Simple and efficient method for steady-state voltage stability assessment of radial distribution systems
TL;DR: In this paper, a new static voltage stability index of a radial distribution system is proposed to faithfully evaluate the severity of the loading situation, thereby predicting for voltage instability at definite load value.

Optimal location of shunt FACTS devices in long transmission lines
TL;DR: In this paper, the authors investigated the validity of the above optimal location of shunt FACTS devices when the actual model of the line is considered and found that the FACTS device needs to be placed slightly off-centre to get the highest possible benefit.

Robust PI controller design for nonlinear systems via fuzzy modelling approach
TL;DR: Simulation results show that the transient stability can be improved by using a fuzzy PI controller when large faults appear in the system, compared to the conventional PI controller designed by Using a linearization method around the steady state.
