An overview of real time hardware-in-the-loop capabilities in digital simulation for electric microgrids

This paper explores and presents the capabilities of real time hardware-in-the-loop (RT-HIL) digital simulation for electric microgrids. RT-HIL is used by academia and industry for the simulation and testing of power systems at both the component and system levels. A literature survey is presented to identify existing real time simulation systems and some relevant applications. Simulations using RT-HIL involve modeling the interface between the components and systems in greater detail for increased understanding of interface issues. This is aimed at de-risking and hastening the penetration of new technologies such as microgrids.
