Abstract

Bidirectional Inter-Allied Converters (BIACs) plays a major role in hybrid ac-dc microgrids (HM) forming as a bridging unit for power exchange between ac and dc subgrids. Overcoming the stress faced by single BIAC multiple converter structure i.e BIAC community came into existence. Considering advantages over two-level converters, multi-level converters sustain its position in today and future applications. Implementing the multi-level converter topology for distributed power management enhances the system efficiency with less amount of harmonic content. This paper presents implementation of Multi Level Bidirectional Inter Allied Converter (MLBIAC) community along with the Localized Distributed Proportional Integral Controller (LDPIC) located at each converter in HM for distributed power management. The localized distribution controller includes PI controller for system stability and which allows exchanging the information in more flexible way. To achieve the global power sharing by implementing MLBIAC in HM, the concepts like balanced power sharing, leading role transition, bidirectional power flow, system stability were analyzed and simulated using MATLAB/Simulink software.
