It is an important task to accurately estimate the Thevenin equivalent impedance seen from a load bus for power systems monitoring and control. The purpose of this paper is to investigate the mechanism and characteristics of the Thevenin equivalent impedance in a nonlinear circuit. A general model is introduced for investigating the Thevenin equivalent impedance in an analytical manner. Two typical...
This paper reveals that the impedance match (or the Thevenin circuit) based voltage stability monitoring techniques have problems to predict voltage stability limits when applied to multi-load power systems. Power system loads are nonlinear and dynamic. They cannot be simply represented as Thevenin circuit parameters for impedance match analysis. To overcome these difficulties, a new concept called...
