A review of the research on microgrid protection development
摘要
Abstract
Microgrid protection is one of the crucial problems to be solved during the rapid development of microgrid. Since microgrid has many distributed generations connected and is capable of operating in both grid-connected and islanded mode, no obvious features of its fault current can be observed which makes the traditional protection strategy in distributed grid refuse or mistake to respond to the fault. Researchers around the globe have engaged wide studies on this subject. This paper summaries and analyzes various study results in the microgrid protection area. Firstly, the technical challenges in microgrid protection are summed up. And then the existing protection techniques on microgrid are sorted into seven categories, which are differential protection, overcurrent protection, adaptive protection, voltage based protection, intelligent algorithm based protection and fault current compensation method. The benefits and drawbacks of each techniques are presented and discussed. Finally, the possible future trends of microgrid protection are concluded which would provide reference to the following studies in this field.关键词
