  • This paper presented application of a new variant ofGenetic Algorithm, specialized in multi-objective optimizationsproblem known as Non-dominated Sorting Genetic Algorithm II(NSGA-II), to obtain the optimal allocation of Unified PowerFlow Controller (UPFC) for enhancing the power systemloadability as well as minimizing the active power loss intransmission line. An Optimal Power Flow (OPF) problem withmixed integer programming has been formulated for optimizingthe above two objectives as well as obtaining the optimal locationof the UPFC while maintaining the system security and stabilitymargins, e.g., small signal stability, voltage stability index, andline stability factor. In addition, a fuzzy based mechanism hasbeen employed to extract the best compromise solution from thePareto front. The effectiveness of the proposed methodology hasbeen investigated on a standard IEEE 30-bus and practical JavaBali24-bus of Indonesian systems. Results demonstrate that thestatic and dynamic performances of the power system can beeffectively enhanced by the optimal allocation of the UPFC.Moreover, UPFC installation cost is also calculated and overallperformance has been compared with existing method.
