In response to this growing uncertainty, microgrids are gaining attention as a practical way to strengthen energy security and improve grid flexibility. . Unlike traditional coal or gas plants, solar and wind systems rely on inverters and don't provide the same kind of “inertia” that helps stabilize the grid. That makes it harder to maintain balance when conditions change quickly. However, given that they depend on unplanned environmental factors, these systems have an unstable generation. . NLR has been involved in the modeling, development, testing, and deployment of microgrids since 2001. Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms.
