Beschreibung:
Voltage stability is a critical issue in the secure operation of the restructured power system. Poor voltage conditions lead not only to voltage collapse in the system but can also induce oscillatory instability that may cause a loss of synchronism. A critical question is how to estimate the distance to voltage instability given the present state of the system.
This book offers a practical survey of continuation- and bifurcation-based approaches for assessing the stability of power system voltage. Beginning with definitions based on IEEE/CIGRE voltage stability classifications, the text demonstrates the need for robust numerical techniques for addressing aspects of voltage instability. The basic concepts of bifurcation theory and continuation methods are presented in tutorial form, along with information on continuation power flow. The text includes access to web based simulation tools which users can use to simulate test systems.
