An Improved Shuffled Frog Leaping Algorithm for Simultaneous Design of Power System Stabilizer andSupplementary Controller for SVC

This paper presents a new Modified Shuffled Frog Leaping Algorithm (MSFLA)applied to design simultaneous coordinated tuning of damping controllers to dampthe power system low frequency oscillations. For this, a new frog leaping rule isproposed to improve the local exploration and performance of the original SFLAand the genetic mutation operator is employed for new frog generation instead ofrandom frog generation to improve the performance and quicker algorithmconvergence. In order to verify the effectiveness of the proposed method, a 2-area-4-machine and a 5-area-16-machine power system are considered which two powersystem stabilizers (PSSs) are designed coordinately for the first system and one PSSfor a generator and one supplementary controller for a Static Var Compensator(SVC) are designed simultaneously for the second system. To show the effectivenessof the designed controllers, study systems are tested under two different operatingconditions and simulation studies are presented.
