Girding the Grid: Engineers rethink power storage for wind

Watch OSU electrical engineer Ted Brekken explain the need to modify the electrical grid.

As wind turbines and solar arrays sprout up across the landscape, an urgent challenge arises: How to capture all that alternative energy for the electrical grid. Wind velocity and solar intensity vary wildly as weather changes and as seasons shift — fluctuations that are often out of sync with power demand.

With $399,973 in funding from the American Recovery and Reinvestment Act of 2009, OSU engineer Ted Brekken is tackling the problem by investigating scaled-up energy storage systems to even out the variability of wind energy generation. Such systems — which he likens to giant batteries — would “buffer the peaks and valleys in wind farm production,” he says. Wind energy thus would become “more predictable, more forecastable.
