摘要/Abstract

摘要：

为解决大规模交/直流电力系统多时间尺度动态复杂，现有混合仿真在多速率协调时存在接口延迟和频率损失，影响精度问题，提出了一种基于多速率异步协调的移频分析混合仿真算法。在多区域戴维南等值(multi-area Thevenin equivalence，MATE)框架下，引入基于内插的异步协调机制，有效消除了接口延时；通过扩展移频分析(shifted frequency analysis，SFA)理论并设计通用接口模型，实现不同速率、不同类型模型分区间的无损数据交互。在交/直流测试系统上的算例表明：所提方法即使在分区步长比较大时，仍能准确仿真高频动态，兼顾了仿真精度与效率。

Abstract:

Large-scale AC/DC power systems exhibit complex dynamics across multiple time scales, and existing hybrid simulations suffer from interface delays and frequency losses during multi-rate coordination, compromising accuracy. To address this issue, a multi-rate asynchronous coordination method was proposed to construct hybrid simulations using shifted frequency analysis (SFA). Within the multi-area Thevenin equivalence (MATE) framework, the algorithm introduced an interpolation-based asynchronous coordination mechanism, effectively eliminating interface delays; by extending SFA theory and designing a universal interface model, it achieved lossless data exchange between partitions with different rates and model types. Case studies on an AC/DC test system demonstrate that the proposed method, even with large time step ratios between partitions, can still accurately simulate high-frequency dynamics, balancing simulation accuracy and efficiency.

Key words: hybrid simulation, multi-rate simulation, asynchronous coordination, shifted frequency analysis, AC/DC power system
