STATIC LOAD MODELLING AND VOLTAGE STABILITY INDICES

open access: yesInternational Journal of Power and Energy Systems, 2009
This paper analyzes the performance of some of the widely used voltage stability indices, namely, singular value, eigenvalue, and loading margin with different static load models. Well-known ZIP model is used to represent loads having components with different power to voltage sensitivities.

Voltage Stability Analysis Using Static and Dynamic Approaches

IEEE Transactions on Power Systems, 1993
The authors discuss voltage stability analysis of power systems using static and dynamic techniques. Using a small test system, results of time domain simulations are presented to clarify the phenomenon of voltage instability and to better understand modeling requirements. The same system is then analyzed using a static approach in which modal analysis

Dynamic and Static Voltage Stability Enhancement of Power Systems

IEEE Transactions on Power Systems, 1993
The static voltage stability and the dynamic voltage stability are integrated. To consider a shunt compensator and/or a more general load which is dependent on voltage, a modified criterion for the static voltage stability is developed and the system is controlled to satisfy this static stability criterion.

Method of Combined Static and Dynamic Analysis of Voltage Collapse in Voltage Stability Assessment

2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005
Different analysis methods have been used for voltage stability assessment. In comparison with static analysis methods, little work has been done on dynamic analysis of large interconnected power systems. Voltage instability can be studied effectively with a combination of static approaches and time simulations.

Regenerating-Mode Stabilization of the “Statically Compensated Voltage Model”

IEEE Transactions on Industrial Electronics, 2007
Reversal of rotation under load of sensorless induction motor drives is very challenging, as there is often an unstable region in the low-speed regenerating mode. In this paper, a variant of the classical "voltage model", i.e. the "statically compensated voltage model", is modified for stable regenerating-mode operation with accurate model motor ...

Static Analysis of Voltage Stability

2021
The static analysis method of voltage stability is to capture the system state on different time sections along the time track. By assuming that the differential of the system state variables on the section is zero, the differential-difference-algebraic equations describing the nonlinear dynamic power system are simplified to pure algebraic equations ...

Static and dynamic approaches for analyzing voltage stability

European Transactions on Electrical Power, 2006
AbstractVoltage stability analysis always involves a large number of devices with various dynamic characteristics in power system. For properly capturing static and dynamic behaviors providing insights into characteristics of the voltage stability of the system, different system models are established for different time‐scale studies.

Effects of FACTS devices on static voltage stability

2000 TENCON Proceedings. Intelligent Systems and Technologies for the New Millennium (Cat. No.00CH37119), 2002
This paper presents a study of FACTS devices mainly static VAr compensator (SVC) and controlled series compensator (CSC). Their steady-state modeling and effects on power system performance have been studied. It also studies static stability improvement of a power system and hence power flow improvement in the network.
