Despite time varying system demand and stochastic nature of
wind power, maintaining a suitable voltage profile and hence
voltage stability is very important to operate the system with
sufficient reliability and security margin. Voltage stability (VS)
of a system can be classified into static and dynamic [7].
Static voltage stability analysis mainly focuses on determining
the maximum loading capability of the network. On the other
hand, dynamic voltage stability analysis focuses on
determining the mechanism of voltage collapse. The wellknown
P-V curve is normally used as a tool in assessing static VS of a system.
Plotting of P-V curve requires the results of multiple load flow solutions [7, 8].
Other methods of determining static voltage stability are also described in a
number of articles but are mainly applicable for high voltage
transmission systems [9-11]. However, only a few articles
described the evaluation of VS of a distribution system when
integrated with wind generators [12-13].
