The changing physics of the power system

The National Renewable Energy Laboratory just released this video about the how the stability challenges in the power system change as solar PV, wind, and battery energy storage are widely deployed. While in the video I highlight an event from a 75 MW (peak) island power system, these same challenges (and emerging solutions) face large interconnected power systems too. Looking forward to continuing to remove barriers to the #energytransition!

I am lucky to work with great teams on these topics, including Jin Tan , Shuan Dong , Kenny Gruchalla, Ph.D. , Samantha Molnar , Bin Wang , Jiangkai Peng , Przemys?aw Koralewicz , Brad Rockwell , Cameron Kruse , Li Yu, Ph.D. , Xiaonan Lu , Yilu Liu , Kelsey Horowitz , Mike Simpson , and many more. And of course, thank you to the DOE Solar Office sponsors who enabled this work, including John Seuss, PhD , Bishnu Bhattarai, PhD, SMIEEE , and Guohui Yuan, PhD , among others.

Andy, Thanks for sharing the thought-provoking video. I hope we can generate more of these informative and forward-thinking messages in 2024.

Nice video! How much load was the large synchronous generator carrying when it tripped? What caused the trip? If the generator was carrying 50% of the island load before it tripped, I would expect the remaining generators, grid forming or not, to trip on overload, unless automatic load shedding scheme kicked in.

So the Renewable grid without the plant is relying on one grid forming inverter? Is there a backup in that farm or in another site on the island?
