Abstract: Due to massive increase in the power transactions due to restructuring, the stress in transmission lines has increased largely and severity assessment is very essential. Contingency assessment of a power system predicts the effect of outages in transmission lines and generator units. In this paper, contingency ranking of the lines has been done using composite severity index. A risk-based strategy has been adopted for the placement of interline power flow converter (IPFC). From the list of the severe lines obtained, IPFC is placed on the line which has highest possibility of severity during the occurrence for different outages. To verify the proposed methodology, it is implemented on IEEE 30 and Indian Utility 62 bus systems. The load on the bus with highest load is further increased gradually up to the critical value and the results have been presented and analysed to ascertain the effectiveness of IPFC for contingency management.
