Key Points

Voltage stability showed improvement by 8.6% using ANN compared to UPFC's 6.7% in steady state conditions.
Without UPFC, several bus voltages fell below 302.78 kV, indicating voltage violations demanding reactive power support.
The study utilized Particle Swarm Optimization to identify weak buses and optimize locations for voltage enhancements.
In dynamic conditions, UPFC provided stable voltage of 7.5 kV, outperforming ANN which faced significant fluctuations.
