ABSTRACT
In this document, the Cuckoo Search (CS) algorithm based optimal location of UPFC to improve the voltage stability of the power system is proposed. The novelty of the proposed method is exemplified in the improved searching ability, random reduction and reduced complexity. In this regard, the generator outage affects the system voltage stability constraints such as voltage, power loss, real and reactive power. Here, the CS technique optimizes the maximum power loss line as the suitable location of the UPFC. The affected voltage stability constraints are restored into secure limits by connecting UPFC at optimum location given CS algorithm. The proposed method is implemented in the MATLAB/Simulink platform and tested under IEEE 14 standard bench mark system. The proposed method performance is evaluated by comparison with those of different techniques such as ABC,GSA & Bat algorithms. The comparison results invariably prove the effectiveness of the proposed method and confirm its potential to solve the related problems.
