In the present work , a new solution for suboptimal control of power system dynamics based on the nonlinear gradient approach has been developed. The choice for control feed back variable is based on a primary sensitivity analysis which only selects the most effective feedback variables to bring the system dominant modes to predefined locations. The method has the advantages of being more efficient computationally and it would allow for a closer solution to optimal solution than other methods of suboptimal control. The method applied to a three machine
system and the results are compared with optimal control and another suboptimal control results which shows the advantage of new method.
