统一同步电网拓扑的稳态稳定性分析
A steady-state stability analysis of uniform synchronous power grid topologies
摘要：
Motter等人导出了一个实值主稳定性函数，该函数确定给定电网是否渐近稳定以及在多大程度上渐近稳定。Stright和Edrington在网格的组件上采用了某些一致性假设，并证明了使用这些组件获得的拓扑结构的差异如何影响最终网格的稳定性。在这项工作的基础上，我们通过模拟显示的物理意义的稳定性，而不是不稳定性。我们表明，稳定的拓扑结构，增加稳定性可以对应于发电机转矩脉动降低。我们还描述了如何在电网拓扑结构的一些基本变化可以影响稳定值。某些抽象的循环网格的已知稳定性值被用来量化的稳定性增强互连密度的增加。
英文摘要：
Motter et al. derived a real-valued master stability function which determines whether and to what degree a given power grid is asymptotically stable. Stright and Edrington adopted certain uniformity assumptions on a grid's components and demonstrated how differences in topologies obtained using these components can affect the stabilities of the resulting grids. Building on this work, we show via simulations the physical significance of stability as opposed to instability. We show that for stable topologies, increased stability can correspond to decreased generator torque ripple. We also describe how some elementary changes in grid topology can affect stability values. Known stability values for certain abstract circulant grids are used to quantify stability enhancement as interconnection density increases.
