Following a 2006 request for proposals (RFP), Portland, Ore.-headquartered Bonneville Power Administration (BPA) has awarded nearly $2 million in contracts to research and develop ways to help manage the intermittent nature of renewable energy. Four of the project will address wind power.

The first research project, to be conducted by Seattle-headquartered 3Tier Group, will involve wind assessment at 2 km square grid for the entire Pacific Northwest and support the NWPCC Wind Integration Action Plan for regional coordination of large-scale wind development.

In another wind project offered funding by BPA, 3Tier will focus on identifying wind ramp periods 2.5 days ahead using innovative meteorological techniques at three wind plants in the BPA control area.

A third project, to be conducted by North Carolina State and the Department of Energy, will investigate a five-level static synchronous compensator to correct voltage fluctuations and design of energy storage system controls to mitigate wind intermittency.

The fourth wind energy project funded by BPA, to be conducted by Second Wind and Oregon State University, will evaluate the capability of SODAR to accurately measure surface winds from 30 meters to 130 meters. This research represents the first step in the development of a real- time wind ramp forecast system, BPA adds.
