2.6. Methods of Analysis for Determining Voltage Stability in Microgrids
The vulnerable sections of the network may be identified through appropriate volt-
age stability assessment methods. Selecting a suitable method for voltage stability analysis
of a network depends on mainly two aspects of the problem: (a) proximity to voltage in-
stability, and, (b) mechanism of voltage stability [52]. Appropriate mitigation methods can
then be applied to enhance the stability of the network. Voltage stability in general can be
evaluated by two different methods of analysis, static and dynamic, as presented in Figure
5.
System dynamics that influence voltage stability are usually slow. Therefore, voltage
stability analysis can be done by using some selected static operating conditions of the
power system. The static analysis techniques can highlight the nature of the problem re-
lated to voltage stability and identify the key contributing factors. Dynamic analysis, on
the other hand, is useful for detailed study of specific voltage collapse situations, coordi-
nation of protection and controls, and testing of remedial measures.
