Abstract

A new voltage stability index is proposed to identify nodes that are on the verge of voltage collapse. The value of the proposed voltage stability index is calculated at each node of the network. The results are compared with the other known methods of voltage sensitivity indices and found to be satisfactory. The authors present a comprehensive comparison with the recently proposed voltage stability index by Chakravorty and Das and carry out a detailed analysis of effects of different load models on voltage computation and voltage stability.
