Advanced technique in micro grid protection for various fault by using numerical relay

Abstract

Microgrid is a part of Power System where energy is generated from renewable source and supplied to cus-tomer directly or indirectly. As traditional sources are going to vanish day by day demand of renewable sources goes on increasing. Trading renewable energy route can make India on the pathway to energy independent, low carbon emission, and build foundation for new generation with sustainable future. More research and implementation of microgrid will be conducted to improve micro grid tech-nology. Among different aspects, most challenging task with renewable is protection. Because We cannot predict behavior of nature as it is uncontrollable for human kind. India is having plenty of renewable available as natural re-sources but challenge is to use it in optimized way. Hence protection of micro grid is key issues. This paper discuss technical challenges in protection of microgrid and sug-gested some solutions which help power system to use non-traditional sources in efficient way.
