Damping power system electromechanical oscillations using a robust adaptive TCSC controller

Abstract:

This paper is concerned with the evaluation of a robust adaptive control technique applied to damp power systems oscillations. This robust technique is based on the LQG/LTR control method, used in a self-tuning way. The stabilizer synthesized with this method is used in a TCSC device to increase the damping of low frequency electromechanical oscillations modes. The method is evaluated in a 4-machine benchmark system and simulation results show that the proposed controller presents a good performance, improving power system stability margins.
