This article presents the inclusive DC-link voltage control and protection scheme for the DC-link of the microgrid. The proposed inclusive scheme is proposed to control the DC-link voltage during load-switching or AC-side faults scenarios, and protect the DC-link when short-circuit fault emerges at DC-link. To examine the proposed inclusive scheme, the microgrid test system is created according to the IEEE-1547 standard in PSCAD/EMTDC based software system. Then the designed microgrid is examined under various fault scenarios to confirm the performance of the developed scheme. Results show that the presented control and protection scheme can maintain the DC-link voltage under faults on the AC or DC sides in grid-connected and islanding modes of operation. The proposed scheme has the ability to ensure the voltage regulation and protection of the DC-link of the microgrid under different operating conditions and faults.
