According to the Department of Energy, 70% of U.S. transmission lines are nearing the end of their lifecycle. Aging systems increasingly fail to meet modern needs, lacking wildfire and extreme weather resilience, cybersecurity hardening, and distributed generation flexibility. Luckily, grid modernization—and the benefits entailed—are within reach.

The National Renewable Energy Laboratory (NREL) put several microgrid controllers through rigorous hardware-in-the-loop (HIL) testing in its procurement process. See the metrics NREL used to evaluate the controllers’ responses to a variety of system events and conditions—and how the SEL controller performed. https://lnkd.in/gdPgNMcT #RenewableEnergy #Microgrids #RTAC
