A microgrid control system (MCS) is the central intelligence layer that manages the complex operations of a localized power grid. This system integrates diverse power sources, such as solar arrays, wind turbines, and battery storage, collectively known as Distributed Energy. . NLR develops and evaluates microgrid controls at multiple time scales. Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms. In a grid connected mode, the objective of microgrid operation is to maximize renewable power and enable participation in behind-the-meter (BTM). . Microgrids are viewed as a vital building block to achieve a modern and future electricity systems.
