Fast calculation of a voltage stability index

IEEE Transactions on Power Systems, 1992
The minimum singular value of the power flow Jacobian matrix has been used as a static voltage stability index, indicating the distance between the studied operating point and the steady-state voltage stability limit. A fast method to calculate the minimum singular value and the corresponding (left and right) singular vectors is presented.

Fast calculation of a voltage stability index of power systems

IEEE Transactions on Power Systems, 1997
The minimum singular value of the Jacobian matrix of the load flow equation may have been preferred as an indicator of voltage collapse when the static voltage stability of power systems is studied. In this paper, the authors propose a highly efficient algorithm to calculate the smallest singular value of a Jacobian matrix of the load flow equation by ...

Detection of weak bus through Fast Voltage Stability index and inherent structural characteristics of power system

2015 4th International Conference on Electric Power and Energy Conversion Systems (EPECS), 2015
Modern power system is large, complex and characterized by continuous increase in electrical load demand. As a result, the system is stressed to operate closer to stability limit and this may result in voltage collapse. Therefore, it becomes imperative to implement techniques for detecting collapse in bus bar or lines before its occurrence in the power
