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.

On-line voltage stability based contingency ranking using fast voltage stability index (FVSI)

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
Voltage instability is one phenomenon that could happen in a power system due to its stressed condition. The result would be the occurrence of voltage collapse which leads to total blackout to the whole system. Therefore voltage collapse prediction is important in power system planning and operation so that the occurrence of voltage collapse due to ...
