CONTROLLABLE GRID INTERFACE FOR MICROGRIDS

A microgrid connector controller (MGC) for transferring power between a power grid and a microgrid via an AC link. The MCG includes a pair of bidirectional AC/DC converters coupled to a common DC link and each having an AC line. One converter closer to the microgrid is configured to regulate frequency of AC voltage of its AC line to a predetermined frequency. The AC link includes the AC lines coupled in series with a terminal the microgrid, and a current divider coupled to a terminal of the power grid. The current divider is configured to set the first converter's current level lower than the second converter's current level.
