Microgrid Field Trials in Sweden: Expanding the Electric Infrastructure in the Village of Simris

Microgrids (MGs) are electricity-distribution systems containing loads and distributed energy resources (DERs) that can be operated in a controlled, coordinated way, either while connected to the main power network and/or while islanded. MGs have been around for decades in the energy system. They can be commonly found in critical infrastructure building complexes such as military bases, hospitals, and data centers. With the challenges of the new energy world, network operators are starting to look into the technological solutions used in MGs (e.g., MG controllers) as an alternative to their conventional network technologies.
