摘　　要：在“碳达峰、碳中和”战略目标驱动下,电力系统逐渐发展成为高比例新能源并网和高比例电力电子设备接入的新型电力系统,其电源结构、电网形态和运行特征发生了显著变化。电磁暂态仿真由于能够全面、精确刻画电力系统的高频动态特性,已成为掌握新型电力系统运行特性的关键手段。然而,传统串行计算模式下的电磁暂态仿真技术在仿真效率上无法应对新能源大规模并网、交直流复杂耦合的仿真场景,亟需从高效并行算法和硬件加速角度出发,开展并行计算模式下的电磁暂态仿真相关研究。为此,首先概括了新型电力系统对电磁暂态仿真的新需求;其次,介绍了电磁暂态仿真的分网并行算法;再次,介绍了能够进一步提升电磁暂态仿真效率的多速率仿真方法;接着,介绍了基于并行计算设备的并行仿真实现方案;最后,梳理了国内外电磁暂态仿真平台的并行策略,总结指出算法硬件深度融合的仿真平台是未来的发展方向,并对其中的关键技术进行分析和展望。Driven by the strategic goals of“peak carbon emissions”and“carbon neutrality”,power system is transforming into a new power system marked by extensive integration of new energy sources and a significant presence of power elec-tronic devices.This transformation induces significant changes in its power source structure,and operational characteristics.Electromagnetic transient simulation,possessing the capability to comprehensively and precisely depict the high-frequency dynamic traits of the power system,has become a pivotal tool for understanding the operational fea-tures of the new power system.However,electromagnetic transient simulation techniques under the traditional serial computing mode is inadequate in addressing the simulation scenarios involving the large-scale integration of new energy sources and the complex coupling of AC and DC systems.Urgent research is needed to explore efficient parallel algo-rithms and hardware acceleration perspectives for electromagnetic transient simulation in a parallel computing mode.To this end,this paper first outlines the new demands of the new power system for electromagnetic transient simulation.It then introduces parallel algorithms for electromagnetic transient simulation,followed by a presentation of multi-rate sim-ulation methods to further enhance efficiency,and introduces parallel simulation implementation schemes based on parallel computing devices.Finally,it reviews the parallel strategies of electromagnetic transient simulation platforms domestically and internationally,concludes that a simulation platform with deep integration of algorithm and hardware is the future direction,and also provides an analysis and outlook on key technologies involved.
