Abstract

The rapid deployment of renewable energy resources has led to the widespread use of power electronics in modern power systems. As these systems transition from being dominated by large synchronous machines to increasingly incorporating inverter-based resources (IBRs), traditional transmission simulation tools that do not model the dynamics of distribution networks with a large amount of Distributed Energy Resources (DERs) are becoming inadequate. Addressing this challenge, this paper introduces a scalable phasor-domain transmission and distribution (T&D) co-simulation framework that accurately captures system dynamic behaviors under various configurations of grid-forming and grid-following inverters based on open-source software. The main focus is on the validation of this co-simulation framework against the PSCAD Electromagnetic Transient (EMT) analysis tool for a three-phase line-to-ground fault scenario. The validation results clearly demonstrate the framework’s high fidelity and a computational time speed-up of 60 to 100 times, marking a pioneering validation effort between phasor-domain and EMT simulation in T&D co-simulation research.

根据电磁瞬态仿真验证相量域输配电协同仿真⁎

可再生能源的快速部署促使电力电子技术在现代电力系统中得到广泛应用。随着这些系统从以大型同步机为主过渡到越来越多地采用基于逆变器的资源 (IBR)，传统的输电仿真工具已不足以模拟具有大量分布式能源资源 (DER) 的配电网络的动态。为了应对这一挑战，本文介绍了一种可扩展的相量域输配电（T&D）协同仿真框架，该框架基于开源软件，能够准确捕捉各种成网和随网逆变器配置下的系统动态行为。主要重点是针对三相线对地故障场景，利用 PSCAD 电磁暂态 (EMT) 分析工具对该协同仿真框架进行验证。验证结果清楚地表明了该框架的高保真性和 60-100 倍的计算速度，标志着在 T&D 协同仿真研究中相量域仿真和 EMT 仿真之间的开创性验证工作。
