Microgrids are an emerging technology that offers many benefits compared with traditional power grids, including increased reliability, reduced energy costs, improved energy security, environmental benefits, and increased flexibility. This is particularly important in areas with unstable or unreliable power grids, where power outages are common. Increased Energy. A Microgrid is a group of energy sources located in the same local area that is in turn connected into the national grid while also being able to disconnect from it and operate independently, for example in the event of an electricity outage. Microgrids usually consist of distributed generation. Authorized by Section 40101(d) of the Bipartisan Infrastructure Law (BIL), the Grid Resilience State and Tribal Formula Grants program is designed to strengthen and modernize America's power grid against wildfires, extreme weather, and other natural disasters that are exacerbated by the climate. Among microgrid benefits, electric reliability has gotten the most attention since 2012 when Superstorm Sandy knocked out power to about 8 million electric customers in 15 states and the District of Columbia. Some outages lasted two weeks or more. However, several challenges are associated with microgrid. There is an emerging focus on microgrids as a means to achieve more electric efficiency and less dependence on conventional power grids. These small-scale systems provide an alternative way to create and distribute power (generate as well as distribute locally enabling better control and.
