  1. 1. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Rob M.P. Goverde; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver Advisory System; Catenary-free Operation; Electric Train; Electric Multiple Unit; Battery; Energy Efficiency; Energy Storage; Speed Profile Optimization; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. READ MORE

  2. 2. Integration of Battery and Hydrogen Storage with a Grid-Connected Photovoltaic System in Buildings

    Author : Yang Zhang; Jinyue Yan; Jianzhong Wu; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Photovoltaic; Grid; Building; Battery; Hydrogen Storage; Operation Strategy; Optimization; Energiteknik; Energy Technology;

    Abstract :     The integration of Photovoltaic (PV) with buildings changes the previous electricity consumers into prosumers. The reduced PV subsidies and the grid stable operation requirements are pushing prosumers from direct exportation to self-consumption of the produced electricity. READ MORE
