, the increase in the usage of non-linear loads especially the power electronic equipments leads to deterioration of the quality of voltage waveforms at the point of common coupling (PCC) of various consumers to improve the waveform various power flow controlling devices are available. Power flow is controlled by adjusting the parameters of a system, such as voltage magnitude, line impedance and transmission angle. One of the DPFC is UPFC. DPFC is obtained from UPFC. This is to use multiple small-size single-phase converters instead of the one large-size three-phase series converter in the UPFC. The large number of series converters provides redundancy, thereby increasing the system reliability. As the D-FACTS converters are single-phase and floating with respect to the ground, there is no high-voltage isolation required between the phases.
