摘要

相当大的扰动可能会将电网从稳定同步状态推向不理想的状态。通过研究电网在这种扰动下的稳定性,找出电网的漏洞,有助于防止未来发生大停电。我们使用两个稳定性度量 $unicode{x2014}$stability bound(处理系统的渐近行为)和survivability bound(处理系统的瞬态行为)来提供有关破坏系统稳定的扰动强度的信息。利用这些稳定性度量,我们发现类三维结构中的某些节点具有较低的渐近稳定性,而具有高连接数的节点通常具有较低的瞬态稳定性。

How Network Topology Affects the Strength of Dangerous Power Grid Perturbations
Reasonably large perturbations may push a power grid from its stable synchronous state into an undesirable state. Identifying vulnerabilities in power grids by studying power grid stability against such perturbations can aid in preventing future blackouts. We use two stability measures $\unicode{x2014}$ stability bound, which deals with a system's asymptotic behaviour, and survivability bound, which deals with a system's transient behaviour, to provide information about the strength of perturbations that destabilize the system. Using these stability measures, we have found that certain nodes in tree-like structures have low asymptotic stability, while nodes with a high number of connections generally have low transient stability.
