Software-in-the-Loop (SIL) testing is an approach used for verification and validation in the energy sector. However, there is no comprehensive overview of the application, potential, and challenges of SIL within this sector. Therefore, this paper conducts a thorough scoping review of the existing literature within the scope of SIL and related in-the-loop approaches in the energy sector. A total of 88 full-text articles from four significant databases ACM, IEEE Xplore, Scopus, and Web of Science are analyzed and categorized to map the purpose, methods, architecture, interoperability and protocols, technologies, challenges, and limitations. The results present a grand perspective of in-the-loop across several domains followed by an analysis of SIL in the energy sector. The application domains carry characteristics from complex systems, systems-of-systems, cyber-physical systems, critical systems, real-time systems, and sociotechnical systems. The energy sector and the automotive industry are amongst the most applied domains. Within energy- and electricity systems, hardware-based in-the-loop paradigms are mostly applied for testing low-level signaling, and SIL is used for control strategy testing, optimization, dispatching, and experimentation. The examined SIL architectures have distributed-, real-time, and closed-loop properties, and are constrained by specialized simulation power hardware. Future research should address how to systematically develop SIL testing environments with guiding principles to support application development for the future digitalized energy system.

对能源领域环内范式的范围审查，重点关注软件在环

软件在环 (SIL) 测试是一种用于能源领域验证和确认的方法。然而，尚无关于 SIL 在该领域的应用、潜力和挑战的全面概述。因此，本文对能源领域 SIL 和相关环内方法范围内的现有文献进行了彻底的范围审查。对来自四个重要数据库 ACM、IEEE Xplore、Scopus 和 Web of Science 的总共 88 篇全文文章进行了分析和分类，以映射目的、方法、架构、互操作性和协议、技术、挑战和限制。结果呈现了跨多个领域的在环宏观视角，随后对能源领域的 SIL 进行了分析。应用领域具有复杂系统、系统系统、网络物理系统、关键系统、实时系统和社会技术系统的特征。能源行业和汽车行业是应用最广泛的领域之一。在能源和电力系统中，基于硬件的在环范例主要用于测试低级信令，而SIL用于控制策略测试、优化、调度和实验。所检查的 SIL 架构具有分布式、实时和闭环特性，并受到专用仿真​​电源硬件的限制。未来的研究应解决如何系统地开发 SIL 测试环境和指导原则，以支持未来数字化能源系统的应用程序开发。
