In Modern Power System power quality is the main issue of the power companies. Power quality improvement in distribution system using photovoltaic based DPFC is stated in these paper. Flexible AC Trasmission System(FACTS) device which is known as distributed power flow controller (DPFC)is used. DPFC is derived from UPFC by eliminating common dc link between series and shunt converter. Unified power flow controller( UPFC) is widely used and control all parameters of the system .The UPFC handle the current and voltage with high rating; therefore the cost of system is high. Therefore distributed power flow controller (DPFC) is used due to high control capability, high Reliability & low cost .DPFC also measures the transmission angle, line impedance and bus voltage . problem occurs on distribution system like Voltage sag/swell,harmonics etc.In these paper we are using photovoltaic system for DPFC.
