A new study from the National Renewable Energy Laboratory (NREL) focuses on "the use of wind power to support power system reliability by providing active power control (APC) at fast time scales," according to North American Windpower. The report, "Active Power Controls from Wind Power: Bridging the Gaps," developed proposals for new ancillary services designs in U.S. wholesale electricity markets, studied how wind power affects system frequency in the western U.S. with and without active power control, and tested the use of active power control at the NREL's National Wind Technology Center (NWTC) to better understand the performance and structural impacts on wind turbines when providing active power control to the electric system, the article said.
