NREL has been involved in the modeling, development, testing, and deployment of microgrids since 2001. A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode.

A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a college campus, hospital complex, business center or neighborhood. Within microgrids are one or more kinds of distributed energy (solar panels, wind turbines, combined heat and power, generators) that produce its power.
In low-voltage energy storage microgird systems, the quasi-single-stage architecture is a promising alternative to improve the efficiency, which contains a direct power flow path from the battery to the inverter, resulting in reduced power losses by dc/dc converter. However, the unbalanced dc-link voltage of two ports certainly generates asymmetric space …
