One explanation is a mismatch between PV power and load demand, which occurs regularly in Japan around April and May. Voltage violations occur when voltage levels exceed the allowed limits. To prevent voltage violations, many methods have been proposed, including volt-VAR control on inverters. The effect of employing a dynamic volt-VAR control rather than a static volt-VAR control in a high-penetration photovoltaic (PV) system is compared to that of using a static VAR compensator (SVC) in this study. The reactive power involvement of the PV inverter can be adjusted using dynamic volt-VAR control, which takes into consideration the inverter's available reactive power capacity. The amount of available capacity will influence how forceful the control is, which will be reflected in the droop gain. The controls are tested on the transmission system for a year to assess the number of uncompensated voltage events. The number of violations that the control cannot compensate for affects how much reactive power the SVC must provide.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.144 No.2 （2024） 特集：令和5年電力・エネルギー部門大会本誌掲載ページ: 201-207 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/144/2/144_201/_article/-char/ja/ Show more
