In (Anam et al., 2018), AC Microgrid and DC Microgrid are compared for efficiency by utilizing solar wind hybrid renewable energy systems. Two systems are simulated, one for AC System and the other for DC system, which is basically the extension of the AC System.
The AC microgrid features two load terminals, a purely DC load terminal comprising mobile, fan, and personal computer, supplied by the AC bus through a rectifier. An electric vehicle charger, considered a DC load in the AC microgrid, is connected through a rectifier.
DC microgrids centralize AC-to-DC rectification, resulting in a reduced number of power-conversion stages and a shared DC bus. Centralization reduces conversion losses and improves overall system efficiency. Motor recuperation systems feed brake energy directly into the DC link, optimizing load sharing and energy distribution.
Connecting the DC microgrid to the AC grid requires a bidirectional power supply. This supply handles AC-to-DC conversion with a high power factor and must be able to perform DC-to-AC conversion as an inverter. Because of the power levels, efficiency as well as thermal management are of top concern.
In order to reduce the economic costs, enhance the efficiency, and improve the structural stability of microgrids, this paper proposes a novel AC/DC hybrid microgrid structure.
