This paper deals with the midvoltage control problem of a power system consisting of a single generator ma chine connected to an infinite bus using an advanced static var compensator (ASVC). We propose a PI-like controller design which enables to regulate the mid voltage to a desired reference voltage. The proposed control design is based on the derivation of a suitable model of the mid-voltage dynamics. We show that the structure of the dynamics of the root mean square value of mid-voltage can be chosen as a linear first order system with unknown time constant. Simula tion results are provided to validate the model of the mid-voltage and to show the performance and the ro bustness of the proposed controller.
