20 Summary CONCLUSIONS Pulsed load (EMRG) Integration was successful Hybrid DC protection approach combining converter FCL and differential protection was illustrated in numerical simulation. PHIL simulation with the Opal-RT MRTS platform was introduced to emulate a variety of sources and power converters to argument the capability of the subscale ADM system. FUTURE WORK Conduct hardware test for the dc fault protection on subscale ADM configuration. Demonstrate multiple charge and discharge cycles of the pulsed load and integrate hybrid energy storage in the dc microgrid
