Abstract: The goal is to offer a new technique for ascertaining the optimal location along with the quantity of reactive power (RP) to be injected to ameliorate the voltage stability (VS) of Radial 28 bus system that is susceptible to voltage instability. A new sensitivity matrix termed L-Index sensitivity matrix is proposed and the same is pondered for recognizing the buses, at which the RP is to be injected. The proposed work is tested for a practical instance of a Radial 28 bus system. Test outcomes illustrate the developed algorithm’s efficiency.
Keywords: L-index Matrix, Jacobian Matrix, Voltage Stability, Sensitivity.
