The Effect of Load Models on Unstable Low-Frequency Oscillation Damping in a Longitudinal Power System

摘要

This paper uses the eigenvalue analysis approach to observe the influence of lad models on the electromechanical oscillation mode phenomena during an unstable low-frequency oscillation incident which recently occurred on the Tai- wan power system. Three kinds of the derived load models (dynamic model, composite model, and exponential model), based on the component approach with measured characteristics of power system loads, and used.
