  2. 11. 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 : 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

  4. 12. On the Efficiency and Accuracy of Simulation Methods for Optimal Power System Operation : Convex Optimization Models for Power System Analysis, Optimal Utilization of VSC-type DC Wind Farm Grids and FACTS Devices

    Author : Mohamadreza Baradar; Mohammad Reza Hesamzadeh; Damien Ernst; KTH; []
    Keywords : Electrical Engineering; Elektro- och systemteknik;

    Abstract : Recently, significant changes in electric power systems such as rapid developmentof smart grid and electricity market and integration of non-dispatchablesources have added more complexity to the Power Flow Scheduling (PFS) andPower Balancing (PB) models. For instance, non-dispatchable sources introducean increasing level of uncertainty in the electricity market and power system operation. READ MORE

  5. 13. Integration of Distributed Renewable Energy and Energy Storages in Buildings

    Author : Yang Zhang; Jinyue Yan; Pietro Elia Campana; Anders Lundblad; Zhe Chen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; PV; Energy Storage; Operation; Optimization; Flexibility;

    Abstract : Photovoltaic (PV) is a distributed renewable energy technology that is suitable for integration in buildings. PV reduces the electricity demands as well as the greenhouse gas emissions of buildings. READ MORE

  6. 14. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

    Author : Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Abstract : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. READ MORE

  7. 15. Optimal Engine Operation in a Multi-Mode CVT Wheel Loader

    Author : Tomas Nilsson; Jan Åslund; Lars Nielsen; Anders Fröberg; Lars Johanneson Mårdh; Linköpings universitet; []
    Keywords : ;

    Abstract : Throughout the vehicular industry there is a drive for increased fuel efficiency. This is the case also for heavy equipment like wheel loaders. The operation of such machines is characterized by its highly transient nature, the episodes of high tractive effort at low speed and that power is used by both the transmission and the working hydraulics.
