微电网技术进展及其对实现智能电网的影响

Research Progress of MicroGrids and Its Influence on the Realization of SmartGrids

传统的配电网在接入分布式发电机后,分布式发电设备数量的增加将对原有系统在控制和保护方面产生严重影响。微电网就是针对这一问题提出的一种解决方案。要实现微电网安全稳定运行,控制和保护是其中的两个关键问题。本文首先介绍了微电网的基本概念,然后针对微电网的具体特点,阐述了与微电网相关的控制和保护技术的研究进展。最后,通过对比微电网和智能电网的特点,说明了微电网在实现智能电网中的特殊意义。

As a lot of distribution generation penetrates conventional distribution network,it will affect the control and protection schemes applied in the system.In order to overcome such problems,MicroGrids（MG） are formed.But control and protection are the greatest challenges that prevent the realization of MG.Firstly,the basic concept presents in the paper.Then research progress in control and protection of MG has been described.In the last,through comparing the characters of MG and SmartGrids（SG）,this paper conceals the meaning of MG for the realization of SG.
