Power management enhancement and smoothing DC voltage using integrated BESS and SMES in Off-grid hybrid AC/DC microgrid based on ILCs [PDF]

Scientific Reports
The 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.
