Transient stability of power systems is becoming increasingly important because the growing integration renewable resources. These resources lead to a reduction in mechanical inertia but also provide increased flexibility frequency responses. Namely, their electronic interfaces can implement almost arbitrary control laws. To design these controllers, reinforcement learning (RL) has emerged as p...

This paper proposes a new method for transient stability analysis for electric power systems. Different from existing methods, a minimization problem is formulated for obtaining critical conditions for transient stability. The method is based on the computation of a trajectory on the stability boundary, which is referred to as critical trajectory in this paper. The critical trajectory is define...

Transient stability problem for multi-machine infinite bus system with the generator excitation was addressed via the non-certainty equivalent nonlinear re-parameterization method. The system need not to be linearized. The damping coefficient uncertainty was considered. A non-certainty equivalent excitation controller and a novel parameter updating law were obtained simultaneously via adaptive ...

The effect of line impedance compensation mode of series inverter along with the voltage regulation mode of shunt inverter of UPFC is investigated for transient stability improvement of Single Machine Infinite Bus System. Four control modes like perpendicular voltage or phase angle control etc have also been discussed. The effect of line impedance mode on critical clearing time with a three pha...
