4. 3. Anti-Islanding Protection in Distribution Grids

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jianan Zhang; [2019]
   Keywords : ;

   Abstract : The growing number of distributed generation in the electrical system increasesthe risk of unintentional islanding. Power system islanding is the eventthat a part of the grid is continuously powered by the distributed generation,while it is already electrically separated from the power grid[1]. READ MORE
