“…Since the behaviors of power systems are continuously changing, the centralized operation and control of such large-scale system is an extremely challenging task [2]. To alleviate these challenges, the use of advanced networking as well as information and communication technologies (ICTs) have motivated in recent years to operate and control the conventional power grid in a smarter way which is known as a peer-topeer or distributed multi-agent system (MAS) [3].…”

“…An agent-based fast valving scheme of turbines has been presented in [20] to improve the transient stability where a tracking agent tracks the generators rotor angle to determine power system instability and a control agent initiates the control action according to the output of the tracking agent. In practice, the rotor angle of generators cannot be measured conveniently [2,21]. A robotic ballcatching algorithm along with MAF is proposed in [22] for online transient stability analysis with post-fault valve control application where the algorithm is used for predicting the instability for out of synchronizing machines.…”

A transient stability control system for the electric power system composed of a prediction method and a control method is proposed based on trajectory information. This system, which is independent of system parameters and models, can detect the transient stability of the electric power system quickly and provide the control law when the system is unstable. Firstly, system instability is detected by the characteristic concave or convex shape of the trajectory. Secondly, the control method is proposed based on the analysis of the slope of the state plane trajectory when the power system is unstable. Two control objectives are provided according to the methods of acquiring the far end point: one is the minimal cost to restore the system to a stable state; the other one is the minimal cost to limit the maximum swing angle. The simulation indicates that the mentioned transient stability control system is efficient.

Summary One of the effective approaches to maintain power generation consumption balance during contingencies and therefore transient stability of the system is instantaneous rise of generation power and changing the generators excitation control system. This article proposes an auxiliary droop controller, which can replace generator main controller in order to maintain the transient stability of the system at the time of fault occurrence. Because of its linear structure, the proposed droop controller has a high response speed, so it can well supply the additional power demand given the rapid changes of the electric power demand at the time of fault occurrence. The proposed controller replaces the main controller of the generator that has the most impact on the maintaining system transient stability. Therefore, in the proposed method, first, the most efficient generator of the grid is identified using trajectory sensitivity analysis. Then, to maintain balance between power generation and consumption at the worst time of fault occurrence, the smallest amount of auxiliary controller slope is calculated through trajectory sensitivity analysis. Therefore, under any contingencies occurrence in the system, replacing the main controller with an appropriate auxiliary one will guarantee the transient stability of the system. The affectivity of the proposed method is shown using simulations on the IEEE 33‐bus test system. The simulation results show that the proposed auxiliary control method can lead to the at least 20% increase of critical clearing time (CCT) compared to the conventional droop control method. Furthermore, it is robust against the changes of inertia, up to 5%, as one of the main parameters in the first swing stability of the system.
