A power system structure has the generation, transmission and the distribution systems. During the transfer of power from the generation system to the distribution system, transmission line losses are occurred. To reduce the losses and keep the system stable, many controllers are being used. The Flexible AC Transmission systems (FACTS) are the modern controllers finding application in the power systems. The Unified Power Flow Controller (UPFC) is considered to be the best among the FACTS devices. It is installed in the transmission line to maintain the voltage of the system within the prescribe limits. The location to fix the UPFC is found using Shuffled Leap Frog Algorithm (SLFA). The transformer ratio is varied from its nominal value. Testing is done using an IEEE 30 bus system and the results are discussed.

In Modern Power System power quality is the main issue of the power companies. Improvement of power quality in distribution system using photovoltaic based DPFC is declared in this paper. Flexible AC Transmission 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. In distribution system problems occur like voltage sag/swell, Harmonics etc. Photovoltaic system is used as source for DPFC.
