Evaluating new technological developments for energy systems is becoming more and more complex. The overall application environment is a continuously growing and interconnected cyber-physical system so that analytical assessment is practically impossible to realize. Consequently, new solutions must be evaluated in simulation studies. Due to the interdisciplinarity of the simulation scenarios, various heterogeneous tools must be connected. This approach is known as co-simulation. During the last years, different approaches have been developed or adapted for applications in energy systems. In this paper, two co-simulation approaches are compared that follow generic, versatile concepts. The tool mosaik, which has been explicitly developed for the purpose of co-simulation in complex energy systems, is compared to the High Level Architecture (HLA), which possesses a domain-independent scope but is often employed in the energy domain. The comparison is twofold, considering the tools’ conceptual architectures as well as results from the simulation of representative test cases. It suggests that mosaik may be the better choice for entry-level, prototypical co-simulation while HLA is more suited for complex and extensive studies.

与MOSAIK和HLA的智能电网协同仿真：对比研究

评估能源系统的新技术发展变得越来越复杂。整个应用程序环境是一个不断发展且相互联系的网络物理系统，因此实际上不可能实现分析评估。因此，必须在仿真研究中评估新的解决方案。由于模拟方案的跨学科性，因此必须连接各种异构工具。这种方法称为协同仿真。在过去的几年中，已经开发出或适用于能源系统的不同方法。在本文中，比较了两种遵循通用通用概念的协同仿真方法。工具mosaik专门为复杂能源系统中的协同仿真目的而明确开发的软件，与具有领域无关范围但经常在能源领域采用的高级架构（HLA）进行了比较。考虑到工具的概念架构以及代表性测试用例的仿真结果，比较是双重的。这表明mosaik可能是入门级，原型协同仿真的更好选择，而HLA更适合于复杂而广泛的研究。
