论文摘要
本文研究了传输切换以提高低惯性网格的同步性能的利用。功率束的同步性能首先是由$ \ Mathcal {H} _2 $线性化功率系统的规范测量的。得出了$ \ Mathcal {H} _2 $ -Norm同步性能度量标准的基于Laplacian的界限和近距公式，以揭示网络结构对同步性能的影响。此外，通过分析$ \ MATHCAL {H} _2 $ -NOMM指标对网络启发的扰动的敏感性来开发传输开关方法。使用德国的Scigrid网络证明了提出的改善同步性能的方法的有效性。
This paper investigates the utilization of transmission switching to improve synchronization performance of low-inertia grids. The synchronization performance of power girds is first measured by the $\mathcal{H}_2$ norm of linearized power systems. Laplacian-based bounds and a close-form formulation of the $\mathcal{H}_2$-norm synchronization performance metric are derived to reveal the influence of network structure on synchronization performance. Furthermore, a transmission switching approach is developed by analyzing the sensitivity of the $\mathcal{H}_2$-norm metric to perturbation of network susceptance. Effectiveness of the proposed approach to improve synchronization performance is demonstrated using the SciGRID network for Germany.
