		abstract={The Aceh power subsystem is highly vulnerable to voltage instability problems. This 
is due to radial network topology and lack of large generators that can compensate for 
changes in reacive power. Analysis such as simulation of power flow and voltage stability 
is needed to determine how significant for voltage problems can be to cause more 
considerable disturbances such as Voltage Collapse. The static voltage stability analysis 
method using Voltage Busbar Sensitivity approach is carried out with Digsilent software 
to calculate the busbar voltage sensitivity ratio (dV/dQ) for each scenario of the operating 
conditions the Aceh power subsystem, from normal to worst conditions and mitigation 
planning. Based on the simulation results, in the absence operations of Naganraya steam 
powerplant units, the shunt capacitor operating is only able to improve the operational 
voltage for each substation in the Aceh power subsystem at the range of 145 -153 kV, but 
it does not significantly reduce the value of the busbar voltage sensitivity ratio. The 
combined operating conditions of the 150 kV Aceh subsystem backbone looping and the 
North Sumatra ? Aceh 275 kV interconnection can reduce the value of busbar voltage 
sensitivity ratio (dV/dQ) at each substation in the Aceh power subsystem, even the highest 
is only around 0.001 p.u/MVAR. Then busbar voltage sensitivity ratio data is expected to 
help power system operators to avoid the potential for Voltage Collapse in operating the 
power system.}
