Application of shuffled bat algorithm for optimal sizing and location of thyristor controlled series compensator

This paper presents an algorithm for optimal placement and size of the series FACTS device considering branch loading, voltage profile improvement and loss minimization as multi objectives. FACTS device studies and for every combination indices branch loading, voltage profiles are studied. To optimize the objective function new optimization technique called shuffled bat algorithm is proposed. The work is tested on IEEE-30 bus system with different % of loading such as 90,100 and 110% of base load condition. With shuffled bat algorithm, the voltage profile of the system and branch loading with different loading conditions are presented. The performance of the proposed algorithm is compared with conventional sensitivity based optimization method and presented for illustration purpose.
