Installation of UPQC in Radial Distribution System for Enhancement of Voltage Profile

Most of the loadLoad in electrical distribution systemsElectrical distribution system is of inductive type, which leads to various issues like reduction in load end voltage profileVoltage profile, increase in line losses, etc. Reactive power compensationReactive power compensation can be used to overcome these problems. There are various reactive power compensationReactive power compensation devices and several techniques too are available in literature. Few of the devices include capacitorCapacitor banks, on-load tap changing transformersOn-load tap changing transformers and distributed generators. The latest trend is the usage of distribution flexible alternating currentAlternating current transmission system (FACTS) devices. Distribution flexible alternating currentAlternating current transmission system (DFACTS) devices are also used to improve the power qualityPower Quality. Unified power quality conditioner (UPQC) is a one of the prominent DFACTS device. UPQC basically aims on mitigating the power qualityPower quality problems. The work proposed in this chapter focuses on suitable location and sizing of UPQC for reactive power compensationReactive power compensation in a radial distribution systemRadial distribution system to ultimately improve the voltage profileVoltage profile. The approach is applied to 15, 33 and 69-bus radial distribution systemsDistribution system and the results have been analyszed.
