摘要
简要介绍了直流微电网的特点,总结了国内外微电网的研究现状。对目前分布式电源建模分析较多地考虑自身特性,而未能从直流微电网角度考虑其与配电系统的相互影响;孤岛划分策略以及负荷建模的研究无法适用于直流微电网的特性和运行机理等现有研究工作的局限性进行了概括。在此基础上,提出含直流微电网的新型配电系统研究中亟需研究的几个问题。最后,结合中国的电力发展现状,对直流微电网在中国的发展潜力进行了探讨。
The features of DC micro-grid were described and the new research progress of micro-grid was summarized.Limitations of current researches summarized,such as the power distribution generation(DG) modeling without the interactions between DC micro-grid and power distribution system;the islanding strategy and the load modeling which impede the application to micro-grid.Some research topics were proposed for the research of power distribution system with DC micro-grid.Finally,based on the status of power systems in China,the developing potentials and the possible applications of DC micro-grid in China were discussed.
