论文摘要
本文提出了一种新的方法，可以使用纠正网络重新配置（CNR）来处理安全受限的单元承诺（SCUC）中的计算复杂性，以利用传输网络的灵活性。通过分解SCUC/SCUC-CNR公式，然后快速筛选非关键亚问题，可以考虑可伸缩性。将其与SCUC和SCUC-CNR的广泛制剂进行了比较，以显示提出的典型分解和加速分解方法的优势。 IEEE 24总线系统上的仿真结果表明，所提出的方法在没有溶液质量损失的情况下更快。与各自的广泛的配方和典型的分解方法相比，提出的大型电源系统在IEEE 73-BUS系统和波兰系统的可伸缩性测试中具有出色的性能，可以实现提出的加速分解方法。总体而言，动态的宿舍后网络可以大大减轻网络拥堵并导致最佳成本较低。
This paper presents a novel approach to handle the computational complexity in security-constrained unit commitment (SCUC) with corrective network reconfiguration (CNR) to harness the flexibility in transmission networks. This is achieved with consideration of scalability through decomposing the SCUC/SCUC-CNR formulation and then fast screening non-critical sub-problems. This is compared against the extensive formulations of SCUC and SCUC-CNR to show the advantages of the proposed typical-decomposition and accelerated-decomposition approaches to SCUC and SCUC-CNR respectively. Simulation results on the IEEE 24-bus system show that the proposed methods are substantially faster without the loss in solution quality. The proposed accelerated-decomposition approaches can be implemented for large power systems as they have great performance in the scalability tests on the IEEE 73-bus system and the Polish system when compared against the respective extensive formulations and typical-decomposition approaches. Overall, a dynamic post-contingency network can substantially alleviate network congestion and lead to a lower optimal cost.
