  Ever-growing electrical loads are having a huge impact on the operation and
stability of the power system. Moreover, the integration of renewable
generation poses various challenges to the future power system, especially,
regarding stability. Thus, this paper presents the impact of synchronous
condensers (SCs) on static voltage stability analysis for a test transmission
network, considering line contingencies, in the presence of renewable
generation. The main purpose of this study was to identify critical buses in
the power system when line contingencies occur. Both (N-1) and (N-2)
contingencies were considered in this study. The impact of renewable generation
is also assessed. To analyze the static voltage stability, the conventional
power-voltage (P-V) curve method, using continuation power flow (CPF), is
applied on the IEEE 14-bus test system. DIgSILENT PowerFactory software
simulations are used to obtain the results. The P-V analysis accurately
quantifies the critical buses for both cases, considering (N-1) and (N-2) line
contingencies.
