Hardware-in-Loop Simulation of Real-Time Cyber-Physical System for DC Microgrids

摘要

DC microgrids have the advantages of high efficiency, economy, and safety, which can reliably accommodate distributed renewable energy power generation systems, energy storage devices, and DC loads. In order to improve the test accuracy and authenticity of DC microgrids control, a hardware-in-loop (HIL) simulation platform of real-time cyber-physical system (CPS) for DC microgrids based on RT-LAB and LabVIEW is established in this paper. HIL simulation and multiple communication methods are adopted to realize real-time data interaction, and further increase the credibility of the entire model. Moreover, real-time host computer system is designed to realize the data monitoring and visual control. Finally, a case study is illustrated to verify the effectiveness of the proposed simulation platform.
