SoC-based Digital Twin of Power System Simulation

Modern power system because of its high voltage, high power characteristics, makes the hardware experiment with certain safety risk and grid security risks. As a more complex simulation method, digital twins are more extensive in time scale compared with the traditional power system simulation, and more frequent in data interaction with the real system. Digital twins can be applied in power systems in a variety of ways. But at present, the application of digital twin still stays on the application of the whole product life cycle. This paper proposes a new real-time interactive power system simulation architecture based on the digital twin, and set up an electric power system based on SoC platform of digital twin, PL part has set up a twin body for the electric power system, the PS part compare the difference between the twin body and the actual body and then modify the twin body. It also provides the control part which is consistent with the hardware control logic. The platform is lightweight, economical, heterogeneous and compatible with a variety of computing tasks, rich interfaces and strong expansibility. This paper provides a framework for the application of digital twins in power system and provides the platform with rich application value.
