V. TEST SYSTEM
The IEEE standard 14 bus system modeled in PSAT is the test
system is shown in Fig.3. A wind farm is incorporated into the
system in third bus since it was analyzed that the system is not
having voltage stability if it is loaded above 1.4 p.u. It is
because the system is lacking power. This additional power
required could be provided by the wind generation. This
system was analyzed for small signal stability and voltage
stability. The voltage stability analysis was done by increasing
the loads in all the buses to find the maximum loading point
and the P-V curves were plotted. The increase in load resulted
in decrease in bus voltages. With the help of P-V curves the
optimal location for the placement of STATCOM for
improving the voltage stability was found.
