Optimal Design of Hybrid AC/DC Microgrids [PDF]
, 2017 DC loads (such as computers, data centres, electric vehicle chargers, and LED lamps) and dc distributed energy resources (such as fuel cells, solar photovoltaics, and energy storages) are rapidly growing in electric power systems, so dc systems are being introduced as emerging practical investment solutions compared to traditional ac options.

Power management enhancement and smoothing DC voltage using integrated BESS and SMES in Off-grid hybrid AC/DC microgrid based on ILCs [PDF]
Scientific ReportsThe random and variable generation of wind and solar energies, particularly in DC microgrids, leads to undesirable fluctuations in the DC link voltage, consequently decreasing the power quality on the DC side.

An experimental case on dual mode coupling energy management strategy for islanded AC/DC hybrid microgrid [PDF]
Scientific ReportsThe limited adjustable margin of the islanded AC/DC hybrid microgrid makes it difficult to both balance economic and stability. Therefore, an energy management strategy that can effectively harmonize economic and stability is highly desirable. In view of
