Improvement of voltage profile by using line reconfiguration and distribution transformer placement

Due to increase in population and change in the life style there is huge burden on the power system mainly on the transmission and distribution infrastructure. Inspite of increase in the generation existing infrastructure is not able to meet the demand because of ageing and transfer capability. The overloading of this transmission lines creates more power loss and reduction of these losses can be achieved by line reconfiguration, express feeder lines and distributed transformer placement. In this paper IEEE 33 bus system is considered for the analysis. The line reconfiguration and distributed transformer placement analysis is done in MiPower-9.0 version and satisfactory results are obtained in terms of power loss reduction and voltage improvement.
