Jitendra Singh Bhadoriya, Chandra Kumar Daheriya

Voltage instability and voltage collapse have been considered as a series threat to power system operation. Fast response and accurate voltage stability indications in power systems are still a challenging task to achieve, particularly when power systems operated close to its transmission capacity limits. A successful avoidance of system collapse is based on method accuracy and its low computation time. This paper presents simple, fast and efficient indices for analyzing power system voltage stability and successfully predicting system voltage collapse for sensitive voltage node methods .A review have been made on different deterministic methods used for finding sensitive node for voltage collapse. The effectiveness of methodology are summarized including advantage and disadvantage over other stochastic methods.
