A quick review to understand micro grid system: system architectures, modes and challenges

Abstract

This paper highlighting the main issues in the new era of distributed generation closed to the distribution network or popularly known as Micro Grid (MG) system, in the electrical power system network. A MG is particularly a section of the large power distribution system that comprises distributed or co-generation, energy storage system and loads. In this paper, review on the system architecture, operational modes and also the control challenges on the demand response in MG system is demonstrated. The gathered information is compressed and then written in brief to be used as a quick guide for the new researchers or newcomers in this field. All important elements in the MG will be explained in brief as well as comparing the worthy outcomes and the potential fields of research in particular in terms of energy flow control that would enhance practical use of MG system and its elements.
