Abstract

Abstract: In order to coordinate energy, load and storage in DC micro-grid system and make efficient utilization of new energy, a multi-port converter for DC micro-grid hybrid energy storage is proposed. According to the composition rule of multi-port converter, by inserting the Buck-boost converter and bidirectional Buck-boost converter into the bootstrap converter of Luo-converter, the DC converter topology which can be used for complementation of wind-photovoltaic storage is produced. Two-way transmission of energy is realized. The analysis of all kinds of working conditions shows that each port of the converter is able to work independently and cooperatively. Different work conditions have been simulated in Matlab to validate the feasibility.
