【Abstract】 A new simulated annealing(SA) method that incorporates a simplex method into the procedure of simulated annealing algorithm is proposed to deal with the parameter optimization in design of power system stabilizers(PSS).With an optimizations objective function constructed by poor damping eigenvalues,the new SA method inherits the advantages of the simulated annealing algorithm and the simplex method so as to have both strong global researching capability from the former and quick local convergence from the latter.An eigenvalue study on the IEEE 4-generator test power systems validates effectiveness of the method and the robustness of the resulted controller parameters against the variations of system operating mode.更多还原
