| 中文摘要:在多区域电网多机多进程潮流计算里，静态资源分配无法适配进程数变动与复杂电网结构，造成进程负载不均衡、分配成效不佳。鉴于此，提出融合动态负载均衡与一致性哈希稳定映射的资源动态分配算法。此算法借助适配消息传递模型，划分管理、计算进程，突破单机算力局限；经计算负载不均衡指标等操作，达成子任务资源优化动态均衡分配；以一致性哈希算法作补充，保障同一电网区域任务资源始终归属相同进程，维持计算连续性。在30节点多区域电网、16进程高并发下，该算法大幅提升了计算效率与资源利用率。 |

| Abstract:In multi regional power grid multi machine multi process power flow calculation, static resource allocation cannot adapt to changes in the number of processes and complex power grid structure, resulting in uneven process load and poor allocation efficiency. In view of this, a resource dynamic allocation algorithm that integrates dynamic load balancing and consistent hash stable mapping is proposed. This algorithm utilizes an adaptive message passing model to partition management and computation processes, breaking through the limitations of single machine computing power; By calculating load imbalance indicators and other operations, achieve dynamic balanced allocation of subtask resources optimization; Supplementing with a consistent hash algorithm, it ensures that task resources in the same power grid area always belong to the same process, maintaining computational continuity. In a 30 node multi regional power grid and 16 process high concurrency, this algorithm significantly improves computational efficiency and resource utilization. |
