The stability of the power system is essential to ensure its proper functioning. In recent years, Flexible AC Transmission Systems have been considered as one of the effective methods to improve the control ability of the power system and power transition constraints. One of the devices of the parallel flexible alternating current transmission systems is STATCOM which can improve the power system dynamic and transient voltage stability. In this study, a new method for designing the damping controller was proposed to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller problem in a wide area of the system function was considered as an optimization problem with multi-purpose objective function. Also, the Honey Bee Mating Optimization Algorithm was used to determine its parameters.

In general, the stability of the power system can be considered a feature of the system that enables it to remain in equilibrium under normal conditions and regain a different acceptable state if affected by disturbance. Instability in a power system may take many forms, depending on the composition of the system and its operating modes. In order to evaluate the proposed method in damping transient fluctuations and network stability, a study has been carried out on a typical network. Since the topic of the article is in the field of transient stability, in part of the paper, braking resistance modeling in transient stability studies has been investigated. In the section on brake resistor control, brake resistor control is introduced by a switched Thyristor, using the trapezoidal method. Finally, the simulation results of the studied network are presented with the presence of TCBR and its capability of damping in the desired network.
