标题： Design and Implementation of Scalable Communication Interfaces for Reliable and Stable Real-time Co-Simulation of Power Systems

摘要： 仿真实验提供了一种集成方法来建模基于逆变器的资源（IBR）大规模整合到输电和配电电网中。 本文提出了一种可扩展的通信接口设计和实现，以实现具有高IBR渗透率的电力系统的可靠且稳定的实时协同仿真。 通信接口分为两种类型：本地和远程。 在本地场景中，其中子系统在一个单一的局域网（LAN）内连接，低延迟通信促进了电磁暂态（EMT）和相量域模型的无缝集成，从而实现与电力和能源管理算法的有效交互。 对于远程场景，数据交换通过基于互联网的文件共享或VPN启用通信实现。 这两种方法的性能使用OPAL-RT作为实时模拟器进行了评估，展示了可扩展性、有效性以及实时协同仿真应用特有的挑战。 为了缓解由于时间敏感的协同仿真中的数据分辨率不匹配导致的不稳定，提出了一种实时数据外推方法。 这种方法显著增强了稳定性和可靠性，确保了更准确的仿真结果。 实现代码可在GitHub上获取，为研究人员提供了复制和扩展这项工作的工具。 显示英文摘要

摘要： Co-simulation offers an integrated approach for modeling the large-scale integration of inverter-based resources (IBRs) into transmission and distribution grids. This paper presents a scalable communication interface design and implementation to enable reliable and stable real-time co-simulation of power systems with high IBR penetration. The communication interface is categorized into two types: local and remote. In local scenarios, where subsystems are connected within a single local area network (LAN), low-latency communication facilitates the seamless integration of electromagnetic transient (EMT) and phasor-domain models, enabling efficient interactions with power and energy management algorithms. For remote scenarios, data exchange is achieved via internet-based file sharing or VPN-enabled communication. The performance of both methods is evaluated using OPAL-RT as a real-time simulator, demonstrating scalability, effectiveness, and challenges specific to real-time co-simulation applications. To mitigate instability arising from data resolution mismatches in time-sensitive co-simulations, a real-time data extrapolation method is proposed. This approach significantly enhances stability and reliability, ensuring more accurate simulation outcomes. The implementation code is available on GitHub, providing researchers the tools to replicate and expand upon this work.
