DC microgrid has many technical advantages over AC microgrid, these include easy integration of renewable energy resources, direct connection between the consumer loads and DC bus voltage, more simply mitigated harmonics, and no frequency as well as reactive power control problem.
It was verified that typical AC loads can be directly used in DC microgrids, avoiding adapters and changes in the equipment. This also brings important cost savings for this transition. Under this context, the possible DC microgrid voltage level to allow the direct use of this equipment was also analyzed.
A DC microgrid is a distribution system comprising DC loads, energy storage elements, and DG resources which are generally renewable and have DC output voltage. From: Renewable and Sustainable Energy Reviews , 2016.
Why DC microgrids? • Many renewable sources generate DC, e.g.: photovoltaic, wind, fuel cells • Fewer conversions - increase conversion efficiency – DC-to-AC inversion 85%; AC-to-DC rectifying: 90%; DC-to-DC conversion: 95% • Simpler power-electronic interfaces, fewer points of failure • Easily stored in batteries

6 FAQs about [What are the DC loads in microgrids ]
Why do we need DC microgrids?
Abstract: In recent years, due to the wide utilization of direct current (DC) power sources, such as solar photovoltaic (PV), fuel cells, different DC loads, high-level integration of different energy storage systems such as batteries, supercapacitors, DC microgrids have been gaining more importance.
Can AC loads be used in DC microgrids?
In addition, the change in classical loads to DC loads is also another aspect that will contribute to this change. Aspects related to the adaptation of AC loads to DC microgrids were focused on. It was verified that typical AC loads can be directly used in DC microgrids, avoiding adapters and changes in the equipment.
What are the problems with a dc microgrid?
In the DC microgrids system, two types of problems are major. The first one is a constant power load issue, and the second one is a pulsed power load.
What is the operation principle of dc microgrid?
The operation principle of DC microgrid is similar to AC microgrid. Compared with AC microgrid, DC microgrid is a good solution to reduce the power conversion losses because it only needs once power conversion to connect DC bus. Therefore, DC microgrid has higher system efficiency, lower cost and system size.
Do DC microgrids have a wide range operation scenario?
Many loads in DC MGs are tightly controlled by power electronics. These loads often behave as constant power loads (CPLs) and present negative incremental impedance resulting in degrading stability margins. Hence, new control strategies need to be investigated in order to achieve a wide range operation scenario in DC microgrids.
What are the different types of dc microgrid?
In the distribution system, the DC microgrid can be classified into three types: monopolar, bipolar, and homopolar configurations . Power loss reduction, voltage drop reduction, and increase in electric lines capacity are the advantages of DC distribution system.
