The rapid proliferation of electric vehicles (EVs) has created unprecedented challenges for power grid infrastructure, particularly in managing the high-power demands of fast-charging stations. This research presents a novel approach to dynamic load balancing in EV fast-charging stations through machine learning integration with smart grid systems. The study develops and validates a predictive model that combines Long Short-Term Memory (LSTM) networks, Random Forest, and Gradient Boosting algorithms to optimize power distribution while maintaining grid stability. Using real-world data collected from 50 fast-charging stations across urban and suburban locations over a 12-month period, our proposed system demonstrates significant improvements over traditional methods. The results show a 27% improvement in load distribution efficiency and a 15% reduction in peak demand. Furthermore, the system achieves 92% accuracy in demand prediction and reduces charging waiting times by 8%. Grid stability metrics also improved substantially, with a 30% reduction in voltage fluctuations and a 20% improvement in power factor. The economic impact analysis reveals a 23% reduction in operational costs and a 35% improvement in energy utilization. The system's integration with smart grid infrastructure demonstrates robust scalability and adaptability to varying demand patterns. These findings suggest that machine learning-based load balancing can significantly enhance the reliability and efficiency of EV charging infrastructure while supporting grid stability. The proposed approach provides a promising foundation for future developments in smart charging systems, particularly in the context of increasing EV adoption rates and the growing need for sustainable transportation infrastructure.
