The method is based on the stability boundary locus. The stability region is displayed in controller parameter space and time-domain simulation studies are carried to verify the accuracy and effectiveness of the proposed method.eninfo:eu-repo/semantics/closedAccessLoad frequency controlproportional-integral (PI) controlstabilizationtime delaysArticle31182983010.1109/TPWRS.2015.24126782-s2.0-84925427652Q1WOS:000367298100085Q1
