A new study from the United States Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) used high-performance computing capabilities and innovative visualization tools to model, in unprecedented detail, how the power grid of the eastern United States could operationally accommodate higher levels of wind and solar photovoltaic generation. The analysis considered scenarios of up to 30 percent annual penetration of wind and solar. Whereas previous studies have investigated operations in one-hour intervals, NREL’s Eastern Renewable Generation Integration Study (ERGIS) analyzed a year of operations at 5-minute intervals, the same real-time interval used by grid operators for scheduling resources. “By modeling the power system in depth and detail, NREL has helped reset the conversation about how far we can go operationally with wind and solar in one of the largest power systems in the world,” said the Energy Department’s Charlton Clark, a DOE program manager for the study.
