Sandia has a comprehensive power electronics and controls R&D program focusing on improving performance, efficiency, and reliability of next generation inverters and converters. These capabilities extend to expertise in wide bandgap device physics and fabrication and to the development of novel controls for distributed energy resources aggregation into microgrids or virtual power plants.
Sandia works with industry and utilities to validate and demonstrate new smart grid technologies using laboratory experiments and real-world demonstrations. Sandia applies automated testing platforms to evaluate cybersecurity, interoperability, grid compatibility, controls performance, reliability, and safety of renewable energy and distributed energy resources devices and systems. These activities involve control and power hardware-in-the-loop (c/p-HIL) capabilities. Some examples are Sandia’s SCEPTRE Emulytics, combining controls, cybersecurity, communications, and power systems domains; and the System Validation Platform (SVP), a c-HIL which accelerates the development, certification, and standardization of distributed energy resources technologies through rapid and fully automated laboratory evaluation. Sandia also conducts full-scale demonstrations involving customer and utility assets.
