Power Systems Simulation and Analysis: A Review on Current Applications and Future Trends in DRTS of Grid-Connected Technologies

Abstract

Real-time simulation is a well-established approach employed across various domains, predominantly through Hardware-In-the-Loop (HIL) simulation. HIL technology enables more realistic simulations of complex systems, usually achieved by a closed-loop scheme between the hardware under test and the real-time simulator. In the field of power systems, it is also progressively deployed not only for academic aspects but also for industrial applications. A HIL model takes advantage of such merits as alleviating the risk of damage to the major real objects and reducing the cost as well as tedious efforts during the test. Besides, the evolution and increasing computing power of real-time simulators promise the capability to reach more accurate models that closely represent reality. Accordingly, this manuscript aims to investigate some applications of HIL grid-integrated technologies in transmission systems and discuss some future trends and scopes correlating to this context.
