Abstract

Proper placement of shunt capacitors in radial distribution system can mitigate power losses for optimal placement and sizing of shunt capacitors to minimize losses to its maximum possible and improve the voltage profile using loss sensitivity analysis and variational algorithm. Loss sensitivity factors and normalize voltages were calculated to determine the candidate locations for placement of shunt capacitors and the variational algorithm was used to determine the proper size of shunt capacitors to be placed on the system based on the selected candidate buses. The backward forward sweep algorithm of the Distribution System Application Software was used for the load flow calculations. The effectiveness of the proposed method was tested on the Feeder IV of the distribution system of Tablas Island Electric Cooperative. After the implementation of the proposed technique, two shunt capacitors are placed on the system. A 100 kV Ar shunt capacitor is placed each on phase ABCN of bus P-4-0267 and a 50 kV Ar shunt capacitor is placed on phase BN of bus P-4-0214. Thus, the system loss is reduced from 9.48% to 8.77% and the voltage profile of the system is also improved. Furthermore, the proposed method is shown to be an effective solution in finding the most suitable capacitor size and location on the feeder.
