Nonlinear Robust Adaptive Control Design for Dc Power Modulation in Multi Area AC/DC Power Systems

Abstract

decent response to ensure stability. In order to solve these Abstract-A nonlinear robust adaptive controller for dc power problems, there has been a great deal of research in the modulation of interconnected ac/dc power systems is proposed application of nonlinear control theories in power system and is used to damp tie line power oscillations in interconnected control, and the most established ones include applications of power systems. The design idea is to drive the centers of inertia robust control theory and differential geometric theories. In the (COI) of various interconnected areas to a stable equilibrium application of differential geometric theory, nonlinear systems point such that the oscillations in the system can be damped out.. . 'Genetic algorithm is applied to optimize the parameters of the ar transf ormedinlearpones such that various existing proposed controller, and computer test results illustrate that the linear control theories can be applied [3]- [5]. The drawbacks of proposed controller is superior to the conventional linear dc such an approach are that exact knowledge of the mathematical power modulation controller.. model of the studied system is required, and uncertainties such Index Terms-Center of Inertia, Genetic Algorithm, HVDC as model errors and disturbances are neglected. Robust control transmission, Nonlinear robust adaptive control, Power system. theories have been proposed to solve such problems and to enhance the robustness of control methods in power systems
