A Novel Algorithm for Capacitor Placement to improve Voltage stability of Radial and Meshed Power Systems

G Rajendar, Basavaraja Banakara


The objective of this paper is to present a novel method for determining the optimum location and amount of reactivepower to be injected to improve the voltage stability of entire power system or set of buses that are prone to voltageinstability. A new sensitivity matrix named L-Index sensitivity matrix is been proposed and the same is consideredfor identifying the buses, at which the reactive power is to be injected. The proposed procedure has been tested forpractical examples of radial networks and IEEE-14 bus system. Test results demonstrate the effectiveness of thedeveloped algorithm.

Keywords: L-index matrix, voltage stability, Jacobian matrix, sensitivity
