“…On the other hand, the general consensus of the classification of the installed power of the hydropower plants was almost achieved according to the name/title of the installed power of the plants as large, medium, small, mini, micro and pico -159-Journal of Industrial Engineering and Management -http://dx.doi.org/10.3926/jiem.1142 hydropower plants. Some academics worked on the classification of hydropower plants by the installed power or capacity (P) (see Anderson, Doig, Khennas & Rees, 1999;Castaldi, Chastain, Windram & Ziatyk, 2003;Mishra, Singal & Khatod, 2012;Paish, 2002;Voros, Kiranoudis & Maroulis, 1999). The simple clustering algorithm in this model was built up according to the Algorithm 1 on Figure 1 (0 to 1, 1 to 10, 10 to 100, and 100 to 1.000 in MW).…”
