Enhancing Transient Stability of a Two-Machine Power System Under Fault Conditions Using Static VAR Compensator

This project explores advanced techniques to enhance transient stability in a two-machine power system by integrating a modern Power System Stabilizer (PSS) and a state-of-the-art Static VAR Compensator (SVC) to manage fault-induced disturbances. Leveraging cutting-edge control strategies, the PSS is designed to mitigate low-frequency oscillations caused by severe three-phase and various types of faults, while the SVC dynamically optimizes reactive power flow by injecting or absorbing reactive power in real time. MATLAB Simulink simulations, combined with entropy-based stability analysis, quantify the system's response under various fault conditions. Entropy values, representing the degree of randomness in system oscillations, are used to evaluate the effectiveness of these solutions. Comparative analyses with and without PSS and SVC demonstrate their synergistic impact in improving damping performance and reducing instability. This study confirms that modern PSS and SVC technologies, combined with advanced fault-tolerant control algorithms, are critical for achieving robust transient stability in contemporary power systems.
