Abstract

Microgrid refers to a localized group of electricity sources and loads that operates connected to the electric grid or grid-independently in island mode. Microgrids are used in powering communities and critical infrastructure such as datacenters to ensure continuous power during grid outage or disruption. It can include various energy sources such as solar panels, wind turbines, generators, fuel cells and batteries. Microgrids enhance the reliability and resilience of power supply, reduce transmission losses and support integration of renewable and clean energy. The reliability of a microgrid is to provide continuous and stable power supply. In this article we will discuss the resilience of microgrids to tolerate various failures, faults. Key aspects will involve looking at individual component reliability, system architecture, redundancy and implementation of control strategies to ensure uninterrupted power supply for critical load.
