Abstract
This thesis proposes two methods to estimate transfer function models using System Identification technique that can be used to estimate Control Performance Standard 1 (CPS1) index. The first method is applicable when a load-frequency time domain simulation system of an interconnected power system for estimation of CPS1 is available. This method models an accurate approximate equivalent power system external to a system under consideration. The second method is applicable when a time domain simulation model for estimation of CPS1 is not available. This method uses System Identification technique to model two transfer functions to produce necessary data for the estimation of CPS1. The necessary up-to-date data for System Identification can be obtained from a practical power system dynamic simulation model. The developed models are used to estimate CPS1. The research described in this thesis also shows the applicability of a previously developed method of estimating CPS1 in a practical power system. The techniques, methodology and results presented in this research should provide useful information for operating and planning of power systems.
