中文摘要：

微电网作为坚强智能电网的重要组成部分,能够高效地集成各种分布式能源,提高可再生能源的渗透率,弥补大电网供电集中的缺陷,因此近年来备受关注和发展。由于我国微电网研究起步晚,技术、标准和推广性尚不成熟,仍处于实验和摸索阶段。因此根据现有的文献资料,首先简要说明微电网的定义、分类、用途及结构,然后分析了中国微电网试点项目建设情况及特点,最后结合我国现有微电网特点及科研现状总结了我国微电网的发展趋势。

英文摘要：

As an important component of strong smart grid, micro-grid has attracted much attention and undergone development in certain degree in recent years in China because it can effectively integrate distributed resources, enhance penetration of renewable energy and remedy disadvantages of large centralized power supply. However, its initial development is late in China, and still in stage of experiment and exploration with immature technological level and limited generalization. In this context, starting with background of micro-grid research, conception of micro-grid, its classification, usage and structure are presented briefly in this paper. Construction and features of micro-grid pilot projects in China are analyzed in detail. Finally, development trend of micro-grid is concluded in aspects of features of micro-grid projects and research status.
