Abstract: To maintain the voltage levels under acceptable limits, reactive power control is the basic requirement, thereby maintaining the stability of the interconnected power system. The ability of the power system to maintain steady acceptable voltages at all buses in the system under normal operating conditions and after being subjected to a disturbance from a given operating point is called voltage stability. Modern power systems are prone to have voltage instability problems. The placement of capacitor banks in the shunt can improve the voltage stability. The magnitude of bus voltage will increase with the use of a capacitor bank. In this work, the simple concept of using a shunt compensator to maintain the system voltage is used. Simulation of power flow without and with the capacitor bank was done using MATLAB Simulink software. Here, PMUs have been used to analyse the system parameters at each bus, thereby giving accurate results.

Keywords: Voltage Stability, Phasor Measurement Unit (PMU), Shunt Compensation, Capacitor Bank.
