配电网中的分布式能源（DER）具有为输电系统提供容量储备的巨大潜力。在这种情况下，本文重点优化的聚合的灵活性DER在配电网络中，涉及网络范围内的电压约束，和个别设备的操作约束。预定的任务首先制定为一个凸规划，然后通过严格的凸分析突出的几个关键属性的基本最优聚合解决方案。利用特殊的问题结构，进一步开发了一个分散的求解器，以有效地找到最佳的聚合轨迹与有限的通信。IEEE 37节点的性能测试进行了验证的理论研究结果，并证明了各种网络配置的影响。
Distributed energy resources (DERs) in distribution networks have great potential for providing capacity reserves to the transmission systems. In this context, this paper focuses on optimizing the aggregated flexibility of DERs in power distribution networks, involving both network-wide voltage constraints, and individual device operating constraints. The intended task is first formulated as a convex program, and several critical properties of the underlying optimal aggregation solution are then highlighted via rigorous convex analysis. Leveraging the special problem structure, a decentralized solver is further developed to efficiently find the optimal aggregation trajectory with limited communication. Performance tests on the IEEE 37-bus benchmark are conducted to verify the theoretical findings and demonstrate the impact of various network configurations.
