Implementation of Power System Model Identification for Locating In-phase Generators

Abstract

The paper describes investigation of the new opportunities for power system monitoring using Wide Area Measurement Systems (WAMS). Phasor Measurement Unit (PMU) data is used for power system model identification in the form of state-space model. Implementing the modal analysis to identified state-space model gives the opportunity to control proximity of the operation point to the feasibility boundary and track in-phase generators. All time domain simulations of the research are conducted for two-generator-swing-bus system. Calculations were carried out in Matlab. © 2012 IEEE.
