Although the fault ride-through (FRT) capability was originally proposed for preventing a cascading frequency drop in the power system, the capability has the impact on other instability phenomena such as transient stability. In this study, we focus on the post-fault active power recovery of the PV systems. The impact of the recovery speed on the transient stability is investigated under different load conditions, static/dynamic load condition. Numerical examples are carried out for the one-machine one-load infinite-bus system, and the effects of the recovery speed are evaluated by equal area criterion and critical clearing time. As a result, we have found both desirable and undesirable effects on the transient stability depending on the load condition.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.136 No.3 （2016）本誌掲載ページ: 236-244 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/136/3/136_236/_article/-char/ja/
