微电网的概念最早是由美国提出的[1]。2002年美国

CERTS对微电网概念提出了明确的定义，并且给出了微电

网的基本结构。它主要是通过电力电子装置将发电容量小

于500 kW的分布式电源和储能装置组织在一起，就近向

用户提供电能。灵活智能的电力电子装置是CERTS微电网

的关键所在，正是通过该技术来实现“即插即用”的控制

思想。目前，微电网的应用范围和电压等级正在不断的扩

大，已经由原来兆瓦级以下发展到几十兆瓦的规模，并有

望在更大的农村配电网得到进一步发展。-Microgrid concept was first proposed by the United States [1]. 2002 U.S. CERTS Microgrid concept presented on a clear definition, and gives the basic structure of microgrid. It is mainly through the power electronic device generating capacity of less than 500 kW of distributed power and energy storage devices are grouped together, the nearest to the user to provide power. Flexible and intelligent power electronic devices CERTS Microgrid is the key to it is through the technology to achieve " plug and play"　control thought. Currently, the range of applications and micro-grid voltage level is constantly expanding, has increased from less developed to the megawatt scale of tens of megawatts and is expected to be greater the further development of the rural distribution network.
