However, the proliferation of renewable energy has resulted in several problems faced by the power systems such as surplus power and system frequency fluctuation. In this research, a battery in an electric vehicle is considered as a control device to suppress the system fluctuation and a new EV smart charging is proposed with four charging sequences. The total controllable capacity of the EVs is estimated based on the lumped EV model for frequency fluctuation problem. The results show the effectiveness of the proposed control by smart charging on EV which can suppress the frequency fluctuation. In addition, the customer's convenience is taken into consideration by using the satisfaction index defined as the ratio of charged energy to the required energy. Lastly, a sensitivity analysis has been performed to investigate the sensitivity of parameters of both the control system and customers' data.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.134 No.7 （2014）本誌掲載ページ: 579-585 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/134/7/134_579/_article/-char/ja/ Show more
