AB  - To achieve low-carbon regulation of electric vehicle (EV) charging loads under the “dual carbon” goals, this paper proposes a coordinated scheduling strategy that integrates dynamic carbon factor prediction and multi-objective optimization. First, a dual-convolution enhanced improved Crossformer prediction model is constructed, which employs parallel 1 × 1 global and 3 × 3 local convolution modules (Integrated Convolution Block, ICB) for multi-scale feature extraction, combined with an Adaptive Spectral Block (ASB) to enhance time-series fluctuation modeling. Based on high-precision predictions, a carbon-electricity cost joint optimization model is further designed to balance economic, environmental, and grid-friendly objectives. The model’s superiority was validated through a case study using real-world data from a renewable-heavy grid. Simulation results show that the proposed multi-objective strategy demonstrated a superior balance compared to baseline and benchmark models, achieving a 15.8% reduction in carbon emissions and a 5.2% reduction in economic costs, while still providing a substantial 22.2% reduction in the peak-valley difference. Its balanced performance significantly outperformed both a single-objective strategy and a state-of-the-art Model Predictive Control (MPC) benchmark, highlighting the advantage of a global optimization approach. This study provides theoretical and technical pathways for dynamic carbon factor-driven EV charging optimization.
