Fuzzy Logic based Stability Index Power System Voltage Stability Enhancement

S.Senthil Kumar, P.Ajay-D-Vimal Raj, Member, IACSIT

Abstract—This paper work aims the predication of steady state voltage stability conditions in a transmission network. The voltage stability is checked by formulating an (L) index and the corresponding uncertainties input parameters are efficiently modeled in terms of fuzzy sets by using triangular membership function. The proposed technique will be highly useful to ensure voltage security of power system by predicting the nearness of voltage collapse with respect to the existing load condition. This will in turn help us in determining the maximum load ability of the given system without causing voltage instability. The validity of the technique is tested on a sample 5-bus system and IEEE 14-bus system using software simulation. The results are provided for the feasibility of the technique includes fuzzy load flow solution for base and critical cases. This method can be applied both for off-line as well as on-line applications.

Index Terms—Fuzzy logic, Power system enhancement, Stability index, Voltage Stability.
