TCSC has been proposed to enhance the voltage stability by changing the reactive power distribution in the power system. Authors have discussed the effect of TCSC on steady state voltage stability and small-signal voltage stability. This paper discusses the TCSC’s enhancement on transient voltage stability. A TCSC model that is suitable for transient voltage stability analysis is proposed. This...

Distribution systems are the major interface between electricity consumer and electrical transmission system. Requisite amount of planning is necessary for these to be in order as they vast complex. An important concern on operation distribution its voltage stability. Placing Distributed Generation (DGs) system can address concerns a better way. The location rating DGs going have deep impact pr...

Abstract Voltage instability is a serious phenomenon that can occur in power system because of critical or stressed conditions. To prevent voltage collapse caused by such instability, accurate prediction necessary for planning and operation. This paper proposes novel index ( NCPI ) to assess the stability conditions lines. The effectiveness applicability proposed are investigated on IEEE 30-bus...

This paper presents a simple method for estimation of additional load as a factor of the existing load that may be drawn before reaching the point of line maximum loadability of radial distribution system (RDS) with different realistic load models at different substation voltages. The proposed method involves a simple line loadability index (LLI) that gives a measure of the proximity of the pre...
