微电网技术现状及未来发展分析

摘要

微电网技术是解决分布式发电不可控及随机波动性接入电网的有效方式。文章重点介绍了微电网的提出及发展历程，归纳了微电网的类型，并将发展中交直流混合微电网归结为“交流母线占优”和“直流母线占优”两种类型；分析了国内外微电网的重点工程案例及技术现状，提出了微电网的重点发展方向及趋势。%The micro-grid technology is an effective way to solve the uncontrolled and stochastic volatility distributed generation connected to the grid,this paper highlight the origin and development history of microgird,classify them based on applications scenarios,and suggest that classifying the AC/DC micorgird to “Ac bus domain”and “Dc bus domain”;by the time ,this paper highlight the important microgrid project at home and abroad and the technical status of microgird,and propose the key development orientation and development tendency of microgird.
