Detailed Documentation

This paper examines the effect of Thyristor-Controlled Series Capacitors (TCSC) on subsynchronous resonance (SSR) bifurcations in power systems. First, we introduce fundamental concepts of power systems and SSR phenomena. Next, we explore power system stability and subsynchronous resonance issues under TCSC control, discussing implementation aspects such as firing angle control algorithms and impedance modulation techniques. We also analyze TCSC's operational principles and application scenarios, including its impact on power system dynamics through simulations using tools like MATLAB/Simulink for eigenvalue analysis and time-domain simulations. Finally, we present the experimental methodology and results of this study, incorporating numerical bifurcation analysis codes to better understand TCSC's influence on SSR bifurcation behavior in electrical networks.
