Abstract

A nonlinear robust adaptive controller for dc power modulation of interconnected ac/dc power systems is proposed and is used to damp tie line power oscillations in interconnected power systems. The design idea is to drive the centers of inertia (COI) of various interconnected areas to a stable equilibrium point such that the oscillations in the system can be damped out. Genetic algorithm is applied to optimize the parameters of the proposed controller, and computer test results illustrate that the proposed controller is superior to the conventional linear dc power modulation controller.
