Operation of hybrid AC-DC microgrid with an interlinking converter

Abstract

The proposed paper presents the analysis of power sharing in a renewable hybrid microgrid. The hybrid microgrid presented here comprises the DC and AC subgrid interconnected by an interlinking converter. Droop control technique is presented in this paper for power flow management among all the sources in two types of subgrids. The coordinated operation of DC sources and AC sources and interlinking converters are investigated. The droop control concept uses an appropriate normalization technique for merging both subgrids. The operation of hybrid ac-dc microgrid with an interlinking converter using droop control technique for power sharing is investigated by simulation in this paper.
