摘　　要：随着化石能源的日益枯竭,风电、光伏发电等可再生能源、储能系统、电动汽车等新技术逐渐得到人们的重视。但它们在并网时会产生不可避免的换流损耗,而直流配电网在降低新能源换流成本、提高其能量利用率等方面具有较为明显的优势,且通过对换流器运行指令的合理有效设计,可以实现直流配电网的安全、经济、高效运行。文中首先介绍了直流配电网的特点与优势,并对其系统结构进行了简要说明;然后对直流配电网能量优化管理技术以及基于优化指令的换流接口协调控制技术的最新研究进展进行了综述;最后讨论了仍有待进一步改进和完善的相关研究方向。With the ever-increasing exhaustion of fossil energy,renewable energy like wind power,photovoltaic as well as energy storage system and electric vehicles is gradually gaining peoples attention.However,losses during the conversion are inevitable when new energy sources are connected to the network.By adopting the direct current（DC）distribution technology,the cost of conversion can be appreciably reduced.In addition,DC distribution network safe,economical,and highly efficient operation can be realized by designing the converter commands rationally and effectively.The characteristics and advantages of the distribution network are described first,followed by a brief account of its energy structure.Then the latest progress in two aspects,namely,the energy optimizing management technology and the coordinated control strategy among converters based on energy management optimization commands is summarized.In the end,some directions that have yet to be further improved and perfected are discussed.
