Abstract

Methodology of robust controller design for transient stabilization of the interconnected power systems is presented. The model of the interconnected power systems for braking resistor control is derived, and a PID controller is proposed to control the amount of power dissipated by the brake. The Kharitonov approach is used for an initial tuning of the controller gains. Next, transient energy functions are applied for final controller tuning and choice of the actuator size, operating and restraint characteristics. The multiple equilibria problem is addressed and a solution is proposed. Technical implementation issues of the control scheme are discussed. The controller design and tuning procedure for a multimachine model is illustrated by a simulation example
