中国微电网技术研究及其应用现状

Research on Microgrid and Its Application in China

笔者介绍了中国在微电网研究和应用方面的现状。中国的微电网技术跟随着国外研究的脚步,自2004年左右开始逐渐兴起,目前已经成为智能电网技术中最活跃的分支之一。中国的微电网技术发展受智能电网的深化和能源需求发展的激励,与分布式发电技术的发展紧密联系,存在科研院所主导的微电网技术研究和企业主导的微电网技术应用两个主要方向。目前各省都已经有了微电网技术研究和应用的典型代表。以天津大学、合肥工业大学、西安交通大学、中科院电工所为代表的科研院所建立了自己的微电网实验系统,在微电网技术研究方面处于国内领先地位。而以国家电网、南方电网为代表的企业纷纷建立了自己的微电网示范工程,不断加快微电网技术应用的步伐。笔者针对中国微电网发展的现状,提出了微电网发展所面临的问题和应对办法。

This paper presents the state of the art research and application of microgrid in China,and then introduces the major concerns for the development of microgrid. The research related to microgrid in China arose around 2004,focusing on the connection of distributed energy resources （DERs） to grid and its influence on distribution network,and then followed the microgrid concept of Consortium for Electric Reliability Technology Solutions （CERTS）. However,the microgrid in China has taken a more active path with the development of DER and the encouragement of the development of smart grid and resource and energy needing. Now,nearly every province in China has typical researches and applications of microgrid. Besides,there are already two major patterns in the development of microgrid,the institute-dominating research and the enterprise-dominating application. Research institutions like Tianjin University,HeFei University of Technology,Xi＇an Jiaotong University,Institute of Electrical Engineering （Chinese Academy of Sciences）,etc. ,are leading the research on microgrid. The companies like State Grid Corporation of China （SGCC）,China Southern Power Grid （CSPG）,etc., have accomplished several demonstration projects of microgrid, and give a further boost to its application. At the end of the paper, according to the present situation of the development of microgrid in China,put forward the facing problems and the way to deal with it.
