Abstract

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
