heal.abstract	Dynamic stability problems are usually overcome through the application of power system stabilizers. The authors present an alternative approach for power system stabilization that based on the tuning of existing generator controllers, both governors and voltage regulators. The sensitivities of the eigenvalues to the controller parameters are evaluated and an optimization technique is developed to maximize the dynamic stability. Application of the parameter optimization method on a realistic model of the Hellenic interconnected system has proved to be an efficient way to stabilize a number of unstable oscillatory modes by relatively small parameter variations. The results are tested with a nonlinear simulation program and the achieved stabilization, as shown by the rotor angle swings, is found to be significant.	en
