摘要(Abstract)：
直流微电网是一种新兴的微电网形式,与交流微电网相比,具有线路损耗低、电能质量高、重构灵活等优势,可以更充分发挥分布式电源以及微电网的价值和效益。为此,根据现有文献资料,从电压等级、母线结构、网络拓扑、接地方式等方面对直流微电网的供电模式进行了详细阐述与探讨,可为深入开展直流微电网的相关研究提供参考。
As a newly-emerged microgrid,DC microgrid,in contrast with AC microgrid,is advantageous in low line loss,high power quality and flexible in reconstruction,which enable better exertion of value and benefit of distributed distribution and microgrid.Therefore,the paper,on the basis of existing documents and files,expounds and discusses power supply mode for DC microgrid in terms of voltage class,bus configuration,network topology,providing reference for relevant further study on DC microgrid.
