A Particle Swarm Optimization-Enhanced STATCOM: Fault Analysis in the IEEE 30-Bus System

This study uses MATLAB/Simulink to build an IEEE 30-bus model, simulating instability with three-phase ground faults and line tripping on key transmission lines. A Static Synchronous Compensator (STATCOM) is then installed and optimized using the Particle Swarm Optimization (PSO). Without STATCOM, post-fault voltage fluctuations are severe; with STATCOM, they are reduced. The PSO-optimized STATCOM further minimizes voltage disturbances and enhances dynamic stability. The findings confirm that PSO effectively boosts STATCOM's fault suppression capabilities.
