The load flow analysis is an important method for the power system analysis and designing. This analysis is carried out at each and every state of planning, operation, control and economic scheduling. In this paper, the authors have focus on the finding of most sensitive node in IEEE- 14 bus systems. Simulation is carried out at PSAT Matlab toolbox which includes a complete set of user-friendly graphical interface and a simulink-based editor for one-line network diagrams which utilizes the L-index method and FVSI for voltage stability analysis and sensitive nodes determination.
