论文摘要
网络拓扑对电源系统的运营性能有重大影响。尽管广泛的研究工作已致力于优化网络拓扑以改善各种系统性能，但如何从初始拓扑过渡到所需的最佳拓扑的问题需要研究。为了解决这个问题，我们提出了最佳拓扑过渡（OTT）的概念。这旨在找到从初始拓扑到所需的终端拓扑的拓扑过渡轨迹，从而优化某些过渡性能并满足操作约束。在某些假设下，OTT问题进一步提出为混合企业计划。接下来，我们提出了能够同时优化网络拓扑及其过渡轨迹的过渡装置拓扑优化的制定。考虑到直接求解混合企业程序的时间复杂性，开发了一种有效的问题特定解决方案算法。最后，数值研究证明了与临时过渡轨迹相比，所提出的OTT和转型式拓扑优化模型的有效性以及所获得的最佳过渡轨迹的优越性。
Network topology has significant impacts on operational performance of power systems. While extensive research efforts have been devoted to optimization of network topology for improving various system performances, the problem of how to transition from the initial topology to the desired optimal topology requires study. To address this problem, we propose the concept of optimal topology transition (OTT). This aims to find the topology transition trajectory from an initial topology to a desired terminal topology, which optimizes certain transition performance and satisfies operational constraints. The OTT problem is further formulated as a mixed-integer program under certain assumptions. Next, we propose the formulation of transition-embedded topology optimization that is capable of optimizing network topology and its transition trajectory simultaneously. Considering the time complexity of directly solving the mixed-integer programs, an efficient problem-specific solution algorithm is developed. Finally, numerical studies demonstrate the effectiveness of the proposed OTT and transition-embedded topology optimization models, as well as the superiority of the obtained optimal transition trajectories compared to ad hoc transition trajectories.
