| Abstract: | The role of Power System Stabilizer (PSS) in the power system is to provide necessary damping torque to the system in
order to suppress the oscillations caused by a variety of disturbances that occur frequently and maintain the stability of
the system. In this paper, a PSS design technique is proposed using Whale Optimization Algorithm (WOA) by
considering eigenvalue objective function. Two bench mark multi machine test systems: three- generator nine- bus
system, two- area four- generator inter connected system working on various operating conditions are considered as
case studies and tested with the proposed technique. Extensive simulation results are obtained and effectiveness of
proposed WOA-PSS are compared with well - known PSO and DE based stabilizers under several disturbances. |
