高性能计算技术和平台的发展为实时甚至更快地实现电力系统仿真提供了许多机会。一种方法是使用Parareal in Time框架。Parareal算法通过在时间上将模拟运行分解为整个模拟区间上的粗略模拟和通过粗略模拟链接的序列子区间上的精细模拟，显示出良好的理论模拟加速比。然而，研究发现，为了充分发挥Parareal算法的潜力，需要降低粗求解器的时间开销。本文研究了用简化发电机模型实现粗解器的并行实现，并报告了在IEEE 39节点系统和327发电机2383节点波兰系统模型上的测试结果。
The development of high-performance computing techniques and platforms has provided many opportunities for real-time or even faster-than-real-time implementation of power system simulations. One approach uses the Parareal in time framework. The Parareal algorithm has shown promising theoretical simulation speedups by temporal decomposing a simulation run into a coarse simulation on the entire simulation interval and fine simulations on sequential sub-intervals linked through the coarse simulation. However, it has been found that the time cost of the coarse solver needs to be reduced to fully exploit the potentials of the Parareal algorithm. This paper studies a Parareal implementation using reduced generator models for the coarse solver and reports the testing results on the IEEE 39-bus system and a 327-generator 2383-bus Polish system model.
