GE: Wind power can improve grids resiliency

GE’s Energy Consulting business (NYSE: GE) released a study on wind power and grid resiliency. The study, sponsored by the U.S. National Renewable Energy Laboratory, focused on the country’s Eastern Interconnection—and determined that when equipped with the appropriate plant equipment, wind applications can significantly enhance grid resiliency. The study also accounted for how U.S. electrical systems would respond to a large-scale interruption, such as multiple power plants tripping offline.

The conclusions of the study found that wind, which has the ability to respond more quickly, can be more effective compared to thermal generation when controlling grid frequency. The study modeled an aggressive scenario where there was an instantaneous penetration of 25 percent wind generation.

“While GE’s study considered the impact of wind power on the Eastern Interconnection of the U.S., the lessons we’ve learned can be applied in Europe and around the globe,” said Nicholas Miller, lead author of the study and senior technical director for GE’s Energy Consulting business. “The conclusions demonstrate that wind power can be more effective in maintaining frequency than thermal generation when wind farms are equipped with grid friendly controls. These findings should show that the future of wind energy is bright and it will continue to play a larger role in the power we consume.”
