    Stabilizing control for power system stability has been applied to generators equipped with excitation controller and speed governor. Recently, power electronics-based control devices have been the focus of research and development for the improvement of transient stability. Power electronics control devices are utilized for control of the power flow on a transmission line or the reactive power in a power system. In that case, they have no constraint of setting point in a power system. On the other hand, the total number of these devices to be equipped has economical constraints, because their prices are very expensive; therefore, the allocation problem of these controllers is worth studying. This paper proposes an approach to determine the numbers and locations of Thyristor-controlled series capacitor (TCSC) in a multi-machine power system. The index of optimal allocation of the controllers is the power system stability. First, the steady-state stability is considered, and then the transient stability is examined to find a robust allocation of the TCSC controllers.
