Multiobjective Damping Controller Design of Power System Oscillations by HVDC Link Using Genetic Algorithm

Abstract HVDC devices have been widely applied in power system for their excellent and flexible control abilities. The fast response characteristics of HVDC system can be used efficiently to damp power system oscillations without additional equipments. In this paper a methodology is developed to design multiobjective damping controller using the Genetic Algorithm to improve the dynamic stability of power systems with HVDC Link. The stabilizers are tuned to simultaneously shift the lightly damped and undamped electromechanical modes of all plants to a prescribed zone in the s-plane. Eigenvalue analysis and nonlinear simulation results show the effectiveness of the proposed method to damp out the local and interarea modes of oscillations and work effectively over a wide range of loading conditions and system configurations.
