摘要
分布式计算是解决大规模电力系统仿真算力需求的有效方法。然而分布式计算容易受到少数问题节点性能下降所带来的负面影响,从而导致算法的计算效率严重下降。本文提出基于编码技术的仿真平台分布式计算方法,从而规避上述负面影响。首先,对构建了大规模电力系统仿真的计算任务模型;然后,通过理论分析确定了其中最优编码率的取值范围;最后,仿真分析结果表明,应用编码技术并采用合适的编码率,可有效提高大规模电力系统仿真中分布式算法的运行效率。
Abstract
Distributed computing is an effective method to provide the computing sources for large-scale electric power system simulations. However, the performance degradation of some computing nodes will negatively impact distributed computing of the entire system simulations, which leads to a serious decline in the computational efficiency of algorithms. This paper investigates the simulation platforms based on coding techniques to avoid the negative effects in the distributed computing system. First, we model the computing tasks of the large-scale electric power system simulations. Then, we theoretically analyze the range of the optimal coding rate. Finally, from the simulation results, we conclude that coding with the appropriate coding rate can effectively improve the computational efficiency of the distributed computing of the large-scale electric power system simulations.
