Stabilization and control of the power system using meta-heuristic algorithms

The Cuckoo Search algorithm (CS) is introduced in this paper for installing optimal Power System Stabilizers (PSSs) designed in a multimachine power system The problem of setting the PSSs parameter is formulated as an optimization problem solved by CS algorithm A special value based on the objective function including the damping ratio and the damping factor of the lightly damped electromechanical modes is considered for the PSSs design problem The performance of the proposed CS based PSSs (CSPSS) has been compared with Genetic Algorithm (GA) based PSSs (GAPSS) and the Conventional PSSs (CPSS) under different operating conditions and disturbances The results of CSPSS have been developed through timedomain analysis special values and performance indicators Also the effect of the proposed algorithm in providing good damping characteristics has been confirmed
