Operating Reserves and Ancillary Services: To maintain reliable power system operations, generation must exactly match electricity demand at all times. There are various categories of operating reserves

www.nrel.govfound that operating reserves were lower for the high solar scenario (25% solar) than the high wind scenario (25% wind) (Lew 2013). ... accommodate changes in variable generation. This type of cycling of fossil-fueled generators can result in an increase in wear-and-tear on the units and a decrease in efficiency, particularly from ...
