A Review of Architecture and Control Strategies of Hybrid AC/DC Microgrid

Abstract

This paper reviews architecture of hybrid AC/DC microgrid and several controlling strategies for hybrid AC/DC microgrid. Interconnected group of networks of loads, energy storage system and distributed energy sources defines a microgrid. To avoid multiple conversion that occurs in individual AC as well as DC grid in the microgrid system, hybrid microgrid is a solution for such issues. Balancing of power between both the microgrids is done with an Interlinking converter. It will balance power by transfer of power through one microgrid to another. This paper summarizes various controlling methods from the several aspects and existing issues in every method presented here.
