Microgrid architecture for distributed generation: Issues and challenges.

A new power framework is evolving that combines green resources and distribution network. It is theologically based on major themes such as widespread adoption of distributed energy technology, future fossil fuel shortages, liberalization of the electrical service industry, and the customary focus on the environmental impact of traditional electrical power generation methods. These issues are changing the way people think about traditional power generation around the world, and they are posing new challenges to the generation and distribution systems. Numerous technological obstacles await the practical deployment of microgrid. One of the most difficult tasks in a microgrid architecture is devising a compatible protection mechanism. Numerous surveys have been published on microgrid control techniques; moreover, a systematic evaluation of stratified control methods based on a variety of microgrid architectures is rarely acknowledged. The primary, secondary, and tertiary control layers all contribute to the microgrids control hierarchy. This paper provides a summary of the technical issues and potential solutions associated with microgrid, as well as to discuss some of the technical discussions surrounding the bifurcations of the same. This article compares AC, DC, and AC-DC hybrid microgrid. [ABSTRACT FROM AUTHOR]
