This paper presents an implementation of a relay-hardware-in-the-loop testbed to test a previously proposed protection scheme of a real-world industry-grade microgrid. While these tools have broad applications in power system research, this review specifically focuses on their utilization in. . Effective testing of relays ensures adequate grid protection which maximises grid stability and reduces downtime preventing costly equipment damage and lost revenue, safeguarding the power grid's integrity. In this ap-proach, the microgrid virtual model interacts with the physical relay in real-time.
