Abstract

Summary

Modern power systems are increasingly exposed to more changing loads and nonlinear operating conditions, which can affect the performance of conventional power factor correction systems. This study presents an enhancement of an adaptive power factor correction method for improved performance in dynamic and complex power systems using an intelligently controlled ultracapacitor. The study had established six performance constraints related to the adaptive power factor correction system; response latency, compensation error, harmonic resonance, step resolution, voltage stability, and thermal working temperature. A quantitative analysis of the conventional and the improved systems was carried out for response latency, step resolution, and thermal operating temperature using the results of the simulations. A conventional Simulink model was developed to establish the baseline performance of the system. A fuzzy inference-based rule base was subsequently developed to determine appropriate corrective actions based on the identified system conditions, after which an artificial neural network was trained using the developed rules. An ultracapacitor model was then developed and integrated with the intelligent control scheme and the conventional adaptive power factor correction model. Simulation results showed that the response latency decreased from 55 ms for the conventional system to 48.28 ms with the intelligently controlled ultracapacitor, representing an improvement of approximately 12.2%. The step resolution decreased from 14 kVA to 12.28 kVA, corresponding to an improvement of approximately 12.3%, while the thermal operating temperature decreased from 58 0C to 50.8 0C, representing an improvement of approximately 12.4%. The results indicate that integrating intelligent control with an ultracapacitor can improve selected dynamic and operating characteristics of the adaptive power factor correction system. The proposed approach therefore provides a promising simulation-based framework for improving adaptive power factor correction performance under dynamic operating conditions.
