FEASIBILITY ANALYSIS OF DGSC-UPQC

The use of Dispersed or Distributed Generation (DG) has been increased in recent years to fill the gap between supply and demand of energy, as the sources of conventional power generation are depleting fast. DGs through static compensators are also used for improving the power quality of distribution systems like mitigation of voltage dips and compensation of harmonics. Shunt, series, and series-shunt type of configuration of static compensators combined with DG have been proposed in the literature. This paper presents a feasibility analysis of DGSC-UPQC (Distributed Generation based Static Compensator as Unified Power Quality Conditioner), a series-shunt type of static compensator with DG. The analysis has been carried from technical and economical aspects when the device i.e. DGSC-UPQC is used for compensation of unbalance in source voltages and load currents and power factor improvement. Simulation results show the capability of the DGSC-UPQC to compensate the unbalance in source voltages and load currents satisfactorily.
