Abstract
Steady-state voltage instability can certainly be enhanced by static VAR compensators which can hold certain node voltages constant and create infinite buses within the system nodes. Static VAR compensator parameters needed for this purpose are found. Controller gains, droop slopes, reference voltages and compensator ratings are determined for maintaining the load node voltages constant irrespective of system loadabilities to values which lead to voltage instabilities. Influence of system equivalent impedances on these parameters is finally discussed.
