The power industry is undergoing a rapid transformation with the adoption of smart grid standards, advanced communication infrastructure, and new technologies for distributed power. MVDC (Medium Voltage Direct Current) technology plays a vital role in promoting efficient energy transmission and reducing greenhouse gas emissions, necessitating a structured architecture for stable management. This paper implements services defined in IEC 61850 and IEC 62541, defining a Virtual Manufacturing Device (VMD) to objectify the DTS (Digital Twin System). The VMD abstracts essential functions for control and monitoring, which are realized in DTS to enhance capabilities. The objectified DTS data facilitates server-client data exchange. Additionally, the proposed DTS-MS communication protocol defines transmitted data in JSON for remote access, providing node functionality for MVDC testing environments. The paper analyzes reference models for Digital Twin, proposes an Ethernet-based DTS architecture using international standards, and verifies the real-time performance improvements of the proposed system through mathematical simulations.
