Abstract: To optimize the grid fluctuation and safety issues caused by high penetration charging of electric vehicles, a novel distribution network capacity planning model is proposed. This model fused traffic-coupled model and dual-layer control strategy for charging scheduling, optimizing the power balance during peak electricity usage and charging station energy storage issues. Then, a stable and efficient distribution network power supply system is established. Experimental results demonstrate that our model achieves a comprehensive energy efficiency of 84.19%, with peak power loads controlled below 300 kW, surpassing similar algorithms. Moreover, it provides a scientifically grounded numerical range for practical planning.
