A Redundancy Based Optimal Placement of Interline Power Flow Controller Using Composite Severity Index for Contingency Management

Abstract

Contingency assessment is an essential task for the stable and reliable operation of a power system as it predicts the effect of outages in transmission lines and generator units. In this paper, a recurrence of severity based placement strategy for Interline Power Flow Controller (IPFC) has been proposed. Contingency ranking of the lines has been done using Composite Severity Index. A probabilistic based strategy has been adopted for the placement of IPFC. IPFC is placed on the line which has the highest probability of severity during the occurrence for different outages. To verify the proposed methodology, it has been tested on IEEE 14 and 30 bus system. The load on the bus with highest load is further increased gradually up to the critical value and the results have been presented and analyzed to ascertain the effectiveness of IPFC for contingency management.

“…Similar study had been conducted by the same author in [199]. The proposed approach in [197][198] may be very cumbersome for large and complex network. Hence, the author had introduced rapid contingency ranking technique for selecting few important buses to ease the procedure of identifying the most severe lines through CSI.…”

“…Mishra in [197][198] introduced a combination of two separate indices, LUF and FVSI to indicate the overloading line and bus voltage violations. The combination of these two indices is known as composite severity index (CSI).…”

“…The most severe lines in which corresponding to every line outage had been determined and lines which are connected between load buses had been highlighted as the priority list for IPFC placement. The proposed analytical approach had been implemented on IEEE 14 bus and IEEE 30 bus test systems in [197]. In [198], the proposed work had been adopted on IEEE 30 and Indian Utility 62 bus systems.…”
