The design strategy, which is based on a concept of adaptive controller, has fours step that are dominant mode identifying, controller output location, feedback signal weighting and parameter tuning. The proposed feedback signal weighting is to add weighting numbers to feedback signals using only one power system stabilizer. It is based on an optimal problem of maximizing the residue of the mode of concern for the feedback signal while minimizing those of other modes. Then the tuning process can focus on only the mode of concern. In this paper, the last two steps of feedback signal weighting and parameter tuning are performed using an iterative method. The proposed design framework has been tested on the IEEJ East 10-machine and West 10-machine systems. The result shows that the designed controller can improve the mode of concern significantly, while it can not affect much the others.. It is also seen that the design strategy is appropriate for a concept of an adaptive controller.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.136 No.2 （2016）本誌掲載ページ: 118-128 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/136/2/136_118/_article/-char/ja/ Show more
