Abstract
Required functions of a microgrid become divers because there are many possible configurations that depend on the location. In order to effectively implement the microgrid system, which consists of a microgrid controller and components with distributed energy resources (DERs), thorough tests should be run to validate controller operation for possible operating conditions. Power-hardware-in-the-loop (PHIL) simulation is a validation method that allows different configurations and yields reliable results. However, PHIL configuration for testing the microgrid controller that can evaluate the communication between a microgrid controller and components as well as the power interaction among microgrid components has not been discussed. Additionally, the difference of the power rating of microgrid components between the deployment site and the test lab needs to be adjusted. In this paper, we configured the PHIL environment, which integrates various equipment in the laboratory with a digital real-time simulation (DRTS), to address these two issues of microgrid controller testing. The test in the configured PHIL environment validated two main functions of the microgrid controller, which supports the diesel generator set operations by controlling the DER, regarding single function and simultaneously activated multiple functions.

Summary
Electricity is still not a granted service for almost a billion people around the globe, mostly in. Since the control system parts of these labs are built by the flexible modeling tools, it is supposed that they have advantages in the stage of developing microgrid control algorithms They still have potential to improve the flexibility in terms of power system configurations by integrating with the digital real-time simulation (DRTS) [13]. From the perspective of testing the microgrid controller, which includes various functions and controls DERs that may interfere with each other, the communication between the controller and the components of the microgrid as well as the power interaction among them needs to be evaluated. Can evaluate the communication between the microgrid controller and the components as well as the power interaction among them, i.e., DG set, PV, BESS, and load; appropriately scales the power rating between physical and simulated devices under test (DUT).
