Grid Technologies and Systems

NREL develops and evaluates technologies and systems that enable power grids to function more efficiently, integrate more energy resources, and be more resilient and secure under all operating conditions.

NREL research focuses on devices and systems at the transmission and distribution levels. Specific grid technologies that NREL researchers are evaluating include:

• Hybrid energy generation technologies that combine the features of individual technologies for optimized value
• Grid-enhancing technologies (such as dynamic line ratings and power flow controllers) that improve the overall efficiency and use of transmission and distribution systems 
• Power electronic converters (such as inverters and rectifiers)
• Storage technologies (such as batteries, flywheels, and thermal storage)
• Delivery technologies (such as conductors and transformers)
• Consumption technologies (such as electric vehicles; building loads; lighting; and heating, ventilating, and air-conditioning systems).

As networks of devices, integrated systems are physically connected and linked by control systems and markets—such as in microgrid, distribution, and bulk-power systems.
