Synchronization-Safe Dynamic Microgrid Formation for DER-Led Distribution System Restoration With Constraint-Aware Graph Learning

🤖 AI 总结 要点：本文提出一种同步安全的动态微网形成（SSDMGF）框架，用于高渗透分布式能源资源（DER）配电系统的快速恢复。通过定义系统模式和系统类别来描述具有演变边界的恢复状态，并显式限制模式和类别的转换以确保同步安全。进一步设计了一个约束感知的时空图卷积网络（STGCN），其中同步相关约束被嵌入到基于直通估计器（STE）的可微可行性求解层，以生成高质量的热启动解。在改进的 IEEE 123 节点馈线上的案例研究表明，该方法既保证了同步安全的微网形成，又显著提升了恢复性能并实现了显著的计算加速。 关键数据：— 技术路径：先定义系统模式与类别并限制其转换以保证同步安全，然后构建约束感知的时空图卷积网络，将同步约束通过可微分层（基于 STE）嵌入网络中，用于生成温启动解以降低后续优化求解时间。 工程权衡：方法依赖于高质量的图结构和充分的离线训练数据，模型复杂度增加可能带来额外的存储和推导开销；严格的同步安全约束虽提升安全性但可能限制微网形成的灵活性，需在安全性与求解速度之间进行权衡。
