| 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 optimization objective function constructed by damping ratios of poor damping electromechanical 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 on the New England test power systems validates effectiveness of the method and the robustness of the resulted PSS parameters against the variations of system operating mode. |
