在电动汽车业务生态系统中,因电网企业、交管部门、充电站运营商、用户等多方主体间存在数据孤岛和信任壁垒,影响了系统整体优化。为此,文中设计并实现了一个基于可信执行环境(TEE)的协作技术。首先,根据业务各参与方特点,设计了以TEE技术为核心的可信计算底座和适配各类模型的联邦学习算法,以保障各参与方的敏感数据可在本地进行局部模型训练,并由联邦学习发起方聚合全局智能模型;然后,设计了基于动态贡献度量的模型聚合权重更新方法,解决了多方协作的利益平衡问题;最后,基于公开数据构建了平行对比仿真场景,以验证数据协作效果。仿真结果表明,通过数据的安全交互,所提技术能够有效引导用户参与车网互动,显著平滑电网负荷并提升充电站利用率,实现碳积分增长。
In the electric vehicle business ecosystem
data silos and trust barriers among multiple stakeholders including power grid enterprises
traffic management departments
charging station operators and users hinder the overall optimization of the system. To address this issue
this paper designs and implements a collaboration scheme based on the trusted execution environment (TEE). First
considering the characteristics of all business participants
a trusted computing infrastructure centered on TEE and federated learning algorithms adaptable to various models are devised. This ensures that each participant can train local models on sensitive data locally
while the federated learning initiator aggregates the global intelligent model. Second
a model aggregation weight updating method based on dynamic contribution measurement is proposed to balance the benefits in multi-party collaboration. Finally
parallel comparative simulation scenarios are constructed using public datasets to verify the performance of data collaboration. Simulation results demonstrate that with secure data interaction
the proposed scheme can effectively incentivize users to participate in vehicle-to-grid (V2G)
noticeably flatten power grid load profiles
improve charging station utilization
and increase carbon credits.
