“…The optimal location and size of RDGs have been the subject of numerous studies. Researchers have focused on developing methodologies that minimize total power losses while determining optimal locations and sizes [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22] and improve voltage profiles [10], [13], [15], [17], [21]. In [9], the authors proposed an analytical expression to estimate the optimal size of the distributed generator (DG) and presented a methodology to determine their locations.…”
