现代电网的成功运行高度依赖于一个可靠、高效的底层通信网络。研究人员和公用事业公司已经开始探索应用新兴的软件定义网络（SDN）技术来提高智能电网的效率和弹性的机遇和挑战。这种趋势需要一个基于仿真的平台，为评估网络应用设计提供足够的灵活性和可控性，并促进从内部研究想法到实际生产的过渡。在本文中，我们提出了DSSnet，一个混合测试平台，结合了配电系统模拟器和SDN模拟器，以支持高保真分析通信网络应用及其对电力系统的影响。我们的贡献在于设计了一个虚拟时间系统，对仿真系统的执行具有严格的可控性，即，在感知到自己的虚拟时钟时暂停和恢复任何指定的容器进程，开销很小，扩展到500个仿真主机，平均开销为70毫秒；还在于基于虚拟时间的两个子系统的高效同步。我们评估了DSSnet的系统性能，并通过评估负载转移算法的案例研究来证明其可用性。
The successful operations of modern power grids are highly dependent on a reliable and efficient underlying communication network. Researchers and utilities have started to explore the opportunities and challenges of applying the emerging software-defined networking (SDN) technology to enhance efficiency and resilience of the Smart Grid. This trend calls for a simulation-based platform that provides sufficient flexibility and controllability for evaluating network application designs, and facilitating the transitions from in-house research ideas to real productions. In this paper, we present DSSnet, a hybrid testing platform that combines a power distribution system simulator with an SDN emulator to support high fidelity analysis of communication network applications and their impacts on the power systems. Our contributions lay in the design of a virtual time system with the tight controllability on the execution of the emulation system, i.e., pausing and resuming any specified container processes in the perception of their own virtual clocks, with little overhead scaling to 500 emulated hosts with an average of 70 ms overhead; and also lay in the efficient synchronization of the two sub-systems based on the virtual time. We evaluate the system performance of DSSnet, and also demonstrate the usability through a case study by evaluating a load shifting algorithm.
