Modeling of Overvoltages in Gas Insulated Substations
Published by Tomasz KUCZEK, Marek FLORKOWSKI, ABB Corporate Research Center in Krakow, Poland Abstract. Gas Insulated Substations (GIS) are broadly used for transmission and distribution of electric power. Due to the interactions with a network and various environmental phenomena like lightning the GIS are subjected to the Very Fast Transients (VFT). Such VFT can beContinue reading “Modeling of Overvoltages in Gas Insulated Substations”

PV to PEV Power Transfer for Standalone Solar Power System
Published by Burak AKIN, Yıldız Technical University Abstract. In this paper, efficient PV to PEV’s li–ion battery power transfer is investigated. Dual-interleaved boost topology is applied to the PV to PEV direct power transfer system as DC-DC converter. Proposed dual interleaved boost topology is reached 97 % total efficiency with inversely coupled input boost inductances.Continue reading “PV to PEV Power Transfer for Standalone Solar Power System”
