摘要

电动汽车充电需求的准确预测对缓解电网压力至关重要。针对现有预测方法在处理非独立同分布数据时收敛慢、易受不可靠节点影响的问题，本文提出一种双层可信联邦学习(Double-Layer Credible Federated Learning

DCFL)能量需求预测策略。该方法利用启发式关联规则自动挖掘充电信息，无需额外数据采集；通过权值损失变化筛选良性本地因子以加速收敛并抵御不可靠节点干扰；引入多通道注意力机制设计损失函数与加权聚合方式。实验结果表明，相比传统联邦学习方法，本方法训练时间减少71%，收敛速度提升17.6%，在预测准确度和收敛效率方面均有显著优势。

Abstract

Accurate prediction of electric vehicle charging demand is crucial for alleviating pressure on the power grid. To address the issues of slow convergence and vulnerability to unreliable nodes in existing prediction methods when processing non-independently and identically distributed (non-IID) data

this paper proposes a Double-Layer Credible Federated Learning (DCFL) strategy for energy demand prediction. The proposed method employs heuristic association rules to automatically mine charging information without requiring additional data collection. It selects benign local updates based on weight loss variation to accelerate convergence and resist interference from unreliable nodes. Furthermore

a multi-channel attention mechanism is introduced to design the loss function and the weighted aggregation scheme of federated learning. Experimental results demonstrate that

compared with traditional federated learning methods

the proposed method reduces training time by 71% and increases convergence speed by 17.6%

showing significant advantages in both prediction accuracy and convergence efficiency.
