Description
Summary:The problem of tuning of stabilizers in multimachine power systems has been formulated both as a quadratic and a linear programming problem. The objective is to shift the lightly damped poles associated to the system mechanical modes. The structure of the transfer function of the stabilizers has been chosen a priori, being the optimization performed with respect to its free coefficients. A usual phase lead characteristic has been included in the constraints. Numerical results are presented for a three-machine power system.
