Abstract |
As power electronics increasingly replaceSynchronous Generators (SGs), the focus on system frequencystability has grown. To study frequency dynamicsduring disturbances, time-domain models, such as thesimple single-node model, are used. The commonly usedsingle-node models lack sufficient representation of electricpower dynamics, simplifying converter-interfaced generation(CIG) behavior as reduced system inertia. However,control strategies, such as Power System Stabilizers(PSS) on SGs or Power Oscillation Dampers (POD) onCIG, can modify the system-wide frequency response.This paper presents a comprehensive state-space modelof a SG for single-node studies, offering flexibility toanalyze electrical interactions involving the AutomaticVoltage Regulator (AVR) and PSS, while facilitating theinclusion of power electronics. Additionally, the modelprovides a mathematical framework for understanding therelationships between system parameters through statespacerepresentation and could be used to explore othercritical interactions. |
