A Novel Distributed Parallel Computing Method for TTC Evaluation with Transient Stability Constraints

在预想故障集下,针对大规模互联电力系统的暂态稳定约束最大输电能力(TTC)评估问题,提出了一种基于任务级的分布式并行计算方法——优化的工作站群的计算方法。该分布式并行计算方法把异构分布式计算资源加以融合,实现有效的动态负载均衡,从而最大化利用系统的整体计算性能,具有良好的动态扩展性与容错性。应用所提出的方法对具有1101个母线和97台发电机的中国某实际电网进行了测试。测试结果表明,该分布式并行计算方法是实用有效的。

A task-level-based distributed parallel computing method, called the optimized workstation cluster computing method for total transfer capability （TTC） evaluation with transient stability constraints of the large-scale interconnected power grid and a specified contingency set is proposed. This distributed parallel computing method can effectively integrate the heterogeneous distributed computing resources and implement the dynamic load balancing to make full use of the whole system computing capability with good performance of dynamic scalability and fault tolerance. A case study is made on an actual 1 101- busbar 97-generator power grid of China, the experimental results of which show that the distributed parallel computing method proposed is practical and effective.
