Intermittency or Uncertainty? Impacts of Renewable Energy in Electricity Markets

Weber, Paige; Woerman, Matt - 2022

Renewable energy resources possess unique characteristics—intermittency and uncertainty— that pose challenges to electricity grid operations. We study these characteristics and find that uncertainty, represented by wind forecast error, has larger grid impacts than intermittency, or hourly...

Designing an index for assessing wind energy potential

Ritter, Matthias; Shen, Zhiwei; López Cabrera, Brenda; … - 2014

To meet the increasing global demand for renewable energy such as wind energy, more and more new wind parks are installed worldwide. Finding a suitable location, however, requires a detailed and often costly analysis of the local wind conditions. Plain average wind speed maps cannot provide a...
