Abstract: This paper presents an approach to the designing of a fuzzy logic-based adaptive Thyristor Controlled Series Capacitor (FLBA-TCSC) controller via minimum total energy function method to improve the power oscillation damping of a wide area power system control and enhance system stability. Within the new control strategy, using a combination of a Fuzzy logic control (FLC) and SCADA signal to establish control rules, which monitor TCSC operations with respect to various working conditions of the power system. The effectiveness of proposed approach has been validated through various simulation cases of the three phase faults at different locations of the Vietnamese power network. In order to verify the performance of the proposed control, the proposed controller is compressed with a traditional and none TCSC model. The simulation results show that the proposed control scheme improves the dynamic stability and provides the effective damping of generator angle oscillations and power ones.
