superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...

Contingency screening for transient stability of large scale, strongly nonlinear, interconnected power systems is one of the most computationally challenging parts of Dynamic Security Assessment and requires huge resources to perform time-domain simulations-based assessment. To reduce computational cost of time-domain simulations, direct energy methods have been extensively developed. However, ...

Standard power systems are modeled using differential-algebraic equations (DAE). Following a transient event, voltage collapse can occur as bifurcation of the load flow solutions. This results from states' trajectories reaching singular surface where causality is lost. Preventive controls such changes in AVR setpoints need to be taken enhance stability. To determine which actions most effective...
