Abstract: The reliability and efficiency of power transmission in Nigeria's 330kV network are significantly threatened by voltage instability, particularly under conditions of heavy load, fault disturbances, and network contingencies. This study presents an intelligence-based Super Capacitor (IBSC) technique as a strategic solution for enhancing voltage stability across the transmission network. The proposed method integrates advanced artificial intelligence algorithms with high-performance energy storage devices (super capacitors) to dynamically support voltage levels, compensate for reactive power, and mitigate transient disturbances. Simulation models developed in MATLAB/SIMULINK environment demonstrate that the intelligence-based super capacitor system provides a rapid response to voltage fluctuations and improves system resilience during voltage sag events. Comparative analysis with traditional compensation techniques reveals superior performance of the IBSC approach in maintaining voltage profiles within acceptable thresholds of 0.95 to 1.05 per unit volts. The research highlights the potential of intelligent energy storage integration in modern power systems and recommends the adoption of the proposed technique for improved voltage regulation, grid stability, and overall power system reliability in Nigeria’s transmission network. The conventional faulty bus1 per unit volts was 0.93p.u.v. This caused an intermittent power supply in the transmission network. On the other hand, when an intelligent based super capacitor was integrated into the system, it instantly stabilized the voltage to 1.028p.u.v. And the conventional faulty bus 25 per unit volt was 0.947p.u.v, thereby caused consistent power failure. Meanwhile, when an intelligent-based super capacitor was imbued into the system, it simultaneously attained voltage stability of 1.04p.u.v, thereby enhancing a consistent power supply in the transmission network. Finally, with these results obtained, it showed that the average percentage improvement in voltage stability in the Nigerian 330kV transmission network when an intelligent-based super capacitor was integrated into the system was10%.
