A Robust Optimization Method for Dynamic Operating Envelope Coordination in Distribution Networks

In this paper, we propose a Dynamic Operating Envelope (DOE) coordination method for aggregators in distribution networks (DNs). While the DOE acts as a time-varying power export limit to ensure the DN’s integrity, existing aggregator-agnostic allocation overlooks the surplus of aggregators. To address this limitation, our approach allows aggregators to cooperatively adjust DOEs by solving a two-stage robust optimization and settling payments between themselves. The coordination problem is solved by the column-and-constraint generation (C&CG) algorithm, ensuring that any power injection within the adjusted DOE maintains the network integrity. Consequently, the aggregators’ total surplus increases. A 4-bus system case study demonstrates the effectiveness of the proposed method.
