      Khawaja, Hassan Abbas; Xue, Hui; Eidesen, Hans-Kristian; Andleeb, Zahra; Moatamedi, Mojtaba (Chapter; Bokkapittel, 2024)
      Wind power is an excellent source of renewable energy in areas with sufficient wind resources. Usually, the best locations for wind turbines are on the tops of hills and ridges, where there are lower temperatures [1]. Cold temperatures are responsible for novel challenges [2, 3]. Due to cold climatic conditions, turbine blades are subjected to icing [4]. A number of methods have been proposed and ...
