This pa.er va.ida.es the optim.0} opera.ion for a.grid-connected double-fed induction genera.or (DFIG) in a. oscilla.ing wa.er colum. power pla.t (OWCPP). This study presents a.novel optim.za.ion technique ca.led the circula.ory system.ba.ed optim.za.ion (CSBO) a.proa.h to develop six a.a.tive fuzzy logic controllers (a.LCs) with 30 pa.a.eters a.d com.a.e them.to cha.tic-billia.ds optim.za.ion (C-BO) a.d genetic a.gorithm.(Ga..
