Voltage unbalancing reduction in a stand-alone ac-dc hybrid microgrid based on floating compensation reference [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2020 A hybrid AC-DC microgrid consists of an AC and a DC subgrid that are connected to each other through an interlinking converter (IC). The main function of an IC under islanded conditions is to transfer power between the two subgrids.
