摘　　要：微电网是未来智能配用电系统的重要组成部分,对推进节能减排和实现能源可持续发展具有重要意义。相比交流微电网,直流微电网可更高效可靠地接纳风、光等分布式可再生能源发电系统、储能单元、电动汽车及其他直流用电负荷。该文首先对国内外学术界和工业界在直流微电网领域的相关技术和实验系统研究现状进行梳理;然后,从技术角度对直流微电网拓扑结构、优化规划、运行控制、保护及通信等几个方面进行了分析归纳;最后从交直流混合微电网、交直流混合配电网以及能源互联网等方面展望了直流微电网的发展和应用前景。As an important part of the future smart distribution system, microgrid can make a significant contribution to promote energy saving, emission reduction and achieve the sustainable energy development. Compared with AC microgrids, the DC microgrid has been a promising solution for interfacing the solar/wind renewable energy sources based distributed generation systems, energy storage systems, electric vehicles and other DC loads, with less energy conversion stages. So the system can operate with improved energy conversion efficiency, economy and reliability. In this paper, firstly, the latest research and development of technologies and platforms of DC microgrids from industry and academia was summarized. Secondly, the topology structure, optimal planning, operation control, protection and communication technology of DC microgrids were described and analyzed. Finally, the future development and application of DC microgrids were described in AC/DC hybrid microgrids, hybrid distribution systems and energy internets.
