分布式资源聚合商(DRA)参与下的配电网存在阻塞管理主动性不足与跨主体协调效率低等问题,亟须研究面向多主体协同的快速调度方法。为此,文中构建了日前-日内两阶段协同调度框架。在日前阶段,对DRA进行差异化建模,引入异步并行交替方向乘子法(ADMM),通过边界功率与价格信号的有限交互,在保护各方隐私的同时实现快速求解。在日内阶段,提出基于事件驱动的滚动优化策略,设计阻塞缓解修正价格以激励并引导DRA动态调整交互电量,在必要时通过最小规模负荷削减实现阻塞消除。算例结果表明,所提两阶段协同管理方法能够有效提升配电网阻塞快速消除能力,异步并行ADMM相较传统同步并行方法计算耗时降低82.1%,验证了所提方法的可行性与优越性。
Distribution networks with the participation of distributed resource aggregators (DRAs) are confronted with problems including insufficient proactivity in congestion management and low efficiency of cross-entity coordination
which necessitates development of a rapid dispatch approach for multi-entity collaboration. To address this issue
this paper constructs a day-ahead and intra-day two-stage coordinated scheduling framework. In the day-ahead stage
this paper conducts differentiated modeling for DRAs. It introduces the asynchronous parallel alternating direction method of multipliers (ADMM). This method achieves a rapid solution while protecting the privacy of all parties through the limited interaction of boundary power and price signals. In the intra-day stage
this paper proposes an event-driven rolling optimization strategy. It designs a congestion relief correction price that incentivizes and guides DRAs to dynamically adjust the exchanged power. When necessary
it achieves congestion elimination through minimum load shedding. Case studies demonstrate that the proposed two-stage coordinated management method significantly enhances the capability of rapidly eliminating distribution network congestion. The asynchronous parallel ADMM reduces the computation time by 82.1% compared with the conventional synchronous parallel scheme
which verifies the feasibility and superiority of the proposed method.
