From smartgridnews.com: Integrating intermittent renewable energy sources like wind into the electric grid has been one of the big challenges facing the smart grid initiative. Now, scientists at DOE’s Pacific Northwest National Laboratory (PNNL) say they have what could be a workaround: plug-in EVs.
“Electric vehicles, coupled with grid-friendly charging, offers a great opportunity, right now, to help electric companies integrate additional wind power into our electric system,” said Michael Kintner-Meyer, a PNNL staff scientist and co-author of the report Using Electric Vehicles to Meet Balancing Requirements Associated with Wind Power.
While growing in popularity, wind power is notoriously unpredictable – it’s not always there when you need it – and on windy days, grid operators struggle with ways to use excess energy or store it. And grid-scale storage is at this point pretty limited in the U.S. . . .
