Discovering EV Charging Site Archetypes Through Few Shot Forecasting: The First U.S.-Wide Study
- 结合聚类与少样本预测，识别充电站行为模式
- 新模型在未知站点上预测准确率显著优于通用模型
- 适合能源运营商和城市规划者用于优化充电网络
交通电气化依赖于电动汽车的广泛普及，这需要准确理解充电行为以确保基础设施经济高效且电网韧性。现有研究受限于小规模数据集、简单基于邻近性的时序建模，以及对运营历史短站点的泛化能力弱。本文提出一种融合聚类与少样本预测的框架，利用大规模充电需求数据发现站点类型。结果表明，针对不同类型的专家模型在未见站点上的需求预测表现优于全局基线模型。通过将预测性能作为基础设施分段依据，生成可操作的洞察，帮助运营商降低成本、优化能源与定价策略，并支持实现气候目标所必需的电网韧性。
原文摘要 · Abstract (English)
The decarbonization of transportation relies on the widespread adoption of electric vehicles (EVs), which requires an accurate understanding of charging behavior to ensure cost-effective, grid-resilient infrastructure. Existing work is constrained by small-scale datasets, simple proximity-based modeling of temporal dependencies, and weak generalization to sites with limited operational history. To overcome these limitations, this work proposes a framework that integrates clustering with few-shot forecasting to uncover site archetypes using a novel large-scale dataset of charging demand. The results demonstrate that archetype-specific expert models outperform global baselines in forecasting demand at unseen sites. By establishing forecast performance as a basis for infrastructure segmentation, we generate actionable insights that enable operators to lower costs, optimize energy and pricing strategies, and support grid resilience critical to climate goals.
