Application of AHP method for optimal location of SSSC device under different operating conditions

Abstract

FACTS devices can enable a line to carry its flow close to rating capacity and consequently can improve the power system security even in contingency and over loaded network. An opposition-based modified differential evolution algorithm is proposed to solve the OPF problem under different operating conditions for enhancement of power system performance with a SSSC device. The best location of SSSC device is determined based on AHP method. The effectiveness of the proposed method is demonstrated on IEEE 30-bus test system.
