Overview

This approach improves voltage stability in Nigeria's power system, highlighting UPFC and ANN's effectiveness.

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.
