A New Technique to find the effect of Active Power Loading on Voltage Stability and Algorithm to improve Voltage Stability of Radial and Meshed Power Systems

Abstract

This paper will analyze the impact of active power on voltage stability of radial and meshed systems and a new algorithm is proposed which would indicate the amount and location at which the active power is to be reduced to improve the voltage stability of entire power system or set of buses that are prone to voltage instability. A new sensitivity matrix named Active Power L-Index sensitivity matrix is been proposed. The proposed approach is simple and easy to be implemented into large power systems. The proposed approach has been applied to several Indian rural distribution networks and IEEE 14-bus test system which demonstrated applicability of the proposed approach.
