EN The losses in the power transmission network may increase due to contingency conditions, i.e., contingency analysis is flattering a crucial task for power system scheduling and operation. It is required to forecast the outcome of outages in power system. Contingency may be occurred due to failure of equipment or transmission lines. Single line outage also overloads the other lines, and abrupt voltage drop may cause the outage of other lines. Hence, the contingency analysis plays vital role to handle different system operating conditions. In this paper, n-1 contingency condition is considered to find the impact of shunt capacitor for improvement in voltage profile, where Mi Power package has been used for the conduction of simulation on the considered test network. Voltage Collapse Prediction Index is the method used for finding the optimal placement of shunt capacitor under n-1 contingency. The highest VCPI value indicates the weak bus, therefore, that is the best place for placement of shunt capacitor to improve the voltage profile and reduce the losses. The value of bus voltages, real power losses and real power generation before and after the n-1 transmission line contingency have been examined, where the improvement of voltage profile through optimal location of shunt capacitor has been studied. The usefulness of the shunt capacitor has been verified on 5 bus test system under n-1 contingency condition using MiPower software.
