Non-isolated Multi-Port Inverter Topologies for Renewable Energy Applications: A review

Using renewable energy sources (RESs) and energy storage system (ESS) in micro-grids are becoming popular and attracting more researchers to make it safe and efficient with minimum cost. Multi-Port Inverters (MPIs) are used to integrate renewable energy sources and energy storage system with load and utility, to deal with the power operation modes and to provide the maximum power point. Recently, many Multi-Port inverters typologies have been proposed and reported in the literature. This paper provides a review of various non-isolated Multi-Port power topologies used for renewable energies applications. These topologies are compared based on their number and types of DC sources, passive elements, and the control strategy for DC and AC ports. Also, a novel classification of Multi-Port power topologies is presented. This review paper is the first of its kind with the aim of providing information of the complete conversion system for renewable energy sources, also, this work helps the researchers, designers and application engineers to now the trends in this filed.
