Reactive power compensation using shunt capacitor and transformer tap changing for loss minimization and voltage stability in power system

This project describes the effect of reactive power compensation by using shunt capacitor and tap changing transformer in minimizing losses and maintaining the voltage stability of the power system. The size and location of capacitor bank is determined by using stability index (L) method. Then shunt capacitor is installed at weakest bus and reactive load is increased. The shunt capacitor and the transformer tap changing are combined to minimize losses. The proposed method was applied to a 30 bus bar IEEE systems to show its feasibility and capability. All simulation was done using the MATLAB version 7.0 programming.
