dc.description.abstractIn this paper an improved control method for hybrid AC/DC microgrids, focusing on interlinking converter control is proposed. The modification of interlinking converter control is based on considering transient fault situations in both ac and dc subgrids for grid connected mode. According to the main role of interlinking converter as a gateway to deal with bidirectional power transfer control and both ac and dc side voltage control, the transients of ac or dc side faults can be transferred through the converter and harms the other subgrid and even worsening the fault situation. Thus, the effect of ac and dc side faults on the performance of interlinking converter and the main parameters of both subgrids are investigated. Then, a supplementary control is proposed to be capable of distinguishing the fault situations. Finally, in order to prevent transient fault transfer and improve the capability of interlinking converter, a downstream fault limiting function has been added to its operation. A hybrid ac/dc microgrid is simulated and simulation results for ac and dc faults are presented to validate the effectiveness and advantages of the proposed control method using PSCAD/EMTDC software. The simulation results demonstrate appropriate performance of interlinking converter on fault bypass and fault current limitations especially in dc subgrid faults.
