Abstract

In this paper a nonlinear PID controller is suggested for damping the interarea power oscillation of interconnected power systems. A differential tracker is introduced to obtain a low-noise derivative of the controller input signal. The nonlinear PID controller is applied on STATCOM supplementary control. A computer program for transient and steady-state stability study has been developed based on the Power System Toolbox of MATLAB. Computer tests show clearly the effectiveness of the nonlinear PID controller and the good performance of the differential tracker
