  1. 1. Steady state analysis of HVDC grid in the North Sea with offshore wind power plants

    Författare :Kalid Yunus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduled exchange power; NPV; transmission fee tariff; primary controller; ARIMA; external AC grid connection; secondary supervisory controller; meshed HVDC transmission grid; VSC HVDC; WPP;

    Sammanfattning : In this thesis, some of economical and technical aspects of expanding the HVDC (High Voltage Direct Current) transmission systems in the North Sea are studied at steady state. In the thesis, it is assumed that the expansion of the system is made by connecting WPPs (Wind Power Plants) to the system which is built for power exchange. LÄS MER

  4. 3. Optimal Energy and Flexibility Dispatch of Grid-Connected Microgrids

    Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; microgrids; Battery energy storage; optimization.; energy scheduling; energy management; distribution network;

    Sammanfattning : This thesis proposes an optimization model to efficiently schedule energy and flexibilities of a grid-connected microgrid (MG) with non-dispatchable renewable energy sources and battery energy storages (BESs). The model can also be used to coordinate the MG operation with the connected upstream distribution grid and to assess the MG flexibility considering economic viability, technical feasibility, and BES degradation.

  5. 4. Simulation of rail traffic : applications with timetable construction and delay modelling

    Författare :Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). LÄS MER
