Analysis of a new voltage stability pointer for line contingency ranking in a power network

Improper management of reactive power in a network could lead to voltage instability. This paper presents well-detailed study on instability due violation equilibrium and introduces new stability pointer (NVSP). The proposed NVSP is developed from reduced 2-bus interconnected predict the sensistivity variation. simulation results MATLAB were evaluated IEEE 14-bus test system. contingency ranking was achieved by varying load buses its maximum loading limit. point taken at each bus critical lines ranked according their vulnerability collapse. compared with other notable indices. prove that an essential tool predicting
