Abstract

The increasing integration of electric vehicles (EVs) and renewable energy sources (RES) into power grids introduces significant challenges in managing dynamic energy demands and ensuring grid stability. This paper proposes a comprehensive two-level machine learning (ML) and optimisation framework for intelligent energy management in EV- and RES-integrated smart grids. In the prediction layer, supervised ML models, including Random Forest (RF) and Gradient Boosting (GB), accurately forecast EV charging demand and renewable generation. These forecasts are then fed into the optimisation layer, where a multi-objective particle swarm optimisation (PSO) algorithm minimises power losses, optimises EV charging schedules, and reduces renewable curtailment while ensuring voltage stability. The framework is evaluated on a modified IEEE 14-bus system incorporating EV charging stations, photovoltaics (PV), and wind turbines. Simulation results validate the effectiveness of the proposed framework, demonstrating a reduction in renewable energy curtailment and improved computational efficiency compared to benchmark optimisation methods.
