The main protection challenges in the microgrid are the bi-directional power flow, protection blinding, sympathetic tripping, change in short-circuit level due to different modes of operation, and limited fault current contribution by converter-interfaced sources. . This paper presents a fault simulation on DC microgrid based on direct current was designed using solar PV, battery and fuel cell as a source in MATLAB/Simulink. The power produced by different sources is combined on the same DC bus and given to a DC load. The system takes some precautions against. . rks equipped with power generating sources. The can operate in ted short-circuit. . During grid-tied mode, the bulk grid provides significant short- circuit, while during islanded operation the short-circuit magnitude is small due to inverter-based resources limiting their current output close to nominal ratings. The framework avoids potential risk. . Due to inherent advantages of DC system over AC system such as compatibility with renewable energy sources, storage devices and modern loads, Direct Current Microgrid (DCMG) has been one of the key research areas from last few years.

Both AC and DC currents are used across the energy distribution network. AC is typically used for microgrids and long-distance transmission, whereas DC powers everyday electronics. In fact, we are now witnessing a proliferation of DC equipment associated with renewable energy sources. . DC microgrids can benefit industry and communities, but don't overlook the drawbacks. Microgrids are. . A growing fraction of the combined residential and commercial power load in the US—between 60 and 75 percent—uses DC, driven by the adoption of electric vehicles and HVAC equipment with DC motors. Harry as been a DC entrepreneur since 1988.
