Design of Deterministic Transmission Framework for Distributed Power System Based on Digital Twin

Energy networking and intelligence have jointly promoted the development of distributed power systems. As humankind's largest and most complex industrial system so far, the power system has higher requirements for the real-time performance of data transmission. The distributed power system based on digital twin technology realizes real-time monitoring and accurate system load forecasting through intelligent perception, real-time transmission, virtual-real interaction, artificial intelligence, and other technologies. Based on the design of digital twin technology, this paper proposes a TSN configuration method for information interaction on the virtual and real sides of the distributed power generation system. This method modifies the transmission standard of the data link layer in the original IEC61850 standard, which can effectively reduce the response time in the communication process and improve the certainty of control information flow transmission.
