论文摘要
电力系统分散优化的最复杂因素之一是电源流程方程的建模。 DC功率流的现有配方要么具有有限的可伸缩性或非常密集且非结构化，因此它们不适合大规模分散研究。在这项工作中，我们基于稀疏的注射转移因子提供了一种新颖的DC功率流式公式，该偏移偏移因子具有可分解的块 - 二重奏结构，适合大型系统，并且可以有效地满足N-1的安全要求。多区域安全约束的单位承诺问题的基准表明，拟议的配方可以使用多达6,515辆公交车可靠，有效地解决实例，而没有收敛或数值问题。
One of the most complicating factors in decentralized optimization for power systems is the modeling of power flow equations. Existing formulations for DC power flows either have limited scalability or are very dense and unstructured, making them unsuitable for large-scale decentralized studies. In this work, we present a novel DC power flow formulation, based on sparsified injection shift factors, which has a decomposable block-diagonal structure, scales well for large systems, and can efficiently handle N-1 security requirements. Benchmarks on Multi-Zonal Security-Constrained Unit Commitment problems show that the proposed formulation can reliably and efficiently solve instances with up to 6,515 buses, with no convergence or numerical issues.
