摘要(Abstract)：

随着配电网元件种类日益丰富和分布式电源渗透率不断提高,网络动态过程更加多样化,配电网暂态仿真的难度进一步加大。针对目前有源配电网并行暂态仿真方法未考虑元件动态响应速度对仿真计算量的影响和仿真步长需求的问题,提出了一种基于优化分网策略的自适应变步长多速率并行仿真方法。考虑不同元件暂态响应速度和计算量的差异,提出了以CPU多核心计算均衡和核心间交互数据量最小为目标的有源配电网优化分网策略;在此基础上建立了元件接口等效模型和子任务协调模型,提出了CPU子任务间多速率并行、子任务内部仿真步长自适应调整的并行仿真方法,达到加速暂态仿真的目的。通过对变电站同一母线的12条出线进行仿真测试,验证了所提并行仿真方法能够满足配电网暂态的仿真需求,在保证仿真精度的同时大幅提高计算速度。

关键词(KeyWords)： 有源配电网;暂态过程;网络分解;自适应变步长;多速率并行仿真
