确保可持续能源供应需要维持电网稳定性。转子动力学由摇摆方程描述，该方程为二阶Kuramoto模型，具有功率与总耦合强度间的相关性。然而，同步集群成核与传播的微观机制仍知之甚少。利用基于经验电网数据和Adhoc势方法的最小模型，我们揭示了两种不同的种子集群类型及传播路径：一种是位于功率分布中心、通过转子向尾部增殖的种群驱动型种子集群；另一种是对于对称分布、通过集群合并向中心传播的耦合驱动型种子集群，位于功率分布尾部。这些差异产生了不同的序参量模式，而惯性决定种子集群是否以不同角速度持续存在。相同的传播路径也适用于外部干扰后的恢复过程。我们进一步确认，相同的选择-持续规则在数据导出的欧洲电网退火表示中成立。因此，我们的结果可为维持电网稳定运行的策略提供信息。更广泛地说，我们基于路径的框架通过强调集群形成与恢复的动力学，而非仅依赖静态标准，重新定义了同步研究。
英文摘要
Ensuring a sustainable energy supply requires maintaining power-grid stability. Rotor dynamics are governed by the swing equation, which takes the form of a second-order Kuramoto model with a correlation between power and total coupling strength. Yet the microscopic mechanisms that nucleate and propagate synchronized clusters remain poorly understood. Using a minimal model motivated by empirical grid data and the \Adhoc potential method, we reveal two distinct seed cluster types and propagation pathways: a population-driven seed cluster at the center of the power distribution propagating to its tails by rotor accretion, and, for a symmetric distribution, coupling-driven seed clusters at its tails propagating inward to the center by cluster merger. These differences generate distinct order-parameter patterns, while inertia controls whether the seed clusters persist with distinct angular velocities. The same propagation pathways also govern recovery following external disturbances. We further confirm that the same selection--persistence rule holds in data-derived annealed representations of European power grids. Therefore, our results can inform strategies for sustaining stable power-grid operation. More generally, our pathway-based framework reframes synchronization by emphasizing the dynamics of cluster formation and recovery rather than relying solely on static criteria.
