    Low-frequency oscillations observed on trunk transmission systems have been the subject of studies in many areas of operation, control, and devices. While stabilizing controllers such as excitation controllers and speed governors have been widely applied to power systems, power electronics-based control devices have been the focus of research and development in recent years in improving transient stability. Such control devices are utilized in controlling real and reactive power flows in a transmission line or in a power system. However, there is a limit to the number of such devices to install; therefore, a proper allocation of these controllers is an important and practical issue. This paper proposes an approach to determine the number and location of Thyristor-Controlled Series Capacitors (TCSCs) to mitigate low-frequency oscillation in an interconnected power system.
